Instead of waisting your time on TikTok, Instagram and tweeting, Shouldn't we all get together and try to solve some of space mysteries? I'm amazed that so many people don't really care.They just want to live ,and than just cease to exist.
Isn’t that why the majority of us hopped in our universal black hole for? To try life on earth and spawn our conscious in a newly born human body? .. Ask yourself what’s more probable, hopping in to unravel secrets or to have a taste? So questioning why most of us are living and deluded in life is an already answered question.
People have different interests.
@@jorsehph9216 yea because the way the system is built if we was all equal then most would think of better things if were then we can all think about other things instead of money
That's because of religion.... religion has killed the curiosity of people .....ooh why is it like that because god made it so ....like grow up mate
Not everyone has what it takes to become a scientist
Was wondering where my socks were going!
All makes sense now. Cheers.
I have a black dog that takes all my socks
Mine are holy but I'm not religious
My camera bag is a literal black hole! 🤣🤣🤣
It's weird, but it would potentially describe the origine of time, speed of light and matter compressed into a planet sized singularity (and not the singularity derived from Einsteins theory) and the fact that no Alien seems to have knocked at our door. It would also implicate that the event horizon is the end of the universe as we almost see it, and that the event horizon at Sagittarius A is actually the surface of the "singularity" . Wow !
Is not lie, of you believe it
Wow! Things are getting spooky!
Aliens are here lol
@@jzj2212 you're saying singularities are alien-made ? Well, why not ? 🙂
@@rubbermoetroken no I’m saying that black holes create new universes. Also you aliens have not knocked at our door lol have you been watching David Grusch @congress about the ufos.
I can't thank you enough for unraveling the secrets of the universe through your videos. Your dedication to spreading knowledge is truly admirable.
There was secrets revealed in this video? No way really
@@geemanbmw Right. Opinions stated as facts.
Sounds AI generated.
I think it's mandatory now for people to use the term "Not even light can escape" when describing black holes. It is really annoying now.
That's because they do not know anything
Not even physicists can escape this cliche.
I like how he says far fetched, the whole universe is far fetched
Yeah, CLEARLY, extremely advanced *human* technology like the so called “UFOs” or “UAPs” and the German stolen blueprints of Haunebu ll and Haunebu l is not proof of faster than lightning travel capable aircrafts not mentioning the USA’s own aircraft which are faster than light unlike those N-Germany ones.
The space inside the black hole is always curved it contradicts that the Universe is flat.
Yes, we're in the Black Hole, and time is reversed. Instead of time flowing towards the singularity, we're flowing away from it. The acceleration of the expansion of space corresponds to us entering the ergosphere of the Black Hole from the opposite direction.
I’ve always thought inside a black hole is the creation of a big bang.
🤔
Makes sense!
this sounds more plausible
Everytime they say that nothing can escape I think to myself, "well right, that's obvious but can light escape? Surely even light could escape. No, unless explicitly told otherwise I'm going to choose to ASSUME that light can EASILY escape black holes." So, I'm glad they remind me every time.
ALWAYS thought that? You were born with that intrinsic knowledge?
I believe that the ideas of Cosmologists should start to be taken with a large pinch of cosmic salt.
Agreed
i spent 3 years at cosmetology school and trust me these so-called-cosmetologists don't know the first thing about doing hair.
@@ClintLock1 Ha ha.
If you squish an orange down all you'll get is orange juice and orange pulp flying all over the place unless there is some space underneath the orange for most of it to fall into.
What if a star is just 4 dimensional sphere? When it moves through our space we see it getting bigger and bigger and then we see its explosion at the moment when it escapes from our 3d reality. It leaves a fancy hole in it, that we see as a black hole, like sort of a volumetric 3d cut of our Universe.
The graphics in these videos are always so trippy.
Sorry, the same scientists are saying,”In astrophysics, spaghettification is the tidal effect caused by strong gravitational fields. When falling towards a black hole, for example, an object is stretched in the direction of the black hole (and compressed perpendicular to it as it falls).” you would not just cross the boundary.
That doesn't happen if the black hole is sufficiently massive or if you are small enough. Tidal forces are when the gravitation forces at one end of your body are substantially greater than the ones at the other end. The shorter the distance between those two points, or the larger the black hole, the less the difference in those forces.
force due to gravitation varies over the square of the distance between the centre of masses of 2 objects so a sufficiently large black hole with a big enough radius would not exhibit tidal forces on a human falling past the event horizon because the force acting on the feet of an infalling observer would not be significantly more than that acting on their head. Tidal forces would be experienced further past that boundary, so it would be possible to pass the horizon without knowing
My thought of where the universe came is finally made into a video 😊
Wow - didn’t even touch on all the coincidences that seemingly support the idea.
