Dolphins brain's are the smartest on the planet - A Dolphin, (do not take this literally and get triggered like the following people have 🤦♂️) It is tounge and cheek, the comment is pretending to be a dolphin commenting. I went on to play devil's advocate in the thread to explain that there is a lot if things we do not know as a race. So long and thanks for all the fish!
Maybe you'll still be alive when the technology to transfer your consciousness into digital format, and be stored, becomes available, at which time immortality will be rife 👍
Yes exactly! Humans have evolved on this planet with other micro-organisms like water bears, water bears have the ability to survive pretty much anything including the vacuum of space. Now think about it Earth quite possibly the safest planet in the milkyway maybe the whole universe yet the waterbears have evolved on this planet (evolved might be the wrong term) now imagine a planet like mars or even deadlier across the universe imagine the vast ability’s of them. The universe is so huge that I can put it into words. It would be stupid to assume that there isn’t life out there in this huge place. Maybe if your religious or believe we have a purpose then thats fine. Sorry this just keeps me up xd
@@joshirelax1071 yeah no I agree , like for example we can't breath under water therefore basically we can't live there , yet with technology we can explore there for some time , just like marine life can survive in water but not on land , what's to stop the same from happening with different planets you know
Right ! Some dude on the news was like no there’s no life on other planets shows how much lack of intelligence they really have when it took us billions of years just for a cell phone
There's a quite simple answet for that question. If you go to a super market you've never been to, looking for an apple. You could search in the toilette paper aile and the freezers. There is a possibility you might find an apple. But most likely you will find an apple with all the other fruits. We know for sure, that on a planet like ours life can evolve. So it makes sense to search for life on earthlike planets, rather then on any random possiblr planet out there. Hope thats helpfull. 🤙

