He is ultimately describing different perspectives within a universe. But ultimately all time flows the same. It just appears to move at different rates. Imagine a race where everyone starts at the same time and ends at the same time. To each racer it feels as if time is at normal speed and looking at everyobe else they going slow. But in reality they going the same speed just the time it takes light to travel from them to u you and have increased your distance from the origin of where they were.
@@sicsemperevellomortemtyran3526 so at what point did the big bang occur, at different points in space? Are u suggesting there was different points of a massive expansion and explosion? And at what point dose the universe end? If the universe is frozen and fusion is no longer occurring because the universe expanded too much, are there then people still alive somewhere. Clearly not.

Also, if a photon doesn't experience time because it travels at the speed of light, its "experience" is just one eternal moment that includes all of the past and future. The paradox of that is mind blowing, because we observe it as travelling through space, which implies time. This relative nature of "time" is one of countless things that prove that all of existence is eternal.
Ive thought this many many times and commented it, maybe time doesn't exist at all and its consciousness that creates the illusion of it, everything you are in terms of energy, existed long before you and will continue to exist long after you're gone, but only if you think of time as linear, if no energy can be created or destroyed then everything is just here and always has been, without a mind to perceive anything what does it even mean? and if we are made of the same stuff that exists everywhere and we're conscious then the very system we came from has the components of consciousness therefore must also be conscious to some degree right?
@@mickyr171 Time is simply the illusory perception of the movement of "form" (I use quotations, because "form" is illusory as well). I think it's important to clarify the term "illusory". When we say it's an illusion, that doesn't mean it's not happening and isn't real. The illusion is real in the sense that it's a necessary part of experiencing anything. We just call it an illusion, because it's ephemeral and in a constant state of change/transformation. In a sense, it's a paradox. Here's the interesting thing, in my opinion. I think consciousness is illusory as well, but it's the only thing that allows an experience of anything. Anything existing without consciousness is no experience at all, but consciousness is ephemeral and transforms as much as forms do. Basically, nothing in existence is static. Therefore, all of existence and experience is an illusion, but the illusion (constant transformation) is a necessary part of existence. Everything is basically nothing, one thing, eternal, and infinite, and it experiences itself as a constant transformation of embodied forms and consciousness.
My favorite actually comes from a video game, with an alien race that ends their conversation with you with "May your offspring not be destroyed." Mighty magnanimous and awfully specific of them, wishing for my children not to be murdered and all.
I once heard the block universe described as the "view from nowhen" and I still think that's once of coolest phrases. The graphics in this video did a great job of showing it along with the concept of time sliced at different angles. 👏
It is an error to visualize the Big Bang as an explosion you watch from afar because that presumes a vantage point that is literally outside the universe and therefore nonexistent. This entire video makes the same error but about the universe long after the Big Bang.
@@PaulthePhilosopher2 I'm with you on the big bang but I think the "view from nowhen" is only an error if you consider it a physical possibility and not simply a helpful visualization of the 4th dimension.

Agreed. The past exists while the future is probability. Someday, we can likely time travel to the past, but if we attempt to time travel to the future, we would only be viewing the most probable future anticipated at that time. This explains why most prophesies are wrong.

my thoughts att first was he was gonna tallk about past present and future exsisting all at once but not exsisting ? lol i was gonna ask well when did it start and stop i mean we have or present time and our parents have there present time like our kids and those who came before how can all that be exsisting at the same time through generations where many past present and futures are happening via every body

@Bernd DasBrot is that not true? The past existed. The future will exist. This is simply what a tense is in language, defined by its own elements, its quite an engrained concept. You think there is an 'outside of time' yet there is no such place. Even if a dimensional spacetime, such assertions to "the past still exists" are only analogous and defined by tautologies.

Block Universe does make a lot of sense. If you think about it why would the past be erased? Why do we only have a memory of the past and not the future? Incredible
"If you look at something from a different angle, then you're looking at it from a different angle." Ah yes, if only every everyone was smart enough to realize this. xD
The DVD analogy is great to visualize the block universe. We know that the future events on the DVD already exist, even though we are at the beginning of the movie. It is just that the DVD player is working in a liner fashion. Our brains are similar, creating a liner forward flow of time. It's all very strange.
@@karmasutra4774 the question is what we define as a simulation. there is this one theory that states that our reality is a 3 dimensional projection (like a hologram) from a 2 dimensional external source. in a way time could be the result of the increase in dimensions. the true question after all is why? and what does it mean for our lifes and deaths? is dying like a wake up in another dimension/reality? or is it truly the end because we are just simulated for whatever reason.