By the mass of the observable Universe the event horizon has grown to one tenth size of the distributed mass, so at some point the ratio converges and there is an event horizon beyond the three thin spherical bands. The falling black hole collides with the frog eggs full to where new mass creates insufficient new event horizon to admit more mass escape velocity at the rigid sphere is the speed of light. The Singularity has a constant relative size, being a thin spherical sheet, it expands at critical mass leaving the center empty. What goes on at the Singularity is that string is laid down like a ball of yarn and the particles are churned into arrangements of gold. The tiny has more time, so that at the Singularity time is balanced to infinite mass and one may experience time or no time until the object has merged and expanded. So that there is time for the expanding string to file through all the elements of the previous two Universe, leaving two shells of increasing pattern density each another volume to the Singularity. The edges of these two shells are Singularity and spread at a rate equal to the expanding sphere. How 1/3 critical mass is collected from each band is unknown.
Well said! Maybe add toads next time.... maybe 😂
Makes perfect sense to me.
It sounds pretty interesting. I would like to turn an orange into a tiny black hole!
I think there is a good reason that we may live in a brutal big black hole, i also think that the normal big bang stuff is real. But one thing i dont understand is, how can a big enough star turn into something that brutal that noone/nothing can escape it ? We literally know sadly WAY too less to understand what is going on.
Consider this:
1. The event horizon
A) Nothing, not even light, can escape the event horizon of a black hole, because the space(time) itself flows in faster
B) Nothing, not even light, can escape the horizon of our observable universe, because space(time) itself expands faster
2. The relativity of time
A) Think of the movie interstellar. It demonstrated that circling around a black hole, time is significantly slower. Seconds near Gargantua meant decades on earth
B) similarly, the billions of years since the big bang, up to now, until the death of our universe in an estimated 100 trillion years into the future of our time, could happen across the 10^67 years a black hole may exist. Compare it to the event of someone in a near-death experience seeing their entire life (several decades) flash before their eyes in mere milliseconds. While in this instance, it's just the brain perceiving time differently, rather than it being the result of a physical effect, the result is similar: Time dilation. Time on the "inside" and "outside" flow differently.
3. The singularity
A) Each black hole has at its center a single point, a singularity, where all information converges. Our laws of physics and understanding break down at this point.
B) Our universe started from a singularity, a single point of spacetime, that since expanded. Our laws of physics and understanding break down at this point.
For those who'd argue that a black hole must also have a corresponding white hole that ejects mass, my best guess is that our big bang is that white hole.
4. Dark Energy
A) In our universe, about 68 to 70 % of the total mass come from dark energy, a mystical and undetectable force that is responsible for the accelerated expansion of our universe. It acts opposite gravity, meaning it repels instead of attracting mass.
B)Tying it in with black holes, which are not only absorbing mass and energy, but spacetime itself, imagine a black hole outside our universe (like on a higher plane, a parent universe) is constantly pulling in spacetime. This spacetime enters our universe and gets added, stretching our universe in the process (accelerating its expansion). Since we can't detect spacetime itself, this is the magic and elusive "dark energy" that math predicts, but sensors will never find.
These are just my points, my guesses and opinions, ideas that to me make it look like our universe and a black hole are just 2 sides of the same coin. I'm not a physicist, nor am I literate in the math that matters, the theories that such hypotheses are built upon or any other relevant field. It's just the rambling of someone who keeps asking "how" and "why" throughout his life.
But just based on these "strange coincidences", I personally can't shake the feeling that the "our universe lies within a black hole" hypothesis must be true.
if we are at black hole then we have answer why we cant see first 300 000 years , because its not possible to see over event horizon*?
If our universe formed after being sucked into a black hole wouldn’t we just be on the other side if a black hole that has since dissipated?
That would be the other theory called a White Hole
It creates a new region of space time
This AI voice has to be the dude from some of the tomorrow’s world segments.
This is the Ancient Aliens of physics.
What’s outside space? More space. Yeah it makes total sense.
I said this once 10 years ago and people are STILL laughing AT my ass 😂😂😂
Theres a difference between approaching the speed of light, and appraoching a body where time stands still.
Part of the information problem has to recognise, that if you are going back in time to a destination of year zero, you are also entering a domain before the entities information even existed.
So how can you lose the information of an entity, that never existed in a relative sense ?