I have always had a big problem with the concept of time travel. And it isn’t the traveling part that’s an issue. Let’s say it’s a given that we can now travel through time. The real problem isn’t WHEN we “land”, it’s WHERE we “land”. In movies, they always assume the point that you’re standing on the earth is the constant. But in order to successfully time travel, you need to calculate exactly what point in the UNIVERSE you will re-appear. Considering the earth is rotating at something like 1600 km/hour at the equator, and rotating around the sun at 107,000km/hour,and the solar system is moving about 700,000km/hour. Plus the galaxy is shooting through space. In order to do a simple time jump of, say, 10 minutes into the future, you’ll need to calculate the exact point in the universe where your feet will be 10 minutes from now. And it’s not a straight line, it’s a complex, spiraling, corkscrew path through space. And suppose your math is off by a few feet/a meter, you could arrive half buried in the ground, or floating in the air, or inside a tree, or any number of other gruesome possibilities. The calculations would be all but impossible. Unless you are time traveling by magic. Then I have no argument.
This is something I've had issue with since I watched the Time Tunnel in the 60's as a kid. The 2 travelers always fell right on the top deck of the Titanic (instead of say in the engine boiler or the middle of an ocean) or in the cow barn genesis of the Chicago fire, and they even did this separately finding themselves in the exact same place, all purely by coincidence. Too many artistic liberties, all for entertainment value of course, but it got me thinking about this topic.
I think it’s interesting that we always look at possible alien forms as “head, torso, 2 legs and 2 arms”. Nose, big eyes and mouth. If the universe is so big, the ways forms of life could present itself is also numerous. The chances of extraterrestrial life looking familiar is slim.
We based aliens on humanoid like figures cause that’s all we know, what if they evolved from different chemical compounds that aren’t carbon based, like how ufo sightings don’t have emission like how our jets use fire based engines, maybe they don’t need something like that due to how they’re tech is made.
Maybe we'll just never know because you cant travel back in time to whats already happened and just a copy of it or nothing changes physically because rewinding time might not undo the physical changes caused during that passing of time but just the time itself, just like telescopes view past events but in current time
@@mattball420 well technically everything happened in the past everything we hear is from the past because that sound takes time to travel to your ears.
It could be time travel exists or has existed and it's never affected us b.c our civilization doesn't reach that pinnacle.... or it's been achieved and some how our grandchildren perfected how we achieve immortality so the schematics were destroyed so we always come to an outcome of enlightenment
Or!!! Why can't everything we experience right now, in this moment, be the first time it's ever happened and there is no "future" to travel to because we are writing history for the 1st time ever?
I don't think 'traveling ' through time is possible. There are way too many variables involved. Every action a human or any animal makes effects his second to second existence . I did this (cause)& this was the result(affect) & there are 8 billion people on our planet making decisions & taking actions or making decisions & NOT taking actions all day, every day, nanosecond by nanosecond. This literally creates our reality unless, like some sci fi material such as Westworld has speculated, it doesn't. That free will is mostly an illusion & that humans are so predictable that if given the opportunity we would all make the same decisions, & make the same actions over & over & over again with the same predictable results or affects. That there are actually a few moments in each of our lives where we really do have free will & the ability to actually change the outcome of our futures but we mostly blow it because we either don't sense the moment or if do we simply make the wrong decisions. Michael Crichton wrote a book called Timelime a few years before he died that was very interesting. Yes , there was a movie adaptation . No, it's not good or really faithful to the book at all so don't judge this from that movie .Definitely would recommend you read the book though. This is actually possible(in theory) & though not technically time travel it may be the closest thing to it that humans might have a shot at achieving one day.
Time is merely an idea which happens to be very useful as a form of measurement and it’s not even consistent across the universe but it helps us keep track and organize so many things.
It's funny that you say time is an idea. If there is a single thing that it's clear that exists outside our brain that we are aware of, that is time. It's like "I think ergo I exist", but actually correct: that "I" is ambiguous because we don't fully know the nature of ourselves. But that doesn't happen with change. If we perceive that things change, something MUST be changing. Probably not what we perceive, probably not as we think it changes, but definitely something changes. Whether it's just "movement" or an alteration of a state. Because if there were no changes at all in the universe, the phenomenon of us perceiving anything would not be possible. The only thing that we can be sure of is that change exists. Time exists.
@JustDoIt12131 Would it then be right to say that time as we call it only exists because we observe change? Change is constant of course, but we have to label and characterize it somehow to place it in our reality. Isn't that where the idea of time itself originates?
Time to me, Is something us humans created to understand where we belong in"time" I believe the cosmos has no time. No beginning and no end. Meaning space has not a beginning and if it doesn't have a beginning it can't have an end. Literally "forever"!
@@Jeff-fd8sc No, time doesn't only exist because we observe change. It's the other way around: we observe it because it exists. Time and change is the same thing.
that's true but also we have hardly looked anywhere yet. If there is one civilization per galaxy (so we are the only one in ours) then there are 2 trillion galaxies which means 2 trillion civilizations. But since we can't even get outside out solar system, let alone our galaxy it's highly likely we haven't seen them
I am a physicist and I wish I hadn't found this video. This is the classic example of why physicists HATE media who is just bothered about making things sound fancy without even a shred of proper interpretation in them. Each and every one of the paradoxes mentioned here is so badly represented and I feel like killing the creator for murdering physics. Not to mention some of these are not even paradoxes, they're just laws which the person didn't bother to read.
Don’t even get me started mate. It is complete utter asinine and disrespectful to science to misrepresent this information. If anybody wants to be a science communicator, they should at least be able to explain theoretical or known phenomena like a scientist. This channel fails to do so.
I suggest you look at the channel “Cool Worlds”, your thirst for actual scientific knowledge will most likely be quenched if you do so! Stay curious my friend!
I'm 50 years old and remember being in school was told about the universe and the big bang and figured we as humans were approaching the end of the line in science and human technology. Little did I know we're not even scratching the surface of knowledge there is to know... now it turns out, the universe is accelerating its expansion, there's some dark matter and energy we can't measure or describe. The universe of the small seems to be getting smaller by the minute, and nanotechnology is not even completely understood, neither the true nature of our surroundings... We humans are stubbornly destined for nonstop surprises in our quest to find out what is this thing we call the universe
As we learn more and more about our universe and our place in it the more scarier and more thoughts we have to keep us up at night. People from 100 years ago had nowhere near the same thoughts that are on peoples minds today. In fact it’s entirely different because back then they didn’t think about Climate Change. Large Asteroids, gamma ray bursts, rogue/dormant black holes etc.. what will be some of the biggest fears 100 years from now? It’s a scary thought.
@@TnerB91 your being ridiculous if your sacred ... if all this is happening now what do u think has happened are entire existence... we have lived here for quite awhile if I say so myself and nonthing has happened
The scariest part is dolphins can wreak havoc day and night without sleeping. A recent study found that dolphins could stay awake for five days straight with no loss of mental acuity. The dolphins didn’t even need to make up sleep at the end of the study, though the scientists sure did.
I recall an old Star Trek episode that had a sentient creature called the Horta. It was a silicone based rock creature that did not show up on their scanners. Basically a living rock with intelligence, protecting her eggs. Made me think at the time of all the possibilities in the cosmos. Growing up in the 60's and 70's, this was mind blowing.
I remember that one. They blamed to killing a few crew while they killed a thousand of her eggs. Made me contemplate mans morale and how we presumed to have greater conscience than other simple species.
@@shyamganeshiar oh yeah I remember that as well. Ages ago I used to play a kind of popular computer game, starflight, it became sort of famous in gaming because it was like one of the first big open-ended things where you could choose your own path. The big ending to the game was a story of how the fuel that that particular part of the Galaxy uses was actually an ancient being that began causing suns to go into supernova because everyone was using it to power their ships lol. Pretty sure that's how it went
“The human brain is one of the smartest on the planet” Observe a four-way stop for about five minutes and you’ll immediately lose all hope in humanity.
We haven’t been contacted by aliens for one of several reasons. 1. Any civilization who is advanced enough for interstellar travel has also developed technology of mass destruction and destroyed itself (like we will) 2. Any civilization advanced enough for interstellar travel recognizes that humans lack the intelligence and foresight to be a multi planetary society. 3. They simply haven’t discovered we exist yet and will find us eventually 4. There are other civilizations but they are actually less evolved than ours and have yet to develop space travel 5. The most horrifying of the options. We actually are alone and intelligent life has yet to evolve elsewhere.
I assume you’re talking about the Fermi Paradox, though I haven’t gotten to that part of the video yet. The Fermi Paradox has so many assumptions that it’s laughable. Everything about it is explainable.
You're watching too many Holywood alien invasion movies assuming that an intelligent species would evolve in a manner that would seek to destroy each other (such as we do currently). These civilisations are here and are actually doing the opposite: Making sure we do not destroy ourselves - as they have advanced enough to realise their mistakes. Evolution doesn't always have to result in destruction of ourselves therefore there will always be so many possibilities of life out there that not everyone of them will destroy themselves.
For the longest time, I've had a problem with the Schrodingers cat experiment. It seems to me to just be a tautology -- you don't know something until you know it. Of course the cat is not both alive and dead just because you don't know which it is. I'm writing this either at my kitchen table or the desk in my office. Since you don't know which, does that mean I'm in both places?
The problem with that fancy new telescope too is that even if we can look at the surface of a planet on the other side of the milky way for example, that light or image we see is technically that planet in the past because it took so long for the light to reach us. Depending on how far away the planet is it could be 100s of thousands of years in the past and maybe life is blooming on that planet, we just can't see it yet.
and the aliens might have the exact same problem, they se earth but it looks like it did before the dinosaurs, just a vulcanic planet whit no possibilty to sustain life. so for us to find a planet that actualy have life on it, we need to be able to find a planet that is 100 times older than earth that has had life on it for biljons of years or so.
We might detect life and somehow develop a method of travel to go places nearly instantaneously and when we get there they'll already be extinct. We'll find some preserved records of them looking at earth before life arose and deciding to just not go there.
Most of the times when we talk about extraterrestrial life we tend to focus on planets which have similar living conditions as that of earth but that will only stand when we are looking for extraterrestrial life that is similar to ours. There could be other life forms which could function normally in a sulphur rich atmosphere or with winds at 5.4k mph and in that case even bacteria found in another planet are actually aliens.
bacteria from another planet could also wipe us out easily as we'd have no built-up immunity to it. This is the same in reverse i.e. us bringing extinction-level diseases to other planets that to us wouldn't even cause a cold, which is an actual concern of NASA's
That in and of itself could be a paradox. Our instincts and experiences as a species is limited to only earth. It's like what they say about people you see in dreams. You are unable to make up a face, any faces that you dream of will be someone you've seen even in passing. Same idea can be applied here, we are unable to think of another form of life that doesn't share our similarities and environments. Everything we think up of will have a resemblance of either a human, an animal, an insect, bacteria etc, even if you think of a floating white orb, that's how most civilizations perceive souls. So it really can't be answered until we meet something like that. One thing we can maybe say is that advanced civilizations could transcend into a mechanically immortal life, existing as a program or some sort of technology. Even that is ideas from our own species, we are not capable of thinking outside the solar system sort to speak lol.
@@Anten-Isy I get what you mean, but we know for a fact that the universe consists of a finite set of elements that we understand the properties of quite well. If you assume life to be reasonably complex, you need a building block (life as we know it is carbon based for example) from which it is based. Only so many elements / molecules provide the characteristic to be a building block (carbon is tetravalent which means it can bond to 4 atoms at once). Energy needs to be absorbed and emitted in certain ways as well, so I'm sure scientists are looking from a more general perspective such as "what is producing these odd energy patterns, it could be life", rather than looking for a planet that specifically looks like Earth. Carbon and silicon can form solid structures within a certain temperature range for example, so they probably look out for factors such as that. I still agree with the fact we have no idea what alien life might look like, but at the end of the day it is still bound by the same chemical and physical laws of the universe that we are.
As a theist, I consider the creator and the creatures described as angels as extraterrestrials and don't have that feeling that we might be alone. But I certainly can understand how one might feel if the existence of aliens depended on abiogenesis followed by evolution.
The fact that we’re only basing potential life off of planets with conditions like ours. Who’s to say all other life forms IN THE ENGIRE UNIVERSE need oxygen and water?
@z3bladeworksoutdoors227 Everything on this earth involves absolutes, even the laws of physics's which are laws of nature are absolutes! Even in our time domain in this reality is completely the laws of absolutes! Now if you take the time to read not only in the bible, but even actual events, once again absolutes , now research creation science once again absolutes prevail! Now go into studying a single cell in the genome of the human body , and any other mammal. Once again the laws of absolutes! Lastly become an astronomer and study planetary bodies in space, guess what , the laws of absolutes! God is showing us all his creation in just six days, absolutes! So I tell people just like yourself, believe what ever you choose to! But I will base my understanding on God's creation, and the laws of physics he created for us to study, learn, and appreciate. Jesus makes a very interesting comment. My people perish for a lack of knowledge!
The problem with time travel is that you have to go back to the exact location of earth in space at the date and time you wish to travel to. Seeing how the gallery is moving and your solar system is moving with in that and the earth with in that. Pin pointing the exact location and getting to the location in space is just a challenging as figuring out how to go back in time once you get there.
Lets suppose a civilization is advanced enough to figure out how to travel in time. I think it would be advanced enough to solve that problem as well. I dont even think it would be that hard (in relation to traveling through time in the first place anyway) as all it requires is enough computing power to calculate all that.
i believe time travel to the future is able to be done only if going the speed of light, but there’s honestly no way to go back to the past to change what happened
The fermi paradox is based on the assumption that other "advanced civilizations" would also be willing to expolit and destroy thier planets to build the technology we are looking for to prove thier existence. There is absolutely no logical reason for this assumption. Not every creature is as short sighted as the human species.
Not to mention that even if there were other civilizations similar to us, looking for life and possibly having the technology, they could have died out million of years ago. They could be so far away, even within our galaxy, that traveling here would be impractical. Like us wanting to send a mission to Alpha Centauri. It's only 4.4 light years away, but it would still take us 6,633 years to get there at our current fastest speed of 450,000 MPH. And even if they knew we were here and just wanted to send us a message, depending on where they are in the galaxy, even that could take thousands of years to get here. It's a false paradox imo. It's the equivalency of some remote tribe 10,000 years ago thinking "We must be alone on this planet, other wise, where are the people??"
Unless it is you who are short sighted and other civilizations don't see it as "exploit and destroy" rather doing what is necessary to gather the resources for expansion.
well humans are nuking the only air water fertile land they have, i wouldnt be surprised! exploiting every sentient being for flesh bone skin reproductive system.. i wouldnt be surprised at all
I love to see the story of Dr. Wudi. He observed timelapse of all Universes. He holds a very different view. He has an unusual Theory of Everything. He has been observing in silence since 2017. If you make a video about him, I think it would be a truly fascinating story.
I lived in a rural neighborhood in the forest in northern AZ as a teen and went on many hikes in the forest. To find artifacts left over from the native or wild west cowboy camps I would have to dig down to find them because they were buried from time passing. Trees dropping pine needles, wind blowing dirt, rain burying things in mud, etc.. I would clear rocks off the area before digging down to find the artifacts. If the artifacts are from the past 150 years or so, why are rocks that are millions of years old sitting on top of the ground above them? Many too big to have been blown there by the wind. Shouldn't the rocks have long been buried in time? I would find large and small chunks of petrified wood sitting openly on the forest floor, even though it's surrounded by pine trees. Shouldn't it have been buried under pine needles and everything, given how old it is? Some you would think someone just put there a week ago. How are so many rocks that are millions of years old sitting openly on the top of the ground, above things that nature buried in the past 100 or so years? Not really a paradox but something I used to wonder as a teenager.
It is possible that the Younger Dryas impact event very suddenly melted half of the world's glaciers very abruptly. The ensuing flood in your area was a literal ocean of water pouring down southward, tearing up the entire landscape, washing away entire geological strata, exposing very old features.
I'm higher secondary student and studied about light and it connects to schordingers theory . Light can be Ray , Wave or partical as you observe it . Normally light appear as a ray like it reflect and refract . In YDSE ( Young's double slit Experiment ) it behave like wave , show interference by fringes . And in Photoelectric effect the classical wave theory fails and give rise to it's partical nature and also give idea to dual nature of matter
I think when it comes to intelligent life in the Galaxy it's more about when instead of where. I have a feeling that advanced civilizations flicker in and out of existence...
UA-cam has a video that highlights the robustness of life in the universe as only a very small part of its overall time line. Like akin to only a few seconds in the life of a human.
Could be. The numbers are so vast though - so inconceivably vast that the sheer statistical odds is that many thousands of civilizations have continued - maybe in ways hard to imagine. Perhaps they disappear into their machines - occupying virtual spaces instead of actual ones. Maybe physical biology is just a baby step of the evolution of intelligence. There is so much we don’t know it’s difficult to even frame the questions. It truly is mind boggling.
Kevin Brooks that's interesting . Once you wrap your brain around the incomprehensible size of the known universe & the time frames involved its an idea that's started to gain some traction in recent years. You know there's really only a couple of movies that takes this concept & runs with it & that's Forbidden Planet & the original Alien especially but just as a standalone film without considering the prequels at all. What essentially happened is that ship really just stumbles into a scene from some kind of cosmic nightmare that is supposed to have played itself out a long, long time ago. Unfortunately for the crew of that ship one small piece of that nightmare is still alive. Finding the remnant of some long dead civilization is, in many ways, more realistic than straight contact and Alien really capitalizes on that fear of the unknown factor better than anything still out there
The other thing is we search for signs of our life and technology. An advanced civilization could use a totally different system we don't have the technology to detect. Not to mention when it comes to the universe distance is the biggest problem. Who knows 200 years ago maybe we were getting signals from a civilization that took millions of years to reach but the planet is long dead.
as it says if one can time travel then it should be able to come back so that is not the point here, point is , is that a new reality on a new time line to which then he said that some physicsts have come with solution to send trajectry from future so that this travel in past and back to present can be done via the same wire(timeline) hence remaining in the same timeline.
Countering the Fermi paradox, if you look at the time line of the earth's existence and specificaly the total period of time that human life has existed on earth, it is a tiny blip in time over the time line of the existence of our universe. So potentially we may have came to existence after other intelligent life ceased to ocupy our local area of the universe, or other intelligent life may not be evolved yet locally to us, given how big the period of time the universe has existed so far and likely to continue.
The Fermi paradox is like the Drake equation. Since there is only a single planet we know of with life on it, any other numbers we use in our formulas become an example of GIGO
Many of these are the exact same paradox expressed with different stories/scenarios to explain the elements. The root of the paradox is "just how does time work" to which much of science is preoccupied with figuring out, breeding hundreds of thousands of interesting questions.
Time is just another physical spacial dimension. It is pretty simple to understand. I can say scientists already know this, for a good while now. It is just regular society who still is uneducated about it.
@@fernandomartinez4486 sadly this is objectively untrue. At any point in history scientists largely believed they understood time so the changing information proves they did not. When mankind genuinely has a solid understanding of new knowledge, it empowers man to do things they couldn't do before. The existence of these paradoxical questions and man's lack of empowerment to do anything new with time, demonstrates that scientists do not yet have a good understanding of how time works.
One problem with communication over interstellar distances is just that. The time it takes for radio signals to travel from one star to even the nearest makes it very impractical. Also, the ability to detect signals that have dispersed through space and over the inference in space makes it exceptionally difficult. Look at the Viking probes. If we didn't know they were there and exactly where to point our radio dishes it would be virtually impossible to detect their weak signals. Most civilizations out there probably use some focused beam tech to communicate which would make it almost impossible to intercept unless you happen to pass through the beam. So unless they come to our planet, it's unlikely we could ever find them by looking for random radio signals.
This is a problem for us and our tools... what if some aliens have a completely new way of comminucation, a 3 thing. That we can't wrap our minds around
@@dd-fz3ku true. Communication through comprehensive ideologies allows for "intelligent talk/language" ... So all the ants and bugs talking to each other and constructing geometric masterpieces is nonetheless applied comprehension, whether it is instinct or learned. Anybody speak ant?
A sad example of this is there was a signal received that translated to a distress call for help from a very distant star that went supernova. However, it was already too late by the time it was received and there was nothing we could have done as this star was millions of lightyears away and although the supernova was viewable from Earth, it took just as long for the light from the supernova to travel for it to be seen from Earth. The distress call did come first before the supernova was observed happening but, even if we wanted to help, it was already too late because of the distance.
@@stevenslouber4947 yeah that's a cool story and equally untrue. If we'd received a signal from ANYWHERE it'd be worldwide news. How come I'm only now reading about this alleged "distress signal from a star"? I think you're taking us for a ride here, Stevie
@@jontraz5993 He said an "Example", not an actual occurrence, and what makes you think it would be worldwide news? They only tell us what they want us to know!
This by far has been one of the better videos made. I hope eventually some one makes a video explaining each one of these to a t so that people that haven't researched these can understand what this person is talking about in each paradox situation
I'm sure there are probably dozens of videos explaining in detail every one of the topics covered in this video, one just has to be interested enough to look for them.
There really is no such thing as a Paradox, the universe is logically consistent and anything else is either a fabricated "what if scenario" or lack of clarity.
Perhaps we are living in a simulation. This would explain why there would only be one inhabited planet in our universe despite the astronomical odds against that possibility. It would also explain why light behaves like a wave when nobody is watching and like a particle when someone is. It would also explain why quantum physics are so strange and different than normal physics - because the beings running the simulation have to impose limits to prevent us from being able to determine that we are indeed in a simulation. (Limits like the our fragile planet with limited resources, our delicate bodies, the hostile environment and vastness of space, the one-way linear flow of time, the speed of light, not being able to find any black matter despite it making up most of the universe, never being able to reach or see anything beyond 46.5 billion light years from Earth or beyond the event horizon of a black hole, or anything smaller than an atom, only being able to experience three dimensions, only a rudimentary understanding of how quantum objects exist in multiple states, quantum entanglement, etc., etc.)
True, the one we seek, is the one who sees, who is the creator of the simulation? Perhaps our spirit creates the simulation for are selves to learn spiritual evolution (love) at a faster rate, or perhaps the simulation is just a game for us (entertainment)