This question is somewhat similar and reminds me of "If a tree falls in a forest and no one's around to hear it, does it make a sound?". Of course, the answer is subjective (depends on the logistics of how you look at it) however, the theory of the question is comparable. Lol. Ultimately, they are both a question of whether objects could continue to exist without being perceived.
Not really- these effects occur over huge distances- locally everyone pretty much experiences the same thing. Otherwise, the world would be pure chaos. The effects of things like time dilation on someone say walking or riding in a car relative to someone standing still on the sidewalk are so minuscule as to be nearly impossible to even measure- and that's even with super sensitive equipment developed specifically for that purpose. Humans could never perceive the difference nor would it affect their perspective in any significant way. The reason humans all have a different perspective on the same event is more down to psychology and the way we sense the world around us. We feel like we're totally objective and just see whatever is there but- the reality is that our field of vision is limited and we can't constantly scan around and actually look at every detail of everything going on around us- so instead, our eyes see what they can and our minds fill in the blanks to complete the picture. This is where the differences in what ppl see and experience start coming in- each person's mind fills in the blanks a little differently.
I find this topic on time interesting. As I sit here listening to the tape, I have come to realize that my perspective on time differs from other people's because we don't share the same events. So what is past present and future for me is altogether different then everyone else's. It's true that in a general sense we share certain similarities in our walk in life, but the outcome differs from person to person. Still, one thing is true, all our experiences as event's has a energy signature to it that can effect other future events. This is what makes up our reality.
@@q09876543 and technically speaking it’s physically impossible to occupy the same space time as someone else. Making all perspectives different at all times. That’s what I took from this as someone not overly educated on the topic. Really interesting stuff.
@@darthdewit6814 Your right in that when it comes to physics, I'm not the smartest duck in the pond, but I do know how to swim. so when it comes to time, I see it through the eyes of the sun. What I mean is, light needs to travel 8 minutes to get to the earth. So in the perspective of light, it's in the sun's now. But once it leaves the sun heading into space, the sun becomes lights past and space is in it's now. 8 minutes from then, the particle of light will enter the earth's atmosphere leaving space behind. Now space becomes the past and earth is in it's now. a few moments later, the photon hits a plant, giving the plant energy to become food, thus ending it's journey. All this was laid out even before the photon left the sun, for everything is in motion. The interesting thing to all of this is, the only thing that changes for the photon is it's position in space. But time wise, everything is in it's now.
Welcome to the aftermath, of whatever was really happening, when the story of the tower of babel was written. I firmly believe it went far far further than the languages being confounded. Whatever the reason was everybody suddenly began noticing perspective. Maybe inflection and motivation and simple co-operation suddenly became confused. Drove even family apart. Languages happened later. Scary thing is it is happening today and people argue all the time over nuance and semantics. Until we as a species find a way to get along, we're just gonna be samples in somebody's fossil collection, that proves that for all our grandstanding, we couldn't figure out, what cyanobacteria knew all along.
Dan Banks Of course they are. Look at them - they managed to create entire Universe out of nothing and didn't even stopped there. After they created our Universe they created an infinite multiverse from the same nothing again. They use something like absolutely abstract math and create something "physical", like space and time out of it. Then they turn around and take something real, like matter and compress it into infinitely dense and infinitely small nothing again. Just as you said it - wizards. Or maybe just charlatans.
What's really fascinating is when physics brings up new versions of old questions. Adherents of various religions have long debated whether God has already determined your fate and whether your actions are an inevitable part of God's plan OR if you have power of your own actions to change the world around you and control your own path. This video tackles almost exactly that question, just expressed in a different vocabulary and informed by advancements in what we have learned about the nature of the universe through the scientific method.
@@tonicrvnts I don't think philosophy and science are necessarily mutually exclusive; you can have a new scientific discovery that prompts new philosophical questions. Scientific discovery and philosophy oftentimes don't cancel each other out, but rather complement each other. The objectivity of science isn't undermined by intermingling with philosophy, in my opinion.
Just popped in from 2062; how did you watch in 2027? We learned in school about the Neurophyiscal Calamity that happened just around then; did the internet still work?

