There is a theory which says if anyone ever figures out the universe it will instantly be replaced by something even more unfathomable. There is another theory that says this has already happened. - Douglas Adams, Hitchhikers Guide to the Universe
It’s also a popular theory that the supermassives were what is called a direct collapse black hole. Matter was so dense in the beginning that certain objects simply collapsed into black holes before even becoming stars.
No no No! That is a cover up theory. It is a galactic monster or being swallowing all mass! Or a civilization trying to fight against heat death!!! Don't let them fool you there allliiiieeeeennns now and the federal government is going after the rogue elements or black projects covering up as I speak!!!

Thanks Simon, for everything I didn't know, for everything i'm yet to learn. It's great to hear a presenter who is not over dramatic on these subjects. You do a great job.
I like the idea that some of the supermassive black holes were actually formed from "shrapnel" from the big bang. That when the singularity "exploded" it did not do so evenly and some chunks were left that were still dense enough to remain as mini-singularities.
my probably wrong theory on the 'great attractor' is it could possibly be a new class of SMBH, but galactic in scale. if it was as large as this, it would be harder for an accretion disc to form with enough density to give the usual radiation signatures we see on other black holes. maybe. i dont know

Fascinating presentation. My personal take is that the sphere is the most plausible shape of the universe, and that there is a massive proportion not detectable. The universe is likened to earth in that matter migrates like tectonic plates across the medium, even ending (or beginning) by colliding in unimaginable explosions on the other side of this universal sphere. I imagined the image of galaxies at the distant limits were like the sun setting or rising and an optical illusion produces a larger object. Could these galaxies be disappearing over the horizon of a spherical universe giving the same impression? At first it seems the universe is flat due to the incredible distances involved. Maybe we haven't even seen the half of creation.
Relativity actually works on all things bigger than subatomic particles. It makes more sense to say that quantum mechanics is the science of the very small and relativity is the science of everything else.
The fact the black holes can predate the big bang is mind blowing because that means the universe is so much older that we thought which makes me feel even smaller than before which is also beautiful.
I have always been a fan of the cyclic universe theory. Somehow, knowing that all the Universe would someday contract into a point and explode into a new Universe was comforting. Matter that was outside the big bang feels like confirmation.

My small brain is having trouble fitting this all in 😂 But immensely interesting and humbling to know there are big brains that can actually understand and research this stuff
I've always liked the idea that because everything in the universe is made from the same stuff then humans are the universe observing and trying to understand itself. 🤷🙂👍
That was a roller coaster. As I‘m watching quite a lot of physics and cosmology channels, there were quite a few things that I never heard of, e.g. that the Great Attractor is directly opposite our massive black hole and could be the center of the big crunch, if any. Very interesting. Would this be compatible with the cycling universe (CCC)?
It has absolutely nothing whatsoever to do with CCC, conformal cyclic cosmology, and CCC has absolutely nothing to do with the Big Crunch. The whole point of CCC is that it’s conformal, hence there is no crunch or compression phase, going from one universe/aeon to the next is just a conformal transform, no compactification or crunch necessary. That’s not to say it isn’t a wildly speculative, and wildly lacking in ANY kind of evidence for its existence. If just about anyone other than Penrose had come up with it, I’m pretty sure no one would ever have given it the time of day, it’d be shut down the first time someone read it. Regarding the Great Attractor, it isn’t directly opposite Sag A*, our smbh. It’s completely obscured from view by the main disc and bulge of the milky way, that’s all. Moreover, it too, has absolutely nothing whatsoever to do with anything at all regarding the big crunch. Simon has NO clue what he’s talking about! If the crunch was ever to occur, by definition, just as happens in a bh, everything gets compressed towards a single point, it isn’t possible that any matter of any definition could possibly, somehow, magically miss out on the compression which is affecting literally the ENTIRE UNIVERSE except for some random bits which just happen to hold off the force of the entire universe collapsing in on itself. Like, sure, that sound realistic, right? Like I said, Simon has no idea WTF he’s even talking about. It’s SO far from being even a fringe theory it’s laughable he even mentioned it. Anyway, the Great Attractor has been known about for around 40kph years, I think, and there’s nothing mysterious about it, nothing strange or any kind of unknown physics. A woman almost got a Nobel prize a few years ago for her research into the Great Attractor, and trust me, they do NOT award Nobel prizes for anything remotely up in the air or unproven. That’s exactly why people don’t receive their prizes until 20 or so years after their discovery/work/etc, to be (reasonably) sure that the physics is on solid ground.
Black holes are not infinitely dense, in fact the larger they get, the lower their average density. Counterintuitively, if it were possible to create a waterproof shell just outside the event horizon of a supermassive black hole, it would float in water.
@@darthvicious9447 I can't post any links here to the many explanations of this that are out there, so to point you in the right direction, just google "supermassive black holes would float" Anyway. Anything infinitely dense would have infinite gravity, and this would be infinite at any distance. If you think otherwise, you do not understand infinity. It is more accurate when dealing with real objects of this nature to say that using the standard model, or anything by Einstein, we do not have the mathematics to explain what happens beyond the event horizon of a black hole, because when we plug the numbers into the best equations we have, we get infinities. That is a completely different thing from the reality being an infinitely dense object.
Personally, I think the Fuzzball concept of Black Holes makes more sense. To me, at least. Instead of being a hole at all, it’s a place in spacetime like the holographic universe you explained, the outer area of the sphere is the only part that matters, there is no other side or inside. It’s densely packed quantum foam made of spacetime effectively having its information (e.g; it’s energy) siphoned off back into our universe, which we can see in Hawking Radiation. That’s a massive simplification, but maybe it’s another side project video?
Sometimes i really need this break from Casual Criminalist to hear some theory of the universe to clense the pallet from all the murder and awfulness.... that I will surely go back to soon....
Too bad that the original movie was burnt and lost. Deemed too intense at test viewing when they showed more of hell. Seriously need to make a remake or sequel with all gloves off. Tie it into 40k too! A nod with a scientist named Geller who survives it and later researched a protective field to travel. Has the potential to be the scariest movie ever IMO. Something about hell being extra dimensional strikes terror into me.