But that would imply the the evnt horizon is not just a holographic 3d to 2d representation, but also a 4d to 2d representation.
At leats if you accept that both space and time are the same fabric.
In which case, black holes become a history book of creation, rather than just a quantum particle hologram source.
It’s an astrophysical version of simulation theory … black holes all the way down.
i think its worth doing whatever we can to test this
I wonder how a black hole tells about its electrical charge when not even light (electromagnetic radiation) can escape?
What if we did live in a black hole and it explains why we move so fast throughout space.
I always wondered this actually. Like, if it was like an hourglass.
I couldn't help but wonder if the concepts of reincarnation and resurrection are in human consciousness because of originating on the basis of the universal laws.
The concept of Logos seems to be appropriate to what is being revealed.
The strange thing is we could be that small our hole universe could be inside a vacuum cleaner of some other deity like creature as we don't kno how big we are we only have our own measurements to go by so 1 billion of our miles could really be just a fraction of a millimetre in theres we could just be surviving on a speck of dust in a timeless vacuum
I see you've seen the ending of Men in Black as well.
If we’re a black hole, then times going backwards, which would explain why everything’s expanding because it’s a reversal of everything converging on the black hole
What's curios is if you ask a physicist where is the point of the big bang, they say it's everywhere at every point in space. And a black hole you cannot discern any one point it's all the singularity. We may actually be living in a universal sized black hole that ate so much matter that it's event horizon is infinite like the universe and the rate at which it grows is much faster than the speed of light.
What would even trip you out even further is time dilation on a grand scale. For all we know the big bang happened yesterday because the closer you are to the gravitational event time gives in over gravity. So time slows down to a halt to the person closer to the event while outside in stages gravity gives in over time. Time in essence speeds up the further away you are from the event. So while we may think the big bang happened billions of years ago the closer you get to the event you go backwards in time. One micro second at the big bang could be millions of years outside the bang.
So for example you create a Blackhole and your visually see it from outside the horizon you time its survival at one day. Everything inside the Blackhole experienced billions of years if not trillions from their observational point of view.
Similar to how they depict difference between earth and outer space maybe this black hole is unique to earth alone. Maybe someone created this black hole in the beginning God created the heavens and earth and the earth was without form and VOID.
worth pointing out that as the rate of time slows to nothing at the event horizon, it therefore takes infinity for an event horizon to form.. as the universe isn't infinite, or you cannot wait for infinity.. to an outside observer aka here on Earth, there can be no black holes... as it takes infinity for an event horizon to form.. but lets called them 99.99% pseudo blacks holes.
He says is right the average density of black hole depends on mass or Schwartz radius if Schwartz radius is big enough the black hole density will be equal to that of universe actually if universe is 10 times the size the size of observable universe
It does not matter. As we cannot influence it.
Yeah mon , we need a really good UA-cam influencer to show that hole a thing a two
Time=Gravity at each set distance "Gu" X (distance divided by the speed)"U" then multiple it exponentially by "G" + 1"U"???
lol
The term "black hole" is miss leading. It isn't a hole at all. Why do you think that as stars get smaller and more dense, they get dimmer? The insane amount of gravity doesn't allow as much light to escape. A black hole isn't a hole at all, it's still a star. If we could survive getting past the event horizon, they would discover that a star is still chugging away inside. It has become so condensed and its gravity has become so powerful that it can't be observed in traditional ways and appears as a hole.
I dont understand how we could, without being spaghettified as soon as we cross the EH.
Agreed. How would time dilation work too?? Where did the black hole come from?? There's no way anyone can prove anything. Similar to universal computer simulation theory, I think a scientist has let their god-complex get the better of them.
That doesn't happen if you are very small compared to the size of the black hole.
@@ebresheawell then you better watch out for them nickel sized blackholes 🕳

Black holes, the lungs of the multiverses.Breathe in breathe out.
Nope, it's more like suck it and suck it some more🥴😵💫
The satan pit is calling to us all.
When i think about thier theories it would make sense our universe is in a black hole. The say our observable universe seems to be expanding and contracting which fits the idea of a black hole with hawking radiation thus shrinking of the black hole and its growth from absorbing other objects. Also, light only goes so far in our universe. Think about escape velocity. I’d assume if you shine a light in space it will only go so far (think of our sun). It’s light can’t escape the black hole we sit in. As I’m typing I’m think about the supermassive black hole in the center of our galaxy. Maybe that’s slowly pulling us in and we are in the event horizon but then you’d have to ask what’s pushing us out? Fascinating
Kind of makes sense. The same way they tell us we have visited the moon but with all of our technology not one space shuttle has been successful in returning.