"Time is what stops everything from happening at once." Helps to decrease side effects caused by temporal displacement. But then, so will a glass of wine
tuna, I agree! Time may be the string which holds the 'time beads' gives them order and sequence which might be determined by your or another's consciousness. If now exists differently in different part of the Universe then 'now' is relative. I think part of the problem is our conditioning, it creates a mindset that needs 'planck time' to follow a particular sequence. Here's a playlist from my channel, I hope you & all might find it interesting it's called TIME ua-cam.com/play/PLEC8E0371526EC9AE.html
When you look at a distant star, you are not seeing the past. You are seeing their "present" but later. When you look at someone three meters away you are not seeing them in the present, you are seeing their "now" ten nanoseconds later in your present (Present = here and now) even though you share the same now (now = rate that time progresses _aka: reference frame_ )
Aren't you seeing their past in the present? I think you can't see their present in the present because light is so slow Future is "just" the present that hasn't been experienced yet.
As to your second point... you are still in different reference frames, but the difference is so small that it doesn't manifest in any meaningful way you can discern.
The present/now slice as defined in common use isn't the rate of time progression, it's the slice of time you currently inhabit, independent of rate. What your recent past light cone converges at You can have different rates and exist in the same now, like the earth and us moving at different rates because of different mass/gravity well
@@TheBigLou13 Try this: My past and yours exists as a series if seconds going back at least to our birth. *This is the definition of "Past"* What we see when we look at (say) the sun it is always 499 seconds from our present. We do not really see the suns "past" we see a single moment; the suns present 499 seconds later. That is not what we know as "Past" we cannot see the suns "past" 498 seconds later or its past "500" seconds later we can only see what is "present" for the sun (its here and now) 499 seconds later.
Here's a problem I continue to have with this stuff: Isn't this just about observation and not existence? Subjective perspectives don't define that which exists, just what is observable from those positions. Observable or not, things exist and things happen, but depending on where you're located, the data that tells you about it reaches you at different times compared to someone else's position. It's like calculating the observation capability is getting confused with idea of defining the actual existence of things and events. What am I missing?
Well for example, you have the subjective experience that you exist in the here and now. To you, that is your “actual existence”. So let’s say at time 0 you are in bed and that is your present and your subjective experience of you actually existing on your bed. However, depending on the velocities and direction an observer can see you at time 1 where you’re now out of bed, essentially into your future, at the very same moment you are still at time 0. So your subjective experience aside, objectively your future (to the observer) and your presence/past (your pov) exist in the same moment in reality. The question will then be, what is the definition for “actual existence”? To the observer your future self is “actually there and existing”. But to you, your future self does not “exist” yet.
@@whizzer2944 It has to do with the way spacetime interacts with mass. As you begin to travel faster, you also gain energy. E=mc2 (energy mass equivalence) you become more massive too. When you approach relativistic speeds, time within your inertial frame of reference slows down relative to everything outside of it. If you could actually reach the speed of light, time would stop dead. You would have effectively created a black hole. This is one of the reasons that nothing can travel faster than the speed of light. It would also take near infinite energy to accelerate something with mass to the speed of light.
So ,to me, you're saying you're viewing from a god angle, only you view it as a mount Olympus or Hindu god existence. Neptune holding Nep is as powerful as Jupiter. Yet Jupiter is the power. Are you Jupiter or Neptune the all powerful I know that's cartoons, but to me it seems the basic problem
Isn’t it very significant that you see into the past(like observing a distant star), but not into the future? EDIT: I personally think time is an illusion. All there is constant change. There is only now, and everything else is either predictions or memories. When you see the past of the distant star it’s just because of the inherent “lag” of the speed of light.
I thought the same, surely accelerating wouldn't skew the horizon to the point you see the future? He did say I think 200 year difference, which would still be 13b in the past, but wouldn't its present still be its present? Even though we will never see it bc of the distance?
@@reeeeeeee2143 ive tried learning the Lorentz transformations, i haven't learned enough of the language yet (math lol) but even if 2 observers see the same event happen at different times, that's still just varying degrees of the past, nobody could ever observe a future event, some word play could be used around black holes i suppose, but you still never see the future even near the event horizon, just a slower progressing present? Or something 😅
@@jessstuart7495 true, however if we could communicate instantaneously I firmly believe we would agree that the future has yet to occur, and that we can only observe each others pasts, to varying degrees depending on our acceleration
@@reeeeeeee2143 I saw your post on another comment where you said that even with time correction the observers would disagree on the time it occured. This is what I'm talking about! My problem is if we are different distances from an event, then it makes sense that one of us will see it first. And if we corrected by using the difference in our distances to the event we should agree on the moment in the past that it happened, even if its further in the past for one observer. All this still works with a real present, unless we disagree even after correcting for distances Edit also i don't see how your example shows any observers future? Supposing you agree that for example seeing something 13b ly away as it was 12b years ago is not the same as seeing the future?

The possibility that every possible timeline exists and we as humans can partially influence which timeline we experience is growing by the day and a mindfuck that I'm not sure most are ready for.
The past still exists. Physically. The future is the past. So is the present. And the present past as we conventionally see it, or tend to express it. Determinism because of special circumstances. Uh, big things happening.