Here's something that seems like a paradox to me, but could probably be explained by a physicist: Imagine a totally dark room with a lamp. You switch on the lamp and now you can see all the room. You can see because the photons bounce off (reflect) all the surfaces in the room. Now turn off the lamp and it instantly gets dark. What happens to all those photons bouncing around in there? Why do they just instantly disappear? Probably a stupid question, but it bugs me.
They get absorbed by the walls, when a beam of light comes in contact with an object some photons get reflected and some get absorbed, but if your room was somehow made of a completely reflective material and you were wearing that same material then the room would stay lit. But we dont know of any such material yet
So if the walls of the room are mirrors then the light would bounce around longer then in a room with black walls, but we are talking about insanely short amounts of time here because light is so fast and youd never be able too actually see the difference
They don’t disappear. The speed of light is just so fast that it appears instant. Even if you were 1 km away from the light source. That will be 1/300 000 of a second.
Its matter. First you must ask yourself where are all the photons coming from? From the light source they are blinking into existence. So if photons can appear into existence they have the ability to disappear just like they appeared in the first place. In a 4d universe, objects will appear and disappear to our eyes because our brains cant process what a 4d object looks like. So maybe theres a bigger picture to what light/photons actually are. We wont see until we reach the speed of light.
There may be a flaw with schrodinger's cat paradox. The scientists are assuming that the cat won't interfere with anything inside the box. The cat is unpredictable.
I also think scientists are assuming that the cat won’t interfere with anything inside the box. The cat is unpredictable and may try to escape, scratch the box, or tamper with the apparatus. This may affect the outcome of the experiment and invalidate the premise of the paradox. In fact, some interpretations of quantum mechanics suggest that any interaction or observation, even by the cat itself, could collapse the superposition and determine the fate of the cat. The Von Neumann-Wigner interpretation does talk about this. The cat's state was already determined before the observation; it's just that we didn't know until we looked. I could be wrong though
@@Molden-Mat duuuuude its not about quantum mechanics or experiments, its a paradox. its something you realize, not a question you answer. there isnt an answer. look at the munchausen trilemma
When it comes to paradoxes in time, i have seen it done beautifully in one series so far "Steinsgate" How to save someone life without creating a paradox in time? Lets assume that we travel into the past (lets say 5 years) so save someones life that died 5 years ago. How can you save that persons life without creating a paradox in time? Stupid as it may sound, its very simple: Save that persons life, without letting anyone know that they didnt die. The events traveling their death have to transpire the same way, and the person has to remain "dead" until you reach the point in time you travelled back from. After that the person can reveal themselves as everything hence forth wouldn't create a paradox anymore, because you never reached that point in time before travelling back in time and up until then, everything had remained the same as you have known. you could either simply bring the person "back to the future" which would be the most failsafe way of doing things without creating a paradox, or make sure they dont effect the timeline in any way during the time of their supposed death. As long as the records stay the same up until the moment of time traveled back from, nothing changes. this sounds logical to me anyway. However, there is one good counter argument though: Time is not owned by humans, meaning, just because we dont know about something happening or not, doesn't mean the universe isn't aware (as stupid as it may sound) The person that died in the original timeline did not disappear from the universe. the particles the person was made of still remain in the original timeline and in one way or another effect the original timeline, as minuscule as it may be. and the absence of that effect of the timeline may cause a paradox in itself. ... or not, who knows. this shit is so complicated, ill go watch some mark wahlberg movie
It’s valid …Only if the person was dead somewhere where you was never find. Like that when you save the dead person the things will happen as it has always happened.
Was wondering if anyone else caught the incorrect years on the WWII bit lol I was like...is this an alternate timeline where it lasted 40 extra years? 🤔
You know it's weird to me that people are so willing to examine the Fermi paradox before we even have a full replicable understanding of how cellular life forms from basic elements. Resolving the latter confusion is irrevocably essential to resolving the former confusion.
Well I don't really think so. It's like psychology and let's say geology. Together they all make humanity but they are both fields of study that have nothing to do with eachother. We were able to build a floating laboratory/city in space before we explored 20% of our own ocean. We put men on the moon before we realized that smoking kills people. Alien life more likely than not will share nothing of our own physiology, so technically we could advance on the second confusion without touching the first one. If you want to look at everything in the lense of biology then yea technically we need to figure out how cellular life forms so we can expand our knowledge about what the possibilities of life forms are, but without first meeting something from out there we would have nothing to work on, only theories which without evidence wouldn't stand. There is a moral question in your example however, should resources be allocated to studies which don't really give any real benefit when we could allocate it to research and development of technology or medicine that is useful for the betterment of society. Isn't it a little cocky that we dip our feet in space before we get our life expectancy to atleast an 80 everywhere ? So your point stands in a moral/ethical light but scientifically it shouldn't interfere one and other.
You also have to consider that reversing in time is impossible as a solution, and the only way around it is to enter a near perfect copy of your universe before times progresses to the point you want to enter. It is far more logical to assume the system we exist in lacks the ability to properly rewind, going forward has already been proven to exist but not backwards. Also this idea is supported by thermodynamics, the reversal of the system would violate the common laws we know to exist.
The only feasible way to time travel into the future is to wait it out ... in a conscious or unconscious state ... in reality that's not time traveling ... let's see this proof
I think we just can’t travel backwards fast enough. Like trying to go down an up escalator or up a down escalator, we can sometimes go faster than the escalator and make it off going the opposite way but time moves forward too fast for us to move backwards
thermodynamics only exists under our presuppositions of time. if time were a plane instead of a line, then thermodynamic systems would be only the areas of that plane that flowed in a straight line. although it would only violate the second law
The double slit experiment has some misconceptions. This used to fascinate me before I learned the true nature of the experiment. When they say “observing” changes the result, they really mean when the particle is being sensed by our equipment. They fail to clarify that the equipment used to “observe” actually has some Interference with the experiment.
Today I learned about the Astley paradox! If you ask Rick Astley for his copy of the movie UP, he cannot give it to you as he will never give you up. However, in doing so, he lets you down. Thus creating the Astley Paradox.
There is a time travel paradox that it seems no one ever covers. It begs the question ... Can you travel into the future and meet your older self? You know that unless you die, you will become older at some future date, and if time travel should be possible it seems to be a reasonable thing to do. But what if you decide to never return to your initial time of travel? How can you ever become the age you expect to meet at that future time? Yes, you can go back (if this sort of travel ever exists) but you don't have to.
I wish my younger self could visit me now (age 78). I could warn my younger self of all the stupid things I did and try to convince younger me to be smarter. Would I then wake up in a different situation - because of the better decisions my younger self made - because of the warnings? I wish.
the video is basically saying if you’re blind, nothing exists. If I take my glasses off and can’t read a stop sign I guess that means it doesn’t exist!
I think the problem with the double slit experiment is not the photon. It doesn't care if it's being observed. The problem is the observer. We are not capable of observing paradoxes. So when we make a deterministic observation of that this photon is up to, from the observer's POV the wave collapses. In according with the theory of parallel universes, the interference pattern is still there, we just don't see it because making that observation, coupled with our inability to observe paradoxes, only allows us to see one outcome.
I agree with you, only change I would make is that I personally don't believe there is a paradox. We only see a single outcome because we are apart of this universe. I think its probably much more simple than we are making it out to be. I think that anything that can happen does happen in another reality and when we observe the photon we are interacting with the photon causing it to show the outcome that was always going to happen in the reality of the observer. In fact the experiment may prove the exsistance of fate.
But what is the mechanism that causes the wave function collapse? A “deterministic observation” in the context of the double slit experiment should have no effect on the photon. In fact you can leave the measuring apparatus in place and just scramble the results with a computer preventing which way knowledge and the wave function is reestablished. I think the key here is when you say “from the observer’s POV”. Reality itself, as in a space/time matrix with locality (objects with actual location relative to the observer that are collapsed out of just potential ) maybe manifested by a sublime interaction with a form of consciousness more fundamental than space/time.
@@LiteShaper1 Its the interaction of the detector that causes the waveform collapse. Well you can believe what you want but I don't personally believe a consciousness is required. Science had to at least consider the possibility a hundred years ago when quantum mechanics and the double slit experiment were still young but the vast majority of scientists have long since moved on.
I’ve heard it said that time doesn’t really exist, it’s something we invented to give us familiar reference points. But then how do you explain aging? Everything gets older. So time must then exist? But what time is it in the void of space? So time only exists on planets, and only on planets with intelligent life? But that supports the idea that time is only an arbitrary reference point that doesn’t really exist. And how would this affect “time travel?” How could we “go back in time” if it doesn’t really exist? And where is/was the starting point of time? If there’s no universally agreed upon starting point, how do we calibrate it for time travel? And whose clock do we use and how/when was it calibrated and is it completely accurate over multiple millennia? And what about “leap year,” times zones and daylight savings time? I need these answers by tomorrow.
Robert A. Heinlein wrote two of the best time-travel stories - "-All You Zombies-" and "The Door Into Summer". Carl Sagan listed "-All You Zombies-" as an example of how science fiction "can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader".
On the Fermi paradox, is there anyone who may have suggested the possibility that an alien race could have advanced beyond the point of individual existence and has become a type of collective which exists beyond a physical body. A sentient energy so to speak.
@@omidfarhadian2560 thanks, you really hit the nail on the head there. That’s exactly what I was asking. Edit: emoji and all, u just really wrapped it all up nice. Great job.
The solution the observer paradox is that when observed photon interacts with the photon received by our eyes changing its behaviour , this is also the reason for the wave function collapse and heisenberg,s uncertainity principle .. Now , where's my noble prize ?
So my theory on the bootstrap paradox is that when you go back in time, you're creating a loop and time is no longer linear and a loop has no beginning nor end.
have u ever played ocarina of time, it has a very famous song in it that was played to u by and old man who said a kid played it for him and its stuck in his head and will never get it out, and when you go back in time and play it for him and he loves it and says he will play it forever, who taught who the song?
The universe has the built in property in the present such that time travel cannot change those events. You create a time loop. It will always be just out of reach and you have to make the same decision. Also, in a time loop if something has happened in the past, it has always happened (e.g. you did not change it). But, the universe's built in limitation does not take away from free will. Conduct your life to allow for possibilities if you ever suspect you might be in a time loop. The movie "Triangle" does the time loop well. Although in that movie, there is another copy of "you", present "you" cannot interact with past "you" in any way that will change the future. I believe time loops are finite and they are usually short time periods. You probably won't realize if you are in a time loop.
Well with the Hamlet paradox and time travel in general, when you go back in time and change something, that creates almost a branch in another direction, it creates a different timeline.
The observer's paradox has completed f*cked my life up. So many different sets of eyes are basically ripping my reality apart. There's so many alternate versions of my life. I wish people could understand how NOT normal it is just sitting around watching any given individual.
The Observers Paradox (Shrodinger): Does anybody ever say what happens to the observer when, on opening the box, they find a very angry, very much alive, maddened ball of spitting, sharp-clawed fury?
No matter how much we try to change our own life paradox’s, there is more we can think of or just may not be able to think of immediately Our actions have positive or negative consequences that affect outcomes: how we treat others, how others treat us, how we affect each other, the unknown affects we have on others without even realizing it, ect.
@Repent to Jesus Christ! I have repented many times, I have kept an open mind, read verses from the Bible from time to time l, there are many things in the Bible that have many meanings I am quite sure. In the days of the Bible philosophers would often mistake stars for god or god’s, but that is a mistake because the Bible says you should not have any God or Gods’ before God - I forget which verse says that, but you can look it up.
@Repent to Jesus Christ! Thanks for sharing the knowledge, Remember that the Bible tells us to have no judgement or resentment onto other people or ourselves and keep spreading the knowledge.
I heard a quote once, something along the lines of ‘we are either alone in the universe, or we’re not, and both are terrifying’. If we destroy this planet through nuclear war or mass extinction. We could potentially be wiping out all consciousness in the universe. The universe will no longer be experienced, the universe will be silent again. A spectacle of a show to an empty theatre.
Well, I think that we are not the only living species in this massive and immeasurable space, and here's why. It is estimated that there are more than *100 billion planets* in our Milky Way galaxy alone. It is also estimated that there are more than *200 billion galaxies* in the *"observable"* universe. So if there are 100+ billion planets in one galaxy, how many planets do you think are there in 200+ billion galaxies? Now, we never sent probes to gather data on all those planets, so why would we assume that we are alone in the first place? That being said, I think there is a very high chance that there are lots of civilizations out there, but we are just too far apart to even make contact. And if these civilizations are too advanced, why would they seek us out? We are currently a type 0 civilization. Any civilization above type 1 would never care to contact us because we are inferior to them. At the end of the day, we really have no idea how immense the universe really is. There is a huge probability that there is an infinite number of galaxies, since it is said that the universe keeps on expanding. So, can we really say that we are the only living beings in this vast and unexplored unknown that is the universe? Are we really that special? Don't forget, we are only talking about the observable. We still don't know what lies beyond the observable.
@@prod.heysus2838 There are endless planets just like ours and even better ones, and yes, we can't reach them because they are light years away. The problem with NASA is that they keep on looking for extraterrestrial life on Earth-like planets only. They keep on assuming that if life exists out there, it has to be on a planet that has the same conditions as ours, which is very wrong. We never know if extraterrestrials might be able to adapt to harsh environments that us humans can't. Maybe ETs don't need sunlight, oxygen, and water in order to survive. See, scientists always seem to hold ETs to human standards, which is a big misconception. Always think outside the box regarding interstellar space, because the reality inside our solar system is so much different from the outside. That's why science is always evolving.
The quote is from the author Arthur C. Clarke. “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
The Observer's Paradox / Schrodinger's Cat Box always struck me as less an exploration of quantum states and more an exploration of the learning limitations of our observation-based method of scientific inquiry. Those who take the paradox literally are suggesting that reality doesn't coalesce into certainty unless it is observed, but doesn't this suggest some sort of nigh-magical power on The Observer while simultaneously undercutting the idea that the universe operates based on consistent, demonstrable principles? After all, if we believe that reality only becomes fixed when it is observed we imply that all unobserved locations and materials are inherently unpredictable and could do or be anything until an observer comes into play -- the irony being that, if the unobserved universe were truly so fickle, we'd have abundant second-hand evidence of the chaos it would unleash, which we don't. This kind of thinking, it reeks of the kind of limited humanity-centric medieval mindset that gave rise to ideas like Spontaneous Generation, Humors, and Miasma. The idea that the cat exists in both states at the same time is ludicrous, and I strongly suspect that all the "serious" scientific theories that stemmed from it will ultimately be set aside as our observations and predictive modelling improves. The Observer Paradox, as far as I can tell, is just an outlet for people who never fully wrapped their heads around the early childhood concept of object permanence. Prove me wrong.
You just got my like and subscribed and you didn't even had to mention this to me. Just science and stick on the subject. Well done Sir, I am your newest fan!
I'm sure I just don't understand it, but I dont see how not knowing if a cat is alive or dead affects the state of the cat. If I flip a coin and the coin lands on the counter and I cover it with an opaque material without looking at it, the coin is still either on heads OR tails, irrespective of its statistical probability before the coin was tossed, or my knowledge of the result.
It doesn't affect it and can't. The so called paradox is childish. Just because we don't know, it doesn't make it a paradox. If my friend lives half way round the world, I have no contact with them for a year so don't know if he/she is dead or alive, it's not a paradox, I just don't know! All paradox are are simply our inability to comprehend, failures in our understanding. Fact would not include any paradox. We invent paradoxes! Is time travel even real? Yet we invent a paradox on something not based in fact but mathematical equations, human constructions! The only valid paradox here is the double slit and like the others I think it's due to our limited/false understanding.
The paradox is very poorly explained. The gist is that what you describe for the coin doesn't apply to a particle decaying. Its state is undetermined until it's observed. Not undetermined in the sense that we don't know, like for the coin, but actually undetermined, like a coin that would stay in the air and never land until you'd look at it. Or rather that would land on both sides at the same time and only "pick" one when you look. That is established at the particle level, but the paradox is : what if the state of the particle had consequences at a macro level, like for instance a cat dying or not depending on whether the particle has decayed or not. We know that the particule is in an undetermined state having both decayed and not decayed, until we check. So, is the cat as well in an undetermined state, both alive and dead until we open the box?
I imagine that if there are other civilizations out there they might be far beyond what we have contemplated. They might view our civilization as simply way to primitive to allow us to know they exist. I view one of the problems with humans is our ego.
It's alot more likely there mostly just very primitive and stupid were the only truly intelligent life form on this planet how many other life forms are there .. i would assume most aliens would be primitive based off thst .. your opinion seems to be biased and based off what u want ... because of movies and stories ... and not a actual evaluation of the odds ... the only thing we got to base other lifeforms off of is what we got on this planet ... and everything here Is stupid other then use ... there probably is more advanced species .. but it's high unlikely that there is many species 1000s of years ahead of us ... intelligent life as we know it took billions of years to happen ... the universe is very old but it takes a very long time to develop life and planets ... the majority of life out there is realistically just bacteria
If information cannot be destroyed, does this mean every thought a being in the universe ever had still exists in the universe? And if you think about something that physics don’t allow, does it exist because someone thought about it?
The only answer to the bootstrap paradox that seems to make sense would be that if you went back in time with that copy of Hamlet, the instant you got there would start a new time line branching off the timeline you started on. Both branches would still exist but your conscious mind would be in the new branch. In that case, Shakespeare wrote Hamlet, just not on the branched timeline you created when you went back.
Hold on, question about the observers paradox So the whole cat experiment went through and you didn’t know the cat had died unless you look in the box. How does the change the fact the cat died? Things constantly happen without us knowing, how does us not seeing something or not knowing something make that thing not happen?
Yes and if you also consider probability’s of this happening are extremely high you can take a very educated the guess and basically know for sure this cat is dead therefore you know the answer before you can confirm
Exactly. Like when neptune was discovered by using mathematics. Astronomers knew that there was another planet affecting the orbits of some of the planets. They did the calculations and pointed their telescopes where the math said it would be and there it was. Neptune. So by the logic of the observers paradox Neptune did and didn't exist until it was observed... but yet it was surely affecting other planets... just doesn't make sense.
In this video, the paradoxes are versions for simple-minded people just for some WoW reactions. But if you watch the physicists version of these paradoxes, they'll get into much detail and keep you away from the popular misunderstandings.
Wait for twenty years. By that time the cat will have died of old age if it hasn't already starved to death. Or just take a whiff around the area of the box. If the cat is dead, you'll know.
Given that we still have basically no idea whatsoever how we jumped from lifeless molecules to living cells, you can't really put any stock in estimated probability of other life. It's literally the most important part of the equation. Doesn't matter how many planets could theoretically support life if it's never created in the first place (not to mention the millions of things that have to line up just perfectly for it to evolve into anything sentient, then to something as advanced as we are). It's not even a tiny bit surprising that we haven't found other life. There may not be any. Fermi isn't a paradox at all.
I wonder, with time measurements being so astronomically tiny, I wonder if you end up traveling back in time, and accidentally changed something, with all the timelines that would likely branch from that alone…. How would you honestly reach the exact same timeline you were on before? It would nearly and seemingly be impossible, right? Which would assume the point that anyone who tries to go back into your own timeline are likely to travel into an alternate timeline that you think is yours… and probably just isn’t… or can someone explain to me why this wouldn’t be the most likely scenario?
Take this with a pinch of salt, as it's heavily my own interpretation from a massive amount of sci-fi and physics consumption and a nice dose of nihilsm, but here goes: The issue here is making it human-centric, as we humans are so prone to do. A better interpretation is not that you are "creating" a timeline, but simply fulfilling the conditions of a timeline that already existed. A parallel universe isn't necessarily running in sync with ours on an equivalent timeline, they already have their own timeline with preset events, just like ours. Due to the infinite interpretation of Multiple Worlds, it's inevitable that there will be a universe that's so alike to ours but behind in appearance, that you, as a human who has to interpret things in relation to themselves, would assume that it's your own past. But it's not. you haven't even time-traveled at all, just been moved to a different location in a different universe. You aren't changing anything, because it was already going to happen anyway. You're not on your "own" timeline, you're in a parallel universe that you were always going to reach. "You" don't have anything to do with it, it was always there, you were always going to go there, and do whatever it is that you do there. Seems like you were already there with the part about "think is yours and probably just isn't", so kudos, you're on the right track, but you need to apply it to the entire scenario in a less personal interpretation. As for returning, if you have the sensational technology that allows you to dimension hop in the first place, you'd hopefully be able to use it to hop right back. As you rightly surmised, it was never "your timeline", just *a* universe - a location that still exists, and would continue to exist, for you to return to. In fact, you already did or didn't return, and nothing will change that because your original universe already has a set timeline, too. You might even hop back in on a different point in time, but that already happened if so, and we've just never gotten word of it. Think Star Trek Prime Directive, but for time travel (which is also a thing they have). A sort of half-way thought to use is that a timeline is only relative to you, and what you experience. YOUR past is a fixed experience, but so is your present and your future. Everyone else is experiencing the exact same phenomenon. For you though, the future doesn't exist yet because you haven't experienced it. Same for them: if you tell someone that you have come from "the future", you haven't, because that future does not exist for them, what you have come from is YOUR past. Is this more confusing? Maybe, but it's the best way I can rationalize it to work with our self-oriented POV. Naturally, we can't work out all these things beyond theoretical speculation anyway, because our 3D human brains can't interpret time as an axis. TLDR: Maybe you could go into "the past", but if so, you've already done that, it wouldn't be *the* past, and nothing would change. Thanks for attending my TED talk.
@@mudokon1004 yeah really. the concept of causality violation is.. unknown... and thus the entire dialogue is moot as it's speculating on physical laws that.... are impossible to experiment with. Thus the entire concept of time travel paradoxes is little more than fantasy.
I think it’s as hard for any as it is for humans to get to and travel space. We’re also animals.. and this type/scale of thinking is only unique to human beings..sure there is other animals on other planets but self aware animals like us gets less and less likely, imo
The cat paradox always makes me laugh. No, the cat isn't dead and alive at the same time. Just because you can't see it it doesn't mean it's in both states. It's either dead or alive and it won't change when you open the box. Some of these paradoxes are stupid