I've often said that, in order for ANY black hole to exist, then ETERNITY must have already passed.
out there in the cozmoss....
If the Earth rotates around a black hole then how do we live inside a black hole? That doesnt make much sense to me.
Stand between two large perfectly parallel mirrors and tell me how many images of yourself you can count.
in conclusion: we have no idea. But there seems to be at least one Brian Green and one Brian Cox and a reassuring theatrical narrator voice proclaiming all matter of repetitious fascinating glittering soundbites (probably as AI generated as the voice and the images) that basically add up to another singularity of zero substance. It's all black holes all the way down. I love the subject and it's all the more painful to see how it is diffused en masse with such disregard for knowledge.
so I subscribed
This is speculation for the sake of talk. The wildest form of speculation I have ever seen in science.
If we were inside a black hole surely the gravity all around would be nuts
Assuming that gravity does really exist
I have come up with this theory before with a friend about tens years ago so maybe it could be true. We don’t know.
Assuming that infinitely mass objects can create black holes and that our early universe was made up of an infinitely large hot gas cloud, then why didn’t the early universe collapse upon itself?
I’m getting mindfecked thinking about this.
Because the simulation says so
That's a nice question! But, look at our universe, there's only few points that you can see black holes... it must be something like that aswell
What I want to know is whats behind a black hole...we see images that I'm assuming are the front view
Sure there's no reason why we "can't" be inside a black hole, but I don't hear any evidence that we are. Basically it's just a "what if". What if we were inside a black hole? And of course that black hole has to be big enough and we were far enough from the singularity that it doesn't affect any measurements?
If we’re between the event horizon and the singularity than what we think of as general relativity is actually special relativity to anyone on the other side of the event horizon.
So what your saying is the event @ the singles bar they would think the general public is special on the other side? Is that what you're saying ? You lost me 🫨
Turns out, we're the Heechee!
Maybe since the universe is structurally flat and space bends based on the mass of objects in it like a ball on paper, maybe a black hole is just a rip or tear in space? A hole and things fall thru it. So it only makes sense there another side of the hole or rip 😅
That actually is a pretty common concept that scientist consider.
For example, a piece of paper to us is pretty damn flat. There’s obviously some 3D structure to it but if you zoom in with a microscope it will have an insane amount of structure.
So the universe could be like a piece of paper and we’re just so small that it seems so vast and dynamic.
What’s inside a black hole?
We know what.
Many compressed galaxies.
A solid mass of material that will burst back out and create another universe.
I've been reliably informed that we aren't, so relax.
Me I still have a hard time imagination "infinite Entropy" in its self that happens in there, it's like since everything just "is" all at once, all possibilities of future probable potential transformation of energy is always just there, there's no (other than hawking radiation) "lost" per say, its like it just "is" always changing Actual forms without transformation or what.??? Because isn't Entropy in a set space(volume) just minimal??? Because black hole it's like they have like near infinite in its space(volume)
Maybe Black holes are not objects anymore, what happened was when the star collapsed it broke space and time, it folded it like a wormhole, and it's like a spinning part of space time that just warps space time, perhaps until it's large enough to cause another big bang.
I think it's just condensed mass
@@user-cb4qd5fc1x Mass has to have a breaking point, because we shoot mass particles at each other in particle colliders. So at some energy point, mass breaks apart right? Leaving an energy void that is space itself or a space field of energy.
A Black hole maybe nothing more than a bubble of energy caught in a sort of time loop of space folded in on itself, sustained by that warping of space time.
so why can we observe balck holes if we would live in a balck hole? is it ok to be black holes in balck hole? shouldn’t it be eliminate the fact?
so its the event horizon, broadly, that cant be passed (by light etc etc, except under certain {maybe} circumstances)
much like how you can jump on earth, despite gravity, yet not reach escape velocity...by jumping at least
i may very well be wrong! thats just my simple analogy!
I think it's similar to when you take a shower and seeing all the water is being sucked into the pipe.
We are. It's different than what he's describing.
If we have been created by a big bang from another univers through black hole and everything is shredded to nothing and created over and over again. I’m glad I don’t have to live to see that happening any time soon.
There is no shredding. It's just a process of existence
The space inside the black hole is always curved it contradict that the Universe is flat.
This "theory" has been disproven as there are several missing parts to prove the theory. The evidence comes close to proving but it runs into problems with these missing items causing problems to properly prove the theory.
I have watched this stuff for years, never heard this narrator before.

Most of the video doesn't talk about the main topic/title.