It is possible for the "outside observer" to lay out the universe as countless of causal chains of infinite length, like ideals of a ring. As a person, the only reason why there is past and future is because our memory is arguably very much if not solely dependent on material, and due to entropy only the information of our perceived past is "recorded", regardless of free will or quantum uncertainty
But do we know upon what substrate memory is imprinted upon? Is it matter or energy? Matter is ultimately energy slowed down. So where do memories exist? And how would you observe this? And would the observation affect the observed?
@@kensurrency2564 If energy is slowed down sufficiently for memory to be imprinted upon, there is no problem. So, the dualism you throw up as a challenge, you yourself collapse in the next sentence. As to "where do memories exist?" No problem for Therence Denis' personal observer. "Here, off course" The main problem for the personal observer is, that the models at the base of our communication, always assume an "outside observer" for the determination of truth. Or, as Nietzsche said: "I am afraid we are not rid of God, as we still have faith in grammar"
I often walk down the road and imagine how something I do now will affect a person I will walk past in the distance. As in, can my current self causally effect the future of a stranger. And that's why I don't have any clothes on officer
the present is spaghettification. The "remembered" or relevant past is the event horizon, I would think. The future (the one all respective locales share, or unshare?) is, yes, an anachroncal black hole.
Might the "now" moment be how decoherence is expressed in the time dimension of space-time? So, in space we experience solid matter (as opposed to the wave it emerged from) and in time we experience the "now". The implication would be that time is emergent from mass, not fundamental. Also, the arrow of time would therefore be the result of our continuously expanding universe, which in turn "stretches" all matter, which in turn generates a continuous flow of new "now" moments. Another implication of this way of thinking is that entropy is the result of our expanding universe.
It's kinda like water flowing from a faucet. If that water represents reality, we could think of the point where it actually comes out of the faucet as "now." All the water inside the pipe and the faucet is the past. All the water flowing freely in the open is the future. But it doesn't matter where the water comes out of the faucet (now), because the entirety of the water exists, not just at that point, but on both sides, continuously flowing, and it's all a part of the same connected "reality" (the water).
So ontological mathematics is the study of the mathematical waveforms of mind that make up all of existence and your very being. The spacetime world isn't a material reality at all. It's the Holos, which is a mathematical Fourier projection from a frequency singularity known as the Source.
I question if it's possible for the concept of eternity to be defined and explained in a way that we can truly understand, not just know the technical definition. I think something like this is understood through a state of being, an awareness, a connection where you feel a part of it all and so the understanding is innate.
reality can not be understood through a concept because its thought and thought is created by memory which is a recording of the past but reality is always now. you see you can only understand something intellectually in terms of causation which is observation of the past so that put's you in a bind. that's why in eastern culture meditation was a key for understanding reality. if you want to understand the eternity get outside sit in a silent corner without thoughts and you will understand it.
Eternity by definition is bar far longer than we imagine. Even knowing by visual information what a million years are we still have no clue how to perceive it. A million dollars is easy to imagine. A million years, impossible to imagine. Time is not a physical construct. Hard to even imagine what an hour is. The clock and the calendar constantly needs adjustment.
This is the only UA-cam channel to regularly cause me to have an existential crisis. This, Boltzmann brains, and the quantum immortality episode have actually shook my world view
Who says we only travel forward in time? Think about you right now. You exist, you have memories of the past, and you don't know what will happen in the future. You travel forward in time one minute. You have new memories of what happened in that minute, and the future is still unclear. Now say you travel back in time two minutes. You don't have memories of what happened in those two minutes, because they haven't happened yet. The future is still unclear to your present self. We could be travelling back and forth, fast and slow, any which way around the fourth dimension, but we are completely unaware of this, as we are pretty much defined by our memories of the past.
My hypothesis is: There is no linear timeline that reality has to adhere to as time does not exist in conjunction with it. Rather the closest thing to a time "line" is one that each and every living being has (let's just go with humans to make it easy), as opposed to each and every one of us existing on the same time line. To make it simple, right now as I'm typing this comment up, it is happening in my own personal time. But for you, the viewer, you read it 20 years ago and for you, your current "present" is actually 20 years in my "future" just as some old hermit who's living in a cave in some far off country in YOUR present, may be physically existing and doing/thinking whatever it is they're doing/thinking except that for him, he hasn't consciously existed for over 80,000 years. A simpler version is: To me, the Lincoln assassination happened almost 200 years ago but right now for Abraham Lincoln it's 15 April 1865 and he's just sitting down in his seat to watch the show. In other words, reality exists, but we as _INDIVIDUALS_ are only experiencing it at our own pace and unless there are at least two people consciously existing at the exact same time, then despite there being almost 8,000,000,000 people on this planet, we all truly are alone. Again, just a hypothesis.
"Today, we're starting a deep dive into the nature of time." Yay... challenge accepted! Strap in, ladies and gents, 'cause this is gonna get good. EDIT: End of video - Brain hurty. But it hurts so good.
It seems we are so close to understanding what we don't now, our progress seems to be rapid and slow at the same time on all fronts, seems like we are merely energy surrounded by more energy in different states and we only use time to quantify our own existence, for all we know our 3 dimensional view could be clouding that our world universe could just be 1 photon when observed from higher dimensions, quantum particles seem to be in superpositon so imagine what we actually look like in higher dimensions observed by something that looks at us like we are as small as quarks 🤔💯
I never really get how being able to accurately map out the past and future as an observer is a necessity for a past and future to exist. Why cant there be a speed limit and a universal clock that nobody can find out? Like, if something happens a lightyear away, it intuitively seems to me that that event happens at that instant, even though I can only be affected by it a year later.
The past, present, and future are different depending on your perspective. How can there be a universal present if every single observer has a different present? From one observer's perspective, events that are in your future are in their past, and vice versa for some other observer. This implies that there is no one true past, present, or future.
To you it might seem like it happened a year ago, to someone in a different frame of reference, moving at a different constant speed compared to yours, that event happened 13 months ago. If this weren't true, then light would have moved faster than the speed of light in his frame of reference. If there's a speed limit, there can't be a universal clock and vice-versa. At least according to special relativity.
I feel the same way, it seems logical to me that when we look out into space we see the past, but never the future, and that a distant observer would have a present at the same instant as me, even though we arent causally connected in the present.
That's being nice. This is basically an advertisement for the himself. He tries so hard to seem deep, yet understandable. Do yourself a favor and just search for Brian Greene.
If we were to travel from Earth at the speed of light to the star that we recently observed to be exploding… what would it look like to us when we arrive to the destination? Would we see new planets being formed from the explosion, and would we see Earth as being billions of years older than when we left it, while we, ourselves, would still be the same age as we left?
No, if you travel 5 light-years away from earth at the speed of light: - you would have traveled for 5 years, i.e. you'd be 5 years older - you would find whatever space may look like 10 years after a supernova (bc it took 5 years for the light of the explosion to reach you + 5y for you to reach that space) - you would see the faraway earth exactly how you left it (as it takes 5y for the light of it to reach you, and that light started traveling through space right after you)
@@mymyscellany Look at this for a visual reference: hyperphysics.phy-astr.gsu.edu/hbase/Astro/unify.html My comment is saying that it was so early the 4 fundamental forces were still one force, aka the first second of the universe. Is that clearer now?
Okay, I can't say that I understood everything that was said in this video, however, I have a kind of cut-to-the-chase basic question: Since physicists believe that our sun will die out in billions of years, how can all possible realities exist simultaneously? Same thing for the viewpoint that our entire universe will one day cease to exist. Because wouldn't that mean that non-existence exists concurrently with existence?