I think the reason why aliens havent visited us is for 3 reasons 1. They cannot get to us, most of these inhabitable planets are millions of lightyears away and it is impossible for an object to go lightspeed or faster without using an infinite amount of energy so it could simply be that they cannot reach us. 2. They simply have no need, id imagine they have inner politics and a currency system and itd be expensive to travel to another planet millions of lightyears away however if they did theres a big chance since there a millions of planets just like ours theyd have no need to, we would be labeled as not advanced enough to even be worth bothering. We havent even past out galaxy or solar system or even to mars, what good does it serve intelligent life to visit a planet with non-intelligent life when there are millions of others just like ours. 3. They arent advanced enough, the universe is only 14 billion years old and it took earth 4.5 billion years just to put a rover on mars not even a human so if we arent having much luck going to other planets most likely these other planets arent either and you have to take into account our brains grew rapidly in the span of 3 million years, like faster than any other species had ever grown, what if we’re the most intelligent life on the universe, what if every alien is just about on the same stage as us or maybe they just got past the solar system, its interesting to think about

More like how our intentions affect the wave function as an observer, when observed there is a collapse in the wave function, “Brahma sitting on a lotus opens his eyes and the world comes into being, Brahma closes his eyes and the world goes out of being” observation is the act of creation thru inherited thinking