We can use the immense pressures on the planet Venus or in the Mariana trench to get acclimated. 😂
I think the universe is a kind of black hole which has turned inside out the whole universe is falling into one single point which is any direction in this universe. I came up with the black hole family tree universe a few years ago now
lol their intro is casually stolen from the loki opening
We are spining with a bhole. Duh! Also creates a time prob. Faster time than outside the bhole?
Would need to be couple super bholes slamming together to create.
So, ok, based on the idea that we’re in a black hole in a parent universe, that means potentially there are universes in each black hole in this universe, which is, as they propose inside a black hole. So, following on from that, the black hole in the parent universe might also be inside another black hole. So, an entire existence based upon a Russian doll sort of situation where there's nothing but a succession of black holes infinitely up and down. Somehow, just doesn't seem plausible.
Life is fractal
and that's why humans have no concept of infinity, infinity plus infinity is still infinity. things make more sense when we don't sweat the minutia, that being said, there may be an aspect of nature that isn't quite evident to us, if we take everything at face value of course its not going to make sense.
Why not?
Look at black holes as simply lenses to whatever is on the other side. Most likely true reality. As we know time can be changed, it can be bent though motion through space. Hence spacetime, space and time are one thing.
As we approach a black hole, matter increases and so time changes. Time and space both get stretched equally, hence the apparent dilation of time. Subjectively. Time and space remain the same. As would be the case for any object entering a black hole. As the matter is stretched from our perspective, so also will the time and the space be stretched. Therefore from the perspective of anything passing into a black hole, they will have had a smooth ride. No spaghettification nonsense. That's just made up.
This is why the mass of a black hole MUST by default, be infinite
We are information. I don’t need a soul if I am information… beam me up.🖖
Kinda makes sense.
They're individual multiverses thus why their is other life forms in existence we will never be able to teach them nor them us because we can't leave ours nor they can live theirs.
How is it that the universe is expanding? Shouldn't it be contracting to a singularity?
if its within a blackhole as theorized here, as the blackhole (our observable universe is within) gains more matter from its surroundings it gains in size
@@brookbeck1944 thanks professor nowhere
If light cannot escape, how do we know it exists at all, as all astrology is in light years. Idk
Its neither a theory or hypothesis.

@@FiveThings2018 A handful of crackpots, the same crew that were talking about all existence being a hologram a few years back, they have no way to prove any of it and just keep coming up with fanciful ideas, probably with the help of weed.
Maybe we went through it . I think it's just how stars or universe's start growing like mass starters.
Physical space is a function of time. Without time matter is irrelevant. So most of what exists, exists without time. That means it didn't begin, and therefore, cannot end.
Ok, so what would we be observing now with those telescopes in deep space?
Might be, probably, possible, not sure, if, well they dont know squat, and get paid for knowing squat give us a break
No we wouldn’t be spaghettified in our 100 year life span as if we had just crossed the event horizon our 100 (relative) years would take millions of years to the rest of the universe outside of the event horizon.
I think tge spagetified term is fake cause how you can understand sometimes there are illusions in space,so i mean that we can see it being spagetified but it isnt in the reality
The black hole is between your ears
Getting rather annoyed by these pretentious-sounding AIs. Here's a tip, lower the overused language to sound less AI-generated. That being said, it's a good video. I wonder if the universe prior to ours had "crunched" and then turning into a black hole. Since the W Equation is not less than negative one, the universe will not expand extremely fast, leading to a rip, but might instead crunch. However, the heat death scenario remains a possibility. Cosmic cyclic cosmology is also a viable theory. Interestingly, in this model, both the end and the beginning of the universe have quantum fluctuations.
God created everything in a system. Understand the creator…then understand the creators work…
How?
Well, I'm 5 minutes in and there' sno Brian Cox OR Brian Greene....just some crap voiceover.
We not throw something in to see what happens we got the tech to get there why not at least try
Why 'some' scientists think.
Lol
Good lucky being smashed by pressure at the pure quark-string like core. Stay on open space guys.😂
If our universe is expanding at a faster rate than speed of light, this concept sounded like we’re in a black hole 😮
I doubt this. As Einstein's theory on relativity is that we understand everything up to the singularity. So we know what's occurring up until the singularity.
Not necessarily. If Einstein's theory was actually valid then it wouldn't have room for an error such as that
So... are we in or are we out? Make up your mind already.. 😤
No evidence that we are, it's just a thought experiment that makes massive assumptions about things we can't measure.
Both a once, it's a multiverse after all
There's a lot of rambling in this video.