Dyanmics is dependent on the evolution of energy. Time itself is a spatial dimension in 4D space-time. Technically it's traversable in any direction, although obviously it isn't since causality exists. We are forever propelled through the time spatial dimension, which may be dependent on the energy of the local volume. See the quantum theory of time by Joan Vaccaro for a proposed derivation of time itself through T-violation.
Time is a dimension. What if the universe from the beginning to the end happens in an instant. Just one moment, but for some reason we experience it one piece at a time

Observational reality is always infinitely far away from a "singular point" of infinitely high energy/information density (the relative past), and infinitely far away from a "singular point" of infinitely low energy/information density (the relative future). This is what establishes a frame of reference for relative observation. You can never reach either "point" through the passage of time relative to observation. No matter WHAT you do, each is infinitely far away.
I'm counting on my future self understanding this without the massive headache.

He is ultimately describing different perspectives within a universe. But ultimately all time flows the same. It just appears to move at different rates. Imagine a race where everyone starts at the same time and ends at the same time. To each racer it feels as if time is at normal speed and looking at everyobe else they going slow. But in reality they going the same speed just the time it takes light to travel from them to u you and have increased your distance from the origin of where they were.

Also, if a photon doesn't experience time because it travels at the speed of light, its "experience" is just one eternal moment that includes all of the past and future. The paradox of that is mind blowing, because we observe it as travelling through space, which implies time. This relative nature of "time" is one of countless things that prove that all of existence is eternal.
Your comment is better than the whole video explanation, towards materialism
And if we consider that all of us are moving on a expanding universe way faster than the speed of light, the same applies to us as well
@@Rkenichi That may be true. We seem to exist within spacetime from our perspective, but maybe in reality we're eternal and infinite.
Ive thought this many many times and commented it, maybe time doesn't exist at all and its consciousness that creates the illusion of it, everything you are in terms of energy, existed long before you and will continue to exist long after you're gone, but only if you think of time as linear, if no energy can be created or destroyed then everything is just here and always has been, without a mind to perceive anything what does it even mean? and if we are made of the same stuff that exists everywhere and we're conscious then the very system we came from has the components of consciousness therefore must also be conscious to some degree right?
@@mickyr171 Time is simply the illusory perception of the movement of "form" (I use quotations, because "form" is illusory as well). I think it's important to clarify the term "illusory". When we say it's an illusion, that doesn't mean it's not happening and isn't real. The illusion is real in the sense that it's a necessary part of experiencing anything. We just call it an illusion, because it's ephemeral and in a constant state of change/transformation. In a sense, it's a paradox.
Here's the interesting thing, in my opinion. I think consciousness is illusory as well, but it's the only thing that allows an experience of anything. Anything existing without consciousness is no experience at all, but consciousness is ephemeral and transforms as much as forms do. Basically, nothing in existence is static. Therefore, all of existence and experience is an illusion, but the illusion (constant transformation) is a necessary part of existence.
Everything is basically nothing, one thing, eternal, and infinite, and it experiences itself as a constant transformation of embodied forms and consciousness.