The thing about time travel that makes me question the possibility of it already happening is that what ever diseases and virus’s you have from the future can kill everyone off if you bring it to the past.
My theory on time travel is there is no paradoxes. Think of time like a river if you go back unto the stream and drop a rock the effects of that action will Ripple through the river. But what happens if the river is moving at the same speed as the ripples? Those ripples will never reach the head of the river. Because light is a constant nothing moves faster than light. Our present time is moving forward at the same speed as the altered events are moving forward in the past therefore they will never reach us in the present. The only way to experience the outcome of those altered events is to stay in that time and ride out the wave as it moves forward. This coincides with alternate timelines each moment is a different timeline if you go back even a few minutes and change something it will never reach the present. Because of this a timeline is inaccurate it's more of a Time plane like a infinite piece of paper that stretches across to Infinity. Where the x-axis represents forward and backward in time and the y-axis represents all of the infinite possibilities that can occur between those two times. It might be physically impossible to move backward on the x-axis backward in time but it still might be possible to move on the y-axis to a different spot on the time plane that's still on the same x-axis but merely on a different y-axis. Basically jumping a timeline to where the desired outcome is already a reality
@@Ultimusvivi A simpler theory is that time travel within this universe isn't possible and if you think you have traveled in time you have only traveled to an alternate universe that is exactly like ours but is behind our timeline or ahead of our timeline. You think you are in our future or past but you are merely in their present.
For bootstrap paradox the possible answer will be creating branch in the timeline, when you give the book to the past man you are creating a branch timeline. Same applies to grandfather paradox.

There's a quite simple answet for that question.
If you go to a super market you've never been to, looking for an apple. You could search in the toilette paper aile and the freezers. There is a possibility you might find an apple. But most likely you will find an apple with all the other fruits.
We know for sure, that on a planet like ours life can evolve. So it makes sense to search for life on earthlike planets, rather then on any random possiblr planet out there.

Apparently the human brain is a wee bit narcissistic
I am shocked!
How dare you brain! 🧠
Indeed it is.
I have always had a big problem with the concept of time travel. And it isn’t the traveling part that’s an issue.
Let’s say it’s a given that we can now travel through time. The real problem isn’t WHEN we “land”, it’s WHERE we “land”. In movies, they always assume the point that you’re standing on the earth is the constant. But in order to successfully time travel, you need to calculate exactly what point in the UNIVERSE you will re-appear.
Considering the earth is rotating at something like 1600 km/hour at the equator, and rotating around the sun at 107,000km/hour,and the solar system is moving about 700,000km/hour. Plus the galaxy is shooting through space. In order to do a simple time jump of, say, 10 minutes into the future, you’ll need to calculate the exact point in the universe where your feet will be 10 minutes from now.
And it’s not a straight line, it’s a complex, spiraling, corkscrew path through space. And suppose your math is off by a few feet/a meter, you could arrive half buried in the ground, or floating in the air, or inside a tree, or any number of other gruesome possibilities. The calculations would be all but impossible.
Unless you are time traveling by magic. Then I have no argument.
Oh yeah, I've seen books where this idea got explored in some effect. :D Relative motion is a lot faster than anyone thinks it is. :D
Big brain
You're not taking into account that space and time are one and the same.
@@jwil4905 ok, but...... how does that affect the equations?
This is something I've had issue with since I watched the Time Tunnel in the 60's as a kid. The 2 travelers always fell right on the top deck of the Titanic (instead of say in the engine boiler or the middle of an ocean) or in the cow barn genesis of the Chicago fire, and they even did this separately finding themselves in the exact same place, all purely by coincidence. Too many artistic liberties, all for entertainment value of course, but it got me thinking about this topic.
I think it’s interesting that we always look at possible alien forms as “head, torso, 2 legs and 2 arms”. Nose, big eyes and mouth.
If the universe is so big, the ways forms of life could present itself is also numerous. The chances of extraterrestrial life looking familiar is slim.
We based aliens on humanoid like figures cause that’s all we know, what if they evolved from different chemical compounds that aren’t carbon based, like how ufo sightings don’t have emission like how our jets use fire based engines, maybe they don’t need something like that due to how they’re tech is made.
If aliens exist they look like ants.
I totally agree with this 👌
I agree!!
And the fact that they assume we can see these beings too.. what if we can’t see each other
Here’s a fun fact: if time travel ever exists, than it already and always has existed.
Maybe we'll just never know because you cant travel back in time to whats already happened and just a copy of it or nothing changes physically because rewinding time might not undo the physical changes caused during that passing of time but just the time itself, just like telescopes view past events but in current time
@@mattball420 well technically everything happened in the past everything we hear is from the past because that sound takes time to travel to your ears.
It could be time travel exists or has existed and it's never affected us b.c our civilization doesn't reach that pinnacle.... or it's been achieved and some how our grandchildren perfected how we achieve immortality so the schematics were destroyed so we always come to an outcome of enlightenment
Or!!! Why can't everything we experience right now, in this moment, be the first time it's ever happened and there is no "future" to travel to because we are writing history for the 1st time ever?
I don't think 'traveling ' through time is possible. There are way too many variables involved. Every action a human or any animal makes effects his second to second existence . I did this (cause)& this was the result(affect) & there are 8 billion people on our planet making decisions & taking actions or making decisions & NOT taking actions all day, every day, nanosecond by nanosecond. This literally creates our reality unless, like some sci fi material such as Westworld has speculated, it doesn't. That free will is mostly an illusion & that humans are so predictable that if given the opportunity we would all make the same decisions, & make the same actions over & over & over again with the same predictable results or affects. That there are actually a few moments in each of our lives where we really do have free will & the ability to actually change the outcome of our futures but we mostly blow it because we either don't sense the moment or if do we simply make the wrong decisions. Michael Crichton wrote a book called Timelime a few years before he died that was very interesting. Yes , there was a movie adaptation . No, it's not good or really faithful to the book at all so don't judge this from that movie .Definitely would recommend you read the book though. This is actually possible(in theory) & though not technically time travel it may be the closest thing to it that humans might have a shot at achieving one day.
Time is merely an idea which happens to be very useful as a form of measurement and it’s not even consistent across the universe but it helps us keep track and organize so many things.
That reminds me, I'm late for work!
It's funny that you say time is an idea. If there is a single thing that it's clear that exists outside our brain that we are aware of, that is time. It's like "I think ergo I exist", but actually correct: that "I" is ambiguous because we don't fully know the nature of ourselves. But that doesn't happen with change. If we perceive that things change, something MUST be changing. Probably not what we perceive, probably not as we think it changes, but definitely something changes. Whether it's just "movement" or an alteration of a state. Because if there were no changes at all in the universe, the phenomenon of us perceiving anything would not be possible. The only thing that we can be sure of is that change exists. Time exists.
@JustDoIt12131 Would it then be right to say that time as we call it only exists because we observe change? Change is constant of course, but we have to label and characterize it somehow to place it in our reality. Isn't that where the idea of time itself originates?
Time to me, Is something us humans created to understand where we belong in"time" I believe the cosmos has no time. No beginning and no end. Meaning space has not a beginning and if it doesn't have a beginning it can't have an end. Literally "forever"!
@@Jeff-fd8sc No, time doesn't only exist because we observe change. It's the other way around: we observe it because it exists. Time and change is the same thing.

3. They simply haven’t discovered we exist yet and will find us eventually
4. There are other civilizations but they are actually less evolved than ours and have yet to develop space travel
5. The most horrifying of the options. We actually are alone and intelligent life has yet to evolve elsewhere.

You're watching too many Holywood alien invasion movies assuming that an intelligent species would evolve in a manner that would seek to destroy each other (such as we do currently). These civilisations are here and are actually doing the opposite: Making sure we do not destroy ourselves - as they have advanced enough to realise their mistakes. Evolution doesn't always have to result in destruction of ourselves therefore there will always be so many possibilities of life out there that not everyone of them will destroy themselves.

The problem with that fancy new telescope too is that even if we can look at the surface of a planet on the other side of the milky way for example, that light or image we see is technically that planet in the past because it took so long for the light to reach us. Depending on how far away the planet is it could be 100s of thousands of years in the past and maybe life is blooming on that planet, we just can't see it yet.
and the aliens might have the exact same problem, they se earth but it looks like it did before the dinosaurs, just a vulcanic planet whit no possibilty to sustain life. so for us to find a planet that actualy have life on it, we need to be able to find a planet that is 100 times older than earth that has had life on it for biljons of years or so.

Most of the times when we talk about extraterrestrial life we tend to focus on planets which have similar living conditions as that of earth but that will only stand when we are looking for extraterrestrial life that is similar to ours. There could be other life forms which could function normally in a sulphur rich atmosphere or with winds at 5.4k mph and in that case even bacteria found in another planet are actually aliens.
bacteria from another planet could also wipe us out easily as we'd have no built-up immunity to it. This is the same in reverse i.e. us bringing extinction-level diseases to other planets that to us wouldn't even cause a cold, which is an actual concern of NASA's
That in and of itself could be a paradox. Our instincts and experiences as a species is limited to only earth. It's like what they say about people you see in dreams. You are unable to make up a face, any faces that you dream of will be someone you've seen even in passing. Same idea can be applied here, we are unable to think of another form of life that doesn't share our similarities and environments. Everything we think up of will have a resemblance of either a human, an animal, an insect, bacteria etc, even if you think of a floating white orb, that's how most civilizations perceive souls. So it really can't be answered until we meet something like that. One thing we can maybe say is that advanced civilizations could transcend into a mechanically immortal life, existing as a program or some sort of technology. Even that is ideas from our own species, we are not capable of thinking outside the solar system sort to speak lol.
@@Anten-Isy I get what you mean, but we know for a fact that the universe consists of a finite set of elements that we understand the properties of quite well. If you assume life to be reasonably complex, you need a building block (life as we know it is carbon based for example) from which it is based. Only so many elements / molecules provide the characteristic to be a building block (carbon is tetravalent which means it can bond to 4 atoms at once). Energy needs to be absorbed and emitted in certain ways as well, so I'm sure scientists are looking from a more general perspective such as "what is producing these odd energy patterns, it could be life", rather than looking for a planet that specifically looks like Earth. Carbon and silicon can form solid structures within a certain temperature range for example, so they probably look out for factors such as that. I still agree with the fact we have no idea what alien life might look like, but at the end of the day it is still bound by the same chemical and physical laws of the universe that we are.
As a theist, I consider the creator and the creatures described as angels as extraterrestrials and don't have that feeling that we might be alone. But I certainly can understand how one might feel if the existence of aliens depended on abiogenesis followed by evolution.
What would even be the point of finding bacteria on another planet? Obv ppl wanna find other life LIKE US

The problem with time travel is that you have to go back to the exact location of earth in space at the date and time you wish to travel to. Seeing how the gallery is moving and your solar system is moving with in that and the earth with in that. Pin pointing the exact location and getting to the location in space is just a challenging as figuring out how to go back in time once you get there.
Lets suppose a civilization is advanced enough to figure out how to travel in time.
I think it would be advanced enough to solve that problem as well.
I dont even think it would be that hard (in relation to traveling through time in the first place anyway) as all it requires is enough computing power to calculate all that.
@@EroSensei0 But think of the precision you would need. One meter off and you materialize inside the surface of the Earth.