This question is somewhat similar and reminds me of "If a tree falls in a forest and no one's around to hear it, does it make a sound?". Of course, the answer is subjective (depends on the logistics of how you look at it) however, the theory of the question is comparable. Lol.
Ultimately, they are both a question of whether objects could continue to exist without being perceived.
This feels like an explanation of everyone’s perspective being different at all times.
Not really- these effects occur over huge distances- locally everyone pretty much experiences the same thing. Otherwise, the world would be pure chaos. The effects of things like time dilation on someone say walking or riding in a car relative to someone standing still on the sidewalk are so minuscule as to be nearly impossible to even measure- and that's even with super sensitive equipment developed specifically for that purpose. Humans could never perceive the difference nor would it affect their perspective in any significant way.
The reason humans all have a different perspective on the same event is more down to psychology and the way we sense the world around us. We feel like we're totally objective and just see whatever is there but- the reality is that our field of vision is limited and we can't constantly scan around and actually look at every detail of everything going on around us- so instead, our eyes see what they can and our minds fill in the blanks to complete the picture. This is where the differences in what ppl see and experience start coming in- each person's mind fills in the blanks a little differently.
I find this topic on time interesting. As I sit here listening to the tape, I have come to realize that my perspective on time differs from other people's because we don't share the same events. So what is past present and future for me is altogether different then everyone else's.
It's true that in a general sense we share certain similarities in our walk in life, but the outcome differs from person to person. Still, one thing is true, all our experiences as event's has a energy signature to it that can effect other future events. This is what makes up our reality.

@@darthdewit6814 Your right in that when it comes to physics, I'm not the smartest duck in the pond, but I do know how to swim.
so when it comes to time, I see it through the eyes of the sun. What I mean is, light needs to travel 8 minutes to get to the earth. So in the perspective of light, it's in the sun's now. But once it leaves the sun heading into space, the sun becomes lights past and space is in it's now. 8 minutes from then, the particle of light will enter the earth's atmosphere leaving space behind. Now space becomes the past and earth is in it's now. a few moments later, the photon hits a plant, giving the plant energy to become food, thus ending it's journey. All this was laid out even before the photon left the sun, for everything is in motion. The interesting thing to all of this is, the only thing that changes for the photon is it's position in space. But time wise, everything is in it's now.
Welcome to the aftermath, of whatever was really happening, when the story of the tower of babel was written. I firmly believe it went far far further than the languages being confounded.

As a Philosophy student, I can confirm, Physicists are wizards.
Dan Banks Of course they are. Look at them - they managed to create entire Universe out of nothing and didn't even stopped there. After they created our Universe they created an infinite multiverse from the same nothing again. They use something like absolutely abstract math and create something "physical", like space and time out of it. Then they turn around and take something real, like matter and compress it into infinitely dense and infinitely small nothing again. Just as you said it - wizards. Or maybe just charlatans.

Stuff like this is why I have always had a love for physics.
Stuff like this is why I can't sleep at night.
I think this is philosophy and physics together
Here's a problem I continue to have with this stuff: Isn't this just about observation and not existence? Subjective perspectives don't define that which exists, just what is observable from those positions. Observable or not, things exist and things happen, but depending on where you're located, the data that tells you about it reaches you at different times compared to someone else's position. It's like calculating the observation capability is getting confused with idea of defining the actual existence of things and events. What am I missing?
Well for example, you have the subjective experience that you exist in the here and now. To you, that is your “actual existence”. So let’s say at time 0 you are in bed and that is your present and your subjective experience of you actually existing on your bed. However, depending on the velocities and direction an observer can see you at time 1 where you’re now out of bed, essentially into your future, at the very same moment you are still at time 0. So your subjective experience aside, objectively your future (to the observer) and your presence/past (your pov) exist in the same moment in reality.
The question will then be, what is the definition for “actual existence”? To the observer your future self is “actually there and existing”. But to you, your future self does not “exist” yet.
Could the speed of light have something to do with this?
@@therealstephenschott. In a way yes apparently the faster you go the slower time passes go figure.
@@whizzer2944 It has to do with the way spacetime interacts with mass. As you begin to travel faster, you also gain energy. E=mc2 (energy mass equivalence) you become more massive too. When you approach relativistic speeds, time within your inertial frame of reference slows down relative to everything outside of it. If you could actually reach the speed of light, time would stop dead. You would have effectively created a black hole. This is one of the reasons that nothing can travel faster than the speed of light. It would also take near infinite energy to accelerate something with mass to the speed of light.

EDIT: I personally think time is an illusion. All there is constant change. There is only now, and everything else is either predictions or memories. When you see the past of the distant star it’s just because of the inherent “lag” of the speed of light.
I thought the same, surely accelerating wouldn't skew the horizon to the point you see the future? He did say I think 200 year difference, which would still be 13b in the past, but wouldn't its present still be its present? Even though we will never see it bc of the distance?
@@reeeeeeee2143 ive tried learning the Lorentz transformations, i haven't learned enough of the language yet (math lol) but even if 2 observers see the same event happen at different times, that's still just varying degrees of the past, nobody could ever observe a future event, some word play could be used around black holes i suppose, but you still never see the future even near the event horizon, just a slower progressing present? Or something 😅
Distant locations don't share the same clock. Before you interact with (directly or indirectly) a distant event, it isn't part of your reality.
@@jessstuart7495 true, however if we could communicate instantaneously I firmly believe we would agree that the future has yet to occur, and that we can only observe each others pasts, to varying degrees depending on our acceleration
@@reeeeeeee2143 I saw your post on another comment where you said that even with time correction the observers would disagree on the time it occured. This is what I'm talking about! My problem is if we are different distances from an event, then it makes sense that one of us will see it first. And if we corrected by using the difference in our distances to the event we should agree on the moment in the past that it happened, even if its further in the past for one observer. All this still works with a real present, unless we disagree even after correcting for distances
Edit also i don't see how your example shows any observers future? Supposing you agree that for example seeing something 13b ly away as it was 12b years ago is not the same as seeing the future?

It is possible for the "outside observer" to lay out the universe as countless of causal chains of infinite length, like ideals of a ring. As a person, the only reason why there is past and future is because our memory is arguably very much if not solely dependent on material, and due to entropy only the information of our perceived past is "recorded", regardless of free will or quantum uncertainty
But do we know upon what substrate memory is imprinted upon? Is it matter or energy? Matter is ultimately energy slowed down. So where do memories exist? And how would you observe this? And would the observation affect the observed?
@@kensurrency2564 If energy is slowed down sufficiently for memory to be imprinted upon, there is no problem. So, the dualism you throw up as a challenge, you yourself collapse in the next sentence.
As to "where do memories exist?" No problem for Therence Denis' personal observer. "Here, off course"
The main problem for the personal observer is, that the models at the base of our communication, always assume an "outside observer" for the determination of truth. Or, as Nietzsche said: "I am afraid we are not rid of God, as we still have faith in grammar"
I often walk down the road and imagine how something I do now will affect a person I will walk past in the distance. As in, can my current self causally effect the future of a stranger. And that's why I don't have any clothes on officer
Is the future a temporal black hole, and the present its event horizon?
One which we are progressing towards, one second at a time, yet doomed never to reach it?
the present is spaghettification. The "remembered" or relevant past is the event horizon, I would think. The future (the one all respective locales share, or unshare?) is, yes, an anachroncal black hole.
*short answer:*
Yes.
*long answer:*
Yeeeeeees.
Might the "now" moment be how decoherence is expressed in the time dimension of space-time? So, in space we experience solid matter (as opposed to the wave it emerged from) and in time we experience the "now". The implication would be that time is emergent from mass, not fundamental. Also, the arrow of time would therefore be the result of our continuously expanding universe, which in turn "stretches" all matter, which in turn generates a continuous flow of new "now" moments. Another implication of this way of thinking is that entropy is the result of our expanding universe.
Indubitably
It's kinda like water flowing from a faucet. If that water represents reality, we could think of the point where it actually comes out of the faucet as "now." All the water inside the pipe and the faucet is the past. All the water flowing freely in the open is the future. But it doesn't matter where the water comes out of the faucet (now), because the entirety of the water exists, not just at that point, but on both sides, continuously flowing, and it's all a part of the same connected "reality" (the water).
So ontological mathematics is the study of the mathematical waveforms of mind that make up all of existence and your very being. The spacetime world isn't a material reality at all. It's the Holos, which is a mathematical Fourier projection from a frequency singularity known as the Source.
I question if it's possible for the concept of eternity to be defined and explained in a way that we can truly understand, not just know the technical definition. I think something like this is understood through a state of being, an awareness, a connection where you feel a part of it all and so the understanding is innate.
reality can not be understood through a concept because its thought and thought is created by memory which is a recording of the past but reality is always now. you see you can only understand something intellectually in terms of causation which is observation of the past so that put's you in a bind. that's why in eastern culture meditation was a key for understanding reality. if you want to understand the eternity get outside sit in a silent corner without thoughts and you will understand it.
Eternity by definition is bar far longer than we imagine. Even knowing by visual information what a million years are we still have no clue how to perceive it. A million dollars is easy to imagine. A million years, impossible to imagine. Time is not a physical construct. Hard to even imagine what an hour is. The clock and the calendar constantly needs adjustment.