The fermi paradox is based on the assumption that other "advanced civilizations" would also be willing to expolit and destroy thier planets to build the technology we are looking for to prove thier existence. There is absolutely no logical reason for this assumption. Not every creature is as short sighted as the human species.
and it assumes the smallest chance for each variable, and that is also unlikely
Not to mention that even if there were other civilizations similar to us, looking for life and possibly having the technology, they could have died out million of years ago. They could be so far away, even within our galaxy, that traveling here would be impractical. Like us wanting to send a mission to Alpha Centauri. It's only 4.4 light years away, but it would still take us 6,633 years to get there at our current fastest speed of 450,000 MPH. And even if they knew we were here and just wanted to send us a message, depending on where they are in the galaxy, even that could take thousands of years to get here. It's a false paradox imo. It's the equivalency of some remote tribe 10,000 years ago thinking "We must be alone on this planet, other wise, where are the people??"
Unless it is you who are short sighted and other civilizations don't see it as "exploit and destroy" rather doing what is necessary to gather the resources for expansion.

I lived in a rural neighborhood in the forest in northern AZ as a teen and went on many hikes in the forest. To find artifacts left over from the native or wild west cowboy camps I would have to dig down to find them because they were buried from time passing. Trees dropping pine needles, wind blowing dirt, rain burying things in mud, etc.. I would clear rocks off the area before digging down to find the artifacts. If the artifacts are from the past 150 years or so, why are rocks that are millions of years old sitting on top of the ground above them? Many too big to have been blown there by the wind. Shouldn't the rocks have long been buried in time? I would find large and small chunks of petrified wood sitting openly on the forest floor, even though it's surrounded by pine trees. Shouldn't it have been buried under pine needles and everything, given how old it is? Some you would think someone just put there a week ago. How are so many rocks that are millions of years old sitting openly on the top of the ground, above things that nature buried in the past 100 or so years? Not really a paradox but something I used to wonder as a teenager.
It is possible that the Younger Dryas impact event very suddenly melted half of the world's glaciers very abruptly. The ensuing flood in your area was a literal ocean of water pouring down southward, tearing up the entire landscape, washing away entire geological strata, exposing very old features.

And in Photoelectric effect the classical wave theory fails and give rise to it's partical nature and also give idea to dual nature of matter

UA-cam has a video that highlights the robustness of life in the universe as only a very small part of its overall time line. Like akin to only a few seconds in the life of a human.
Could be. The numbers are so vast though - so inconceivably vast that the sheer statistical odds is that many thousands of civilizations have continued - maybe in ways hard to imagine. Perhaps they disappear into their machines - occupying virtual spaces instead of actual ones. Maybe physical biology is just a baby step of the evolution of intelligence. There is so much we don’t know it’s difficult to even frame the questions. It truly is mind boggling.
Kevin Brooks that's interesting . Once you wrap your brain around the incomprehensible size of the known universe & the time frames involved its an idea that's started to gain some traction in recent years. You know there's really only a couple of movies that takes this concept & runs with it & that's Forbidden Planet & the original Alien especially but just as a standalone film without considering the prequels at all. What essentially happened is that ship really just stumbles into a scene from some kind of cosmic nightmare that is supposed to have played itself out a long, long time ago. Unfortunately for the crew of that ship one small piece of that nightmare is still alive. Finding the remnant of some long dead civilization is, in many ways, more realistic than straight contact and Alien really capitalizes on that fear of the unknown factor better than anything still out there
The other thing is we search for signs of our life and technology. An advanced civilization could use a totally different system we don't have the technology to detect. Not to mention when it comes to the universe distance is the biggest problem. Who knows 200 years ago maybe we were getting signals from a civilization that took millions of years to reach but the planet is long dead.

I’ll do it.
Countering the Fermi paradox, if you look at the time line of the earth's existence and specificaly the total period of time that human life has existed on earth, it is a tiny blip in time over the time line of the existence of our universe.
So potentially we may have came to existence after other intelligent life ceased to ocupy our local area of the universe, or other intelligent life may not be evolved yet locally to us, given how big the period of time the universe has existed so far and likely to continue.
The Fermi paradox is like the Drake equation. Since there is only a single planet we know of with life on it, any other numbers we use in our formulas become an example of GIGO
Many of these are the exact same paradox expressed with different stories/scenarios to explain the elements. The root of the paradox is "just how does time work" to which much of science is preoccupied with figuring out, breeding hundreds of thousands of interesting questions.
Time is just another physical spacial dimension. It is pretty simple to understand. I can say scientists already know this, for a good while now. It is just regular society who still is uneducated about it.
@@fernandomartinez4486 sadly this is objectively untrue.
At any point in history scientists largely believed they understood time so the changing information proves they did not. When mankind genuinely has a solid understanding of new knowledge, it empowers man to do things they couldn't do before.
The existence of these paradoxical questions and man's lack of empowerment to do anything new with time, demonstrates that scientists do not yet have a good understanding of how time works.
@@fernandomartinez4486 You couldn't be more wrong.
One problem with communication over interstellar distances is just that. The time it takes for radio signals to travel from one star to even the nearest makes it very impractical. Also, the ability to detect signals that have dispersed through space and over the inference in space makes it exceptionally difficult. Look at the Viking probes. If we didn't know they were there and exactly where to point our radio dishes it would be virtually impossible to detect their weak signals. Most civilizations out there probably use some focused beam tech to communicate which would make it almost impossible to intercept unless you happen to pass through the beam. So unless they come to our planet, it's unlikely we could ever find them by looking for random radio signals.
This is a problem for us and our tools... what if some aliens have a completely new way of comminucation, a 3 thing. That we can't wrap our minds around

A sad example of this is there was a signal received that translated to a distress call for help from a very distant star that went supernova. However, it was already too late by the time it was received and there was nothing we could have done as this star was millions of lightyears away and although the supernova was viewable from Earth, it took just as long for the light from the supernova to travel for it to be seen from Earth. The distress call did come first before the supernova was observed happening but, even if we wanted to help, it was already too late because of the distance.

There really is no such thing as a Paradox, the universe is logically consistent and anything else is either a fabricated "what if scenario" or lack of clarity.
Or because we are in a simulation
@Pewdjepje cute but no. Go watch pewdiepie and escape reality you weeb
I agree. None of these are concrete paradoxes that are completely unexplained. They are all just thought experiments or “what if’s.”
well actually the universe is chaotic, we're the one who wants to make sense of it and make it consistent

Perhaps we are living in a simulation. This would explain why there would only be one inhabited planet in our universe despite the astronomical odds against that possibility. It would also explain why light behaves like a wave when nobody is watching and like a particle when someone is. It would also explain why quantum physics are so strange and different than normal physics - because the beings running the simulation have to impose limits to prevent us from being able to determine that we are indeed in a simulation. (Limits like the our fragile planet with limited resources, our delicate bodies, the hostile environment and vastness of space, the one-way linear flow of time, the speed of light, not being able to find any black matter despite it making up most of the universe, never being able to reach or see anything beyond 46.5 billion light years from Earth or beyond the event horizon of a black hole, or anything smaller than an atom, only being able to experience three dimensions, only a rudimentary understanding of how quantum objects exist in multiple states, quantum entanglement, etc., etc.)
This is cool 😎
True, the one we seek, is the one who sees, who is the creator of the simulation? Perhaps our spirit creates the simulation for are selves to learn spiritual evolution (love) at a faster rate, or perhaps the simulation is just a game for us (entertainment)

Here's something that seems like a paradox to me, but could probably be explained by a physicist: Imagine a totally dark room with a lamp. You switch on the lamp and now you can see all the room. You can see because the photons bounce off (reflect) all the surfaces in the room. Now turn off the lamp and it instantly gets dark. What happens to all those photons bouncing around in there? Why do they just instantly disappear?
Probably a stupid question, but it bugs me.
speed of light
They get absorbed by the walls, when a beam of light comes in contact with an object some photons get reflected and some get absorbed, but if your room was somehow made of a completely reflective material and you were wearing that same material then the room would stay lit. But we dont know of any such material yet
So if the walls of the room are mirrors then the light would bounce around longer then in a room with black walls, but we are talking about insanely short amounts of time here because light is so fast and youd never be able too actually see the difference
They don’t disappear. The speed of light is just so fast that it appears instant.
Even if you were 1 km away from the light source. That will be 1/300 000 of a second.
Its matter. First you must ask yourself where are all the photons coming from? From the light source they are blinking into existence. So if photons can appear into existence they have the ability to disappear just like they appeared in the first place. In a 4d universe, objects will appear and disappear to our eyes because our brains cant process what a 4d object looks like. So maybe theres a bigger picture to what light/photons actually are. We wont see until we reach the speed of light.
There may be a flaw with schrodinger's cat paradox. The scientists are assuming that the cat won't interfere with anything inside the box. The cat is unpredictable.
your missing the point and the paradox, my guy
I also think scientists are assuming that the cat won’t interfere with anything inside the box. The cat is unpredictable and may try to escape, scratch the box, or tamper with the apparatus.
This may affect the outcome of the experiment and invalidate the premise of the paradox.
In fact, some interpretations of quantum mechanics suggest that any interaction or observation, even by the cat itself, could collapse the superposition and determine the fate of the cat.
The Von Neumann-Wigner interpretation does talk about this. The cat's state was already determined before the observation; it's just that we didn't know until we looked. I could be wrong though

How to save someone life without creating a paradox in time?
Lets assume that we travel into the past (lets say 5 years) so save someones life that died 5 years ago.
How can you save that persons life without creating a paradox in time?
Stupid as it may sound, its very simple:
Save that persons life, without letting anyone know that they didnt die.
The events traveling their death have to transpire the same way, and the person has to remain "dead" until you reach the point in time you travelled back from.
After that the person can reveal themselves as everything hence forth wouldn't create a paradox anymore, because you never reached that point in time before travelling back in time and up until then, everything had remained the same as you have known.
you could either simply bring the person "back to the future" which would be the most failsafe way of doing things without creating a paradox, or make sure they dont effect the timeline in any way during the time of their supposed death.
As long as the records stay the same up until the moment of time traveled back from, nothing changes.
this sounds logical to me anyway.
However, there is one good counter argument though:
Time is not owned by humans, meaning, just because we dont know about something happening or not, doesn't mean the universe isn't aware (as stupid as it may sound)
The person that died in the original timeline did not disappear from the universe.
the particles the person was made of still remain in the original timeline and in one way or another effect the original timeline, as minuscule as it may be.
and the absence of that effect of the timeline may cause a paradox in itself.
... or not, who knows.
this shit is so complicated, ill go watch some mark wahlberg movie
It’s valid …Only if the person was dead somewhere where you was never find.
Like that when you save the dead person the things will happen as it has always happened.

Damn bruv I didn’t understand 80% of that, do u read the dictionary before bed or something?
@@vola7342 I bet he reads 2 for good measure
Well I don't really think so. It's like psychology and let's say geology. Together they all make humanity but they are both fields of study that have nothing to do with eachother. We were able to build a floating laboratory/city in space before we explored 20% of our own ocean. We put men on the moon before we realized that smoking kills people. Alien life more likely than not will share nothing of our own physiology, so technically we could advance on the second confusion without touching the first one. If you want to look at everything in the lense of biology then yea technically we need to figure out how cellular life forms so we can expand our knowledge about what the possibilities of life forms are, but without first meeting something from out there we would have nothing to work on, only theories which without evidence wouldn't stand. There is a moral question in your example however, should resources be allocated to studies which don't really give any real benefit when we could allocate it to research and development of technology or medicine that is useful for the betterment of society. Isn't it a little cocky that we dip our feet in space before we get our life expectancy to atleast an 80 everywhere ? So your point stands in a moral/ethical light but scientifically it shouldn't interfere one and other.
You also have to consider that reversing in time is impossible as a solution, and the only way around it is to enter a near perfect copy of your universe before times progresses to the point you want to enter. It is far more logical to assume the system we exist in lacks the ability to properly rewind, going forward has already been proven to exist but not backwards. Also this idea is supported by thermodynamics, the reversal of the system would violate the common laws we know to exist.
The only feasible way to time travel into the future is to wait it out ... in a conscious or unconscious state ... in reality that's not time traveling ... let's see this proof
I think we just can’t travel backwards fast enough. Like trying to go down an up escalator or up a down escalator, we can sometimes go faster than the escalator and make it off going the opposite way but time moves forward too fast for us to move backwards
thermodynamics only exists under our presuppositions of time. if time were a plane instead of a line, then thermodynamic systems would be only the areas of that plane that flowed in a straight line. although it would only violate the second law
@@dumby8918 Nah bruh, if you travel at very close to the speed of light you can go forward in time like 500 years in a few minutes. Einsteins train.
The double slit experiment has some misconceptions. This used to fascinate me before I learned the true nature of the experiment. When they say “observing” changes the result, they really mean when the particle is being sensed by our equipment. They fail to clarify that the equipment used to “observe” actually has some Interference with the experiment.
Well is apparent I think that just observing something with the equipment is having some kind of effect. Finding out why is the problem.
this is not correct... ''Observation'' in quantum mechanics is NOT concerning detector input.