Who says we only travel forward in time? Think about you right now. You exist, you have memories of the past, and you don't know what will happen in the future. You travel forward in time one minute. You have new memories of what happened in that minute, and the future is still unclear. Now say you travel back in time two minutes. You don't have memories of what happened in those two minutes, because they haven't happened yet. The future is still unclear to your present self. We could be travelling back and forth, fast and slow, any which way around the fourth dimension, but we are completely unaware of this, as we are pretty much defined by our memories of the past.
This is the best explanation on this subject with visual representations making the ideas very clear.
My hypothesis is:
There is no linear timeline that reality has to adhere to as time does not exist in conjunction with it. Rather the closest thing to a time "line" is one that each and every living being has (let's just go with humans to make it easy), as opposed to each and every one of us existing on the same time line.
To make it simple, right now as I'm typing this comment up, it is happening in my own personal time. But for you, the viewer, you read it 20 years ago and for you, your current "present" is actually 20 years in my "future" just as some old hermit who's living in a cave in some far off country in YOUR present, may be physically existing and doing/thinking whatever it is they're doing/thinking except that for him, he hasn't consciously existed for over 80,000 years.
A simpler version is: To me, the Lincoln assassination happened almost 200 years ago but right now for Abraham Lincoln it's 15 April 1865 and he's just sitting down in his seat to watch the show.
In other words, reality exists, but we as _INDIVIDUALS_ are only experiencing it at our own pace and unless there are at least two people consciously existing at the exact same time, then despite there being almost 8,000,000,000 people on this planet, we all truly are alone.
Again, just a hypothesis.

It seems we are so close to understanding what we don't now, our progress seems to be rapid and slow at the same time on all fronts, seems like we are merely energy surrounded by more energy in different states and we only use time to quantify our own existence, for all we know our 3 dimensional view could be clouding that our world universe could just be 1 photon when observed from higher dimensions, quantum particles seem to be in superpositon so imagine what we actually look like in higher dimensions observed by something that looks at us like we are as small as quarks 🤔💯

That was one of the best yet. Integration of the observer prospect cannot be overlooked. Einstein speaks from the grave
Sometimes as I listen to these I wonder if I will cease to exist at any moment.
I never really get how being able to accurately map out the past and future as an observer is a necessity for a past and future to exist.
Why cant there be a speed limit and a universal clock that nobody can find out?
Like, if something happens a lightyear away, it intuitively seems to me that that event happens at that instant, even though I can only be affected by it a year later.
A universal clock? No. An infinite number of local clocks though? ...
Remember that time doesn't run at the same speed everywhere.
The past, present, and future are different depending on your perspective. How can there be a universal present if every single observer has a different present? From one observer's perspective, events that are in your future are in their past, and vice versa for some other observer. This implies that there is no one true past, present, or future.
To you it might seem like it happened a year ago, to someone in a different frame of reference, moving at a different constant speed compared to yours, that event happened 13 months ago. If this weren't true, then light would have moved faster than the speed of light in his frame of reference.
If there's a speed limit, there can't be a universal clock and vice-versa. At least according to special relativity.
I feel the same way, it seems logical to me that when we look out into space we see the past, but never the future, and that a distant observer would have a present at the same instant as me, even though we arent causally connected in the present.
This was a very metaphysical discussion, defined in very physical, scientific terms
That's being nice. This is basically an advertisement for the himself. He tries so hard to seem deep, yet understandable. Do yourself a favor and just search for Brian Greene.
If we were to travel from Earth at the speed of light to the star that we recently observed to be exploding… what would it look like to us when we arrive to the destination? Would we see new planets being formed from the explosion, and would we see Earth as being billions of years older than when we left it, while we, ourselves, would still be the same age as we left?
No, if you travel 5 light-years away from earth at the speed of light:
- you would have traveled for 5 years, i.e. you'd be 5 years older
- you would find whatever space may look like 10 years after a supernova (bc it took 5 years for the light of the explosion to reach you + 5y for you to reach that space)
- you would see the faraway earth exactly how you left it (as it takes 5y for the light of it to reach you, and that light started traveling through space right after you)

My weed isn't strong enough to handle this question bro.
I agree , that’s my intuition, there is the present moment, that’s it and that’s now.

What energy field? Your idea sounds relative but I don't see enough details about it.
Dyanmics is dependent on the evolution of energy. Time itself is a spatial dimension in 4D space-time. Technically it's traversable in any direction, although obviously it isn't since causality exists. We are forever propelled through the time spatial dimension, which may be dependent on the energy of the local volume. See the quantum theory of time by Joan Vaccaro for a proposed derivation of time itself through T-violation.

Observational reality is always infinitely far away from a "singular point" of infinitely high energy/information density (the relative past), and infinitely far away from a "singular point" of infinitely low energy/information density (the relative future).
This is what establishes a frame of reference for relative observation. You can never reach either "point" through the passage of time relative to observation. No matter WHAT you do, each is infinitely far away.