There is a time travel paradox that it seems no one ever covers. It begs the question ... Can you travel into the future and meet your older self? You know that unless you die, you will become older at some future date, and if time travel should be possible it seems to be a reasonable thing to do. But what if you decide to never return to your initial time of travel? How can you ever become the age you expect to meet at that future time? Yes, you can go back (if this sort of travel ever exists) but you don't have to.
I wish my younger self could visit me now (age 78). I could warn my younger self of all the stupid things I did and try to convince younger me to be smarter. Would I then wake up in a different situation - because of the better decisions my younger self made - because of the warnings? I wish.

No, that's just dumb as shit.
I think the problem with the double slit experiment is not the photon. It doesn't care if it's being observed. The problem is the observer. We are not capable of observing paradoxes. So when we make a deterministic observation of that this photon is up to, from the observer's POV the wave collapses. In according with the theory of parallel universes, the interference pattern is still there, we just don't see it because making that observation, coupled with our inability to observe paradoxes, only allows us to see one outcome.
I like that thought process
I agree with you, only change I would make is that I personally don't believe there is a paradox. We only see a single outcome because we are apart of this universe. I think its probably much more simple than we are making it out to be. I think that anything that can happen does happen in another reality and when we observe the photon we are interacting with the photon causing it to show the outcome that was always going to happen in the reality of the observer. In fact the experiment may prove the exsistance of fate.
Correct
Nice comment
But what is the mechanism that causes the wave function collapse?
A “deterministic observation” in the context of the double slit experiment should have no effect on the photon. In fact you can leave the measuring apparatus in place and just scramble the results with a computer preventing which way knowledge and the wave function is reestablished.
I think the key here is when you say “from the observer’s POV”. Reality itself, as in a space/time matrix with locality (objects with actual location relative to the observer that are collapsed out of just potential ) maybe manifested by a sublime interaction with a form of consciousness more fundamental than space/time.
@@LiteShaper1 Its the interaction of the detector that causes the waveform collapse. Well you can believe what you want but I don't personally believe a consciousness is required. Science had to at least consider the possibility a hundred years ago when quantum mechanics and the double slit experiment were still young but the vast majority of scientists have long since moved on.

I’ve heard it said that time doesn’t really exist, it’s something we invented to give us familiar reference points. But then how do you explain aging? Everything gets older. So time must then exist? But what time is it in the void of space? So time only exists on planets, and only on planets with intelligent life? But that supports the idea that time is only an arbitrary reference point that doesn’t really exist. And how would this affect “time travel?” How could we “go back in time” if it doesn’t really exist? And where is/was the starting point of time? If there’s no universally agreed upon starting point, how do we calibrate it for time travel? And whose clock do we use and how/when was it calibrated and is it completely accurate over multiple millennia? And what about “leap year,” times zones and daylight savings time? I need these answers by tomorrow.
Robert A. Heinlein wrote two of the best time-travel stories - "-All You Zombies-" and "The Door Into Summer". Carl Sagan listed "-All You Zombies-" as an example of how science fiction "can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader".
On the Fermi paradox, is there anyone who may have suggested the possibility that an alien race could have advanced beyond the point of individual existence and has become a type of collective which exists beyond a physical body. A sentient energy so to speak.

Says one scientist to another, "How do you [ possibly ] know the timeline has not been altered?"
The solution the observer paradox is that when observed photon interacts with the photon received by our eyes changing its behaviour , this is also the reason for the wave function collapse and heisenberg,s uncertainity principle .. Now , where's my noble prize ?
So my theory on the bootstrap paradox is that when you go back in time, you're creating a loop and time is no longer linear and a loop has no beginning nor end.
have u ever played ocarina of time, it has a very famous song in it that was played to u by and old man who said a kid played it for him and its stuck in his head and will never get it out, and when you go back in time and play it for him and he loves it and says he will play it forever, who taught who the song?
Ask john connor 🤣🤣🤣
Time was never linear to begin with
The universe has the built in property in the present such that time travel cannot change those events. You create a time loop. It will always be just out of reach and you have to make the same decision. Also, in a time loop if something has happened in the past, it has always happened (e.g. you did not change it).
But, the universe's built in limitation does not take away from free will. Conduct your life to allow for possibilities if you ever suspect you might be in a time loop.
The movie "Triangle" does the time loop well. Although in that movie, there is another copy of "you", present "you" cannot interact with past "you" in any way that will change the future.
I believe time loops are finite and they are usually short time periods. You probably won't realize if you are in a time loop.
Time isn't linear. We merely experience it in a linear form. Most likely due to our physical limits
One thing is for sure. Once we find out even one answer from these questions, it will change our outlook on life as we know it.
Well with the Hamlet paradox and time travel in general, when you go back in time and change something, that creates almost a branch in another direction, it creates a different timeline.

2:35 Saying there is no life, because we haven't found proof, is about the most naive thing a person can think. I will go with Sagan on this one.
I heard a quote once, something along the lines of ‘we are either alone in the universe, or we’re not, and both are terrifying’. If we destroy this planet through nuclear war or mass extinction. We could potentially be wiping out all consciousness in the universe. The universe will no longer be experienced, the universe will be silent again. A spectacle of a show to an empty theatre.
Well, I think that we are not the only living species in this massive and immeasurable space, and here's why. It is estimated that there are more than *100 billion planets* in our Milky Way galaxy alone. It is also estimated that there are more than *200 billion galaxies* in the *"observable"* universe. So if there are 100+ billion planets in one galaxy, how many planets do you think are there in 200+ billion galaxies? Now, we never sent probes to gather data on all those planets, so why would we assume that we are alone in the first place? That being said, I think there is a very high chance that there are lots of civilizations out there, but we are just too far apart to even make contact. And if these civilizations are too advanced, why would they seek us out? We are currently a type 0 civilization. Any civilization above type 1 would never care to contact us because we are inferior to them. At the end of the day, we really have no idea how immense the universe really is. There is a huge probability that there is an infinite number of galaxies, since it is said that the universe keeps on expanding. So, can we really say that we are the only living beings in this vast and unexplored unknown that is the universe? Are we really that special? Don't forget, we are only talking about the observable. We still don't know what lies beyond the observable.
Or there are other worlds Just like ours but we can’t reach them ?
@@prod.heysus2838 There are endless planets just like ours and even better ones, and yes, we can't reach them because they are light years away. The problem with NASA is that they keep on looking for extraterrestrial life on Earth-like planets only. They keep on assuming that if life exists out there, it has to be on a planet that has the same conditions as ours, which is very wrong. We never know if extraterrestrials might be able to adapt to harsh environments that us humans can't. Maybe ETs don't need sunlight, oxygen, and water in order to survive. See, scientists always seem to hold ETs to human standards, which is a big misconception. Always think outside the box regarding interstellar space, because the reality inside our solar system is so much different from the outside. That's why science is always evolving.
The quote is from the author Arthur C. Clarke.
“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
The Observer's Paradox / Schrodinger's Cat Box always struck me as less an exploration of quantum states and more an exploration of the learning limitations of our observation-based method of scientific inquiry. Those who take the paradox literally are suggesting that reality doesn't coalesce into certainty unless it is observed, but doesn't this suggest some sort of nigh-magical power on The Observer while simultaneously undercutting the idea that the universe operates based on consistent, demonstrable principles? After all, if we believe that reality only becomes fixed when it is observed we imply that all unobserved locations and materials are inherently unpredictable and could do or be anything until an observer comes into play -- the irony being that, if the unobserved universe were truly so fickle, we'd have abundant second-hand evidence of the chaos it would unleash, which we don't. This kind of thinking, it reeks of the kind of limited humanity-centric medieval mindset that gave rise to ideas like Spontaneous Generation, Humors, and Miasma. The idea that the cat exists in both states at the same time is ludicrous, and I strongly suspect that all the "serious" scientific theories that stemmed from it will ultimately be set aside as our observations and predictive modelling improves.
The Observer Paradox, as far as I can tell, is just an outlet for people who never fully wrapped their heads around the early childhood concept of object permanence. Prove me wrong.

I'm sure I just don't understand it, but I dont see how not knowing if a cat is alive or dead affects the state of the cat. If I flip a coin and the coin lands on the counter and I cover it with an opaque material without looking at it, the coin is still either on heads OR tails, irrespective of its statistical probability before the coin was tossed, or my knowledge of the result.
This is a better definition of shrodinger or whatever his name is
It doesn't affect it and can't. The so called paradox is childish. Just because we don't know, it doesn't make it a paradox. If my friend lives half way round the world, I have no contact with them for a year so don't know if he/she is dead or alive, it's not a paradox, I just don't know!
All paradox are are simply our inability to comprehend, failures in our understanding.
Fact would not include any paradox.
We invent paradoxes! Is time travel even real? Yet we invent a paradox on something not based in fact but mathematical equations, human constructions!
The only valid paradox here is the double slit and like the others I think it's due to our limited/false understanding.
@@waylandsmith235 The cat paradox is totally valid, it's only very poorly presented here.
The paradox is very poorly explained. The gist is that what you describe for the coin doesn't apply to a particle decaying. Its state is undetermined until it's observed. Not undetermined in the sense that we don't know, like for the coin, but actually undetermined, like a coin that would stay in the air and never land until you'd look at it. Or rather that would land on both sides at the same time and only "pick" one when you look. That is established at the particle level, but the paradox is : what if the state of the particle had consequences at a macro level, like for instance a cat dying or not depending on whether the particle has decayed or not. We know that the particule is in an undetermined state having both decayed and not decayed, until we check. So, is the cat as well in an undetermined state, both alive and dead until we open the box?
I imagine that if there are other civilizations out there they might be far beyond what we have contemplated. They might view our civilization as simply way to primitive to allow us to know they exist. I view one of the problems with humans is our ego.
It's alot more likely there mostly just very primitive and stupid were the only truly intelligent life form on this planet how many other life forms are there .. i would assume most aliens would be primitive based off thst .. your opinion seems to be biased and based off what u want ... because of movies and stories ... and not a actual evaluation of the odds ... the only thing we got to base other lifeforms off of is what we got on this planet ... and everything here Is stupid other then use ... there probably is more advanced species .. but it's high unlikely that there is many species 1000s of years ahead of us ... intelligent life as we know it took billions of years to happen ... the universe is very old but it takes a very long time to develop life and planets ... the majority of life out there is realistically just bacteria
What we used to learn in schools makes us think that the universe is just as simple as a note written on a paper but it's just so so so complicated
If information cannot be destroyed, does this mean every thought a being in the universe ever had still exists in the universe? And if you think about something that physics don’t allow, does it exist because someone thought about it?

The only answer to the bootstrap paradox that seems to make sense would be that if you went back in time with that copy of Hamlet, the instant you got there would start a new time line branching off the timeline you started on. Both branches would still exist but your conscious mind would be in the new branch. In that case, Shakespeare wrote Hamlet, just not on the branched timeline you created when you went back.
and if you gave billy a book printed in modern english he'd think you'd given him something in chinese, or as useful to him as that...
Hold on, question about the observers paradox
So the whole cat experiment went through and you didn’t know the cat had died unless you look in the box. How does the change the fact the cat died? Things constantly happen without us knowing, how does us not seeing something or not knowing something make that thing not happen?
Yes and if you also consider probability’s of this happening are extremely high you can take a very educated the guess and basically know for sure this cat is dead therefore you know the answer before you can confirm
Exactly. Like when neptune was discovered by using mathematics. Astronomers knew that there was another planet affecting the orbits of some of the planets. They did the calculations and pointed their telescopes where the math said it would be and there it was. Neptune. So by the logic of the observers paradox Neptune did and didn't exist until it was observed... but yet it was surely affecting other planets... just doesn't make sense.
Dont listen to this paradox is dumb

In this video, the paradoxes are versions for simple-minded people just for some WoW reactions. But if you watch the physicists version of these paradoxes, they'll get into much detail and keep you away from the popular misunderstandings.
Wait for twenty years. By that time the cat will have died of old age if it hasn't already starved to death. Or just take a whiff around the area of the box. If the cat is dead, you'll know.
Given that we still have basically no idea whatsoever how we jumped from lifeless molecules to living cells, you can't really put any stock in estimated probability of other life. It's literally the most important part of the equation. Doesn't matter how many planets could theoretically support life if it's never created in the first place (not to mention the millions of things that have to line up just perfectly for it to evolve into anything sentient, then to something as advanced as we are). It's not even a tiny bit surprising that we haven't found other life. There may not be any. Fermi isn't a paradox at all.
I wonder, with time measurements being so astronomically tiny, I wonder if you end up traveling back in time, and accidentally changed something, with all the timelines that would likely branch from that alone…. How would you honestly reach the exact same timeline you were on before? It would nearly and seemingly be impossible, right? Which would assume the point that anyone who tries to go back into your own timeline are likely to travel into an alternate timeline that you think is yours… and probably just isn’t… or can someone explain to me why this wouldn’t be the most likely scenario?
One day I’ll be able to answer your question.
Maybe going back in time is just your future you haven't been to yet.
Take this with a pinch of salt, as it's heavily my own interpretation from a massive amount of sci-fi and physics consumption and a nice dose of nihilsm, but here goes:
The issue here is making it human-centric, as we humans are so prone to do. A better interpretation is not that you are "creating" a timeline, but simply fulfilling the conditions of a timeline that already existed. A parallel universe isn't necessarily running in sync with ours on an equivalent timeline, they already have their own timeline with preset events, just like ours. Due to the infinite interpretation of Multiple Worlds, it's inevitable that there will be a universe that's so alike to ours but behind in appearance, that you, as a human who has to interpret things in relation to themselves, would assume that it's your own past. But it's not. you haven't even time-traveled at all, just been moved to a different location in a different universe. You aren't changing anything, because it was already going to happen anyway. You're not on your "own" timeline, you're in a parallel universe that you were always going to reach. "You" don't have anything to do with it, it was always there, you were always going to go there, and do whatever it is that you do there. Seems like you were already there with the part about "think is yours and probably just isn't", so kudos, you're on the right track, but you need to apply it to the entire scenario in a less personal interpretation.
As for returning, if you have the sensational technology that allows you to dimension hop in the first place, you'd hopefully be able to use it to hop right back. As you rightly surmised, it was never "your timeline", just *a* universe - a location that still exists, and would continue to exist, for you to return to. In fact, you already did or didn't return, and nothing will change that because your original universe already has a set timeline, too. You might even hop back in on a different point in time, but that already happened if so, and we've just never gotten word of it. Think Star Trek Prime Directive, but for time travel (which is also a thing they have).
A sort of half-way thought to use is that a timeline is only relative to you, and what you experience. YOUR past is a fixed experience, but so is your present and your future. Everyone else is experiencing the exact same phenomenon. For you though, the future doesn't exist yet because you haven't experienced it. Same for them: if you tell someone that you have come from "the future", you haven't, because that future does not exist for them, what you have come from is YOUR past. Is this more confusing? Maybe, but it's the best way I can rationalize it to work with our self-oriented POV. Naturally, we can't work out all these things beyond theoretical speculation anyway, because our 3D human brains can't interpret time as an axis.
TLDR: Maybe you could go into "the past", but if so, you've already done that, it wouldn't be *the* past, and nothing would change. Thanks for attending my TED talk.
@@mudokon1004 yeah really. the concept of causality violation is.. unknown... and thus the entire dialogue is moot as it's speculating on physical laws that.... are impossible to experiment with. Thus the entire concept of time travel paradoxes is little more than fantasy.
@@mudokon1004 cringe
I think it’s as hard for any as it is for humans to get to and travel space.
We’re also animals.. and this type/scale of thinking is only unique to human beings..sure there is other animals on other planets but self aware animals like us gets less and less likely, imo
The cat paradox always makes me laugh. No, the cat isn't dead and alive at the same time. Just because you can't see it it doesn't mean it's in both states. It's either dead or alive and it won't change when you open the box. Some of these paradoxes are stupid
Look at that, Catalin Fuca from the UA-cam comment section solved quantum superposition
@@lukesmith6674 the cat paradox is used as an example for how quantum particles behave. But what I'm saying is that this cat paradox has nothing to do with reality and is a stupid example. Not how reality works. Only at subatomic levels and it can't be upscaled
@@DarkNightLight68 I I didn't solve the quantum superposition. I did solve the cat paradox. You're welcome
@@HakaiKaien if I were to slap you or not ,I'm creating two realities ,just like the cat paradox ...it can happen or it doesn't really matter because you won't open it to care or see ,just like me not slapping you
@@sybergaus you're not creating two realities. Reality is what actually happens and the other is just a proposed outcome that COULD happen. Only one becomes a reality. And it becomes a reality when it happens.
for your information it was Sir Ramanujan who gave the string theory

If these are the “paradoxes” that keep the worlds most brilliant minds awake at night, I am WAY smarter than I realized.
lol
These aren’t even paradoxes, the grandfather paradox part doesn’t even explain it at all
Don't worry this video producer really really really dumbs down these paradoxes to the point I don't think they get them
I was gonna say - he butchered all of them. Anything for a click these days, even talking out of your ass about a subject of which you have zero comprehension.

I think the reason why aliens havent visited us is for 3 reasons
1. They cannot get to us, most of these inhabitable planets are millions of lightyears away and it is impossible for an object to go lightspeed or faster without using an infinite amount of energy so it could simply be that they cannot reach us.
2. They simply have no need, id imagine they have inner politics and a currency system and itd be expensive to travel to another planet millions of lightyears away however if they did theres a big chance since there a millions of planets just like ours theyd have no need to, we would be labeled as not advanced enough to even be worth bothering. We havent even past out galaxy or solar system or even to mars, what good does it serve intelligent life to visit a planet with non-intelligent life when there are millions of others just like ours.
3. They arent advanced enough, the universe is only 14 billion years old and it took earth 4.5 billion years just to put a rover on mars not even a human so if we arent having much luck going to other planets most likely these other planets arent either and you have to take into account our brains grew rapidly in the span of 3 million years, like faster than any other species had ever grown, what if we’re the most intelligent life on the universe, what if every alien is just about on the same stage as us or maybe they just got past the solar system, its interesting to think about
Technologically advanced, capable of space travel, aware of other habitable planets, on the search for one to invade...
What if we're the aliens 👽
@Dakoda Fisher he is saying what if we are the most intelligent life forms in the universe, and we show up to a planet one day and find less civilized beings freaking tf out when we arrive. What if we are ahead of all other life?
@@santorashane we might be. We also might be the only intelligent life forms in all of existence, well at least on the physical plane.
@Dakoda Fisher we are aliens to aliens tho
@@santorashane He is making a good analogy that Humans are no different than our Extraterrestrial visitors. We are all just Denizens of the Universe that all living beings call home.
There are theories of how we are aliens and fled to this planet after we destroyed our planet via nuclear warfare
The fact that time travel has so many paradoxes is enough to believe that it probably isn't possible
Iterations
"It probably isn't possible"
Or we humans are still not smart enough and lack the technology for that kind of stuffs
Or there's a higher power above all of us
@@bomcstoots1 ?
I've heard that if we can manipulate gravity we can travel through time. So it's just a matter of time(no pun intended) until we achieve it. Of course I have no idea if this is true I'm one step above a monkey.
If you say you want to develop time travel just tell yourself that if you ever develop time travel you will come to this exact time
Didn’t happen did it, guess you won’t do it
The double slit experiment is not a paradox. It's an example of how the wave-like properties of particles affect the environment
More like how our intentions affect the wave function as an observer, when observed there is a collapse in the wave function, “Brahma sitting on a lotus opens his eyes and the world comes into being, Brahma closes his eyes and the world goes out of being” observation is the act of creation thru inherited thinking
The paradox is that these sub-atomic particles behave unlike matter on a macroscopic scale.
@@FrenkieWest32 it's not really a paradox for an item to not share the properties of its constituent parts
@@AdrianLParker a paradox is a seeming contradiction or an unexpected concept. So yes, it is. Quantum theory, while very reliable, is unintuitive.
@@FrenkieWest32 but it's not a contradiction for an object to not share its constituent part's properties. That happens all the time in chemistry for example.
The fermi paradox assumes that we haven't been visited but doesn't take into account visitations with no contact.
for the bootstrap paradox,its paradox is solved by assuming that once this happened a whole new different timeline was created which was different from the timeline in when u bought the book in the store,hence a whole new future was created
I’ve watched several space videos for a very long time and I am so thankful and lucky to have found your channel with the best most amazing videos ever, has information explained and how everything works is the best and your commentary fits outer space perfectly with the best scenes real images of our universe and beyond. Thank you so very very much for everything you do.
The thing about time travel that makes me question the possibility of it already happening is that what ever diseases and virus’s you have from the future can kill everyone off if you bring it to the past.
Unless in the future technology is so advanced there are no diseases 🤔
@@Th3lov3virus thats a potential theory🤷🏽♂️. If that were the case theres hope for the future.
My theory on time travel is there is no paradoxes. Think of time like a river if you go back unto the stream and drop a rock the effects of that action will Ripple through the river. But what happens if the river is moving at the same speed as the ripples? Those ripples will never reach the head of the river. Because light is a constant nothing moves faster than light. Our present time is moving forward at the same speed as the altered events are moving forward in the past therefore they will never reach us in the present. The only way to experience the outcome of those altered events is to stay in that time and ride out the wave as it moves forward. This coincides with alternate timelines each moment is a different timeline if you go back even a few minutes and change something it will never reach the present. Because of this a timeline is inaccurate it's more of a Time plane like a infinite piece of paper that stretches across to Infinity. Where the x-axis represents forward and backward in time and the y-axis represents all of the infinite possibilities that can occur between those two times. It might be physically impossible to move backward on the x-axis backward in time but it still might be possible to move on the y-axis to a different spot on the time plane that's still on the same x-axis but merely on a different y-axis. Basically jumping a timeline to where the desired outcome is already a reality
@@Ultimusvivi Omg I love this theory of yours.
@@Ultimusvivi A simpler theory is that time travel within this universe isn't possible and if you think you have traveled in time you have only traveled to an alternate universe that is exactly like ours but is behind our timeline or ahead of our timeline. You think you are in our future or past but you are merely in their present.
For bootstrap paradox the possible answer will be creating branch in the timeline, when you give the book to the past man you are creating a branch timeline.
Same applies to grandfather paradox.
still who actually wrote hamlet?