Only a fool would get offended by it but here we are.
interesting theory! MBH's predating the current BigBang cycle, matter all draws together, maybe some black holes lag behind not all drawn in before another BB happens, they get more lifetimes and stars to eat and become massive black holes
As far as the great attractor goes we'll only have to wait 50 or so million years until we're on the other side of the galaxy and we'll get our 1st look. So, hopefully Simon will be ready to give us an update then
To me, the coolest thing about the universe is that it seems we know everything and absolutely nothing about it - at the same time. Take SMBHs possibly being older than the big bang due to a "cyclic" universe expanding and then contracting. As of now, no one can say for sure if that is even possible given theories like the big RIP. Dark energy overtook the force of gravity millions of years ago as the strongest spacial influence in the universe kinda eliminating the potential of the big CRUNCH due to expansion (ie, the universe is ~14.5B years old but its diameter is ~90B light years). Everything and nothing at the same time. Fascinating, Captain. Cheers....
May not even need a Big Crunch to start a new universe. Just a quantum fluctuation down the road a little bit (10^10^10^76 years, decades, seconds... doesn't matter with a number that huge). Could take into consideration the leftover particles from heat death and expansion. Maybe, I could be talking out of my behind.
Im fairly new to this kind of stuff, but if there are such things as both black and theoretical white holes, and they're supposed to work opposite of each other, could it be possible that a black hole could absorb more than its maximum, become a white hole, and end up expelling everything due to momentum, opposing magnetic forces, etc?
Short answer, no. Long answer, black holes eventually evaporate via hawking radiation, no matter how big they are. But this isn’t what a whit whole would be, a white hole would be a raging waterfall more or less. If you kept adding matter to a black hole it would increase its mass and thus is gravity would make it last longer.
Expanding on the previous reply, as far as we can tell, there isn't really a "maximum" amount of matter and/or energy that a black hole could take in. Everything that falls into a black hole simply becomes more black hole, its mass/energy adding to the black hole's mass. Just speculating, but I thinknif a black hole were to have a maximum intake, it would probably be equivalent to or just slightly less than it's own mass, yet even then you'd end up with a collision instead of "absorbtion," and the end result would be a doubly massive black hole.
I think that Super Massive Black Holes cause the big bang. When enough of them combine, bam and you have another big bang. What has not been sucked up in the super, super massive black hole just gets blown outside of the new universe.
If the center of black holes are a singularity where time stops and the big bang was also a singularity where time began...is there another Universe on the other side of black holes? Edit: nvm. You touched on this later in the video.
I've often thought about this. There is theoretical "stupendously large black holes" that exceed a trillion solar masses. Perhaps, once they get that big they go bang once again, whether it be in our dimension or another. ¯\_(ツ)_/¯ If such a black hole was in another 'verse and it reached our 'verse what would that even look like?
The energy could come back into this universe but in a different space and time altogether, that could be the past or the future as the black hole defies/breaks space and time (ad we know it)
I've often pondered about this. Given that spacetime is so heavily warped, that other universe would essentially be at the end of our time. If you subscribe to the idea of the big crunch, that universe on the other side of the black hole essentially would contain all the matter of our entire universe. This fits in with the cyclical theories pretty neatly, although it would mean that black holes if ever traversable, would be one way tickets to a new universe paid for by the end of the universe you were leaving. I'd much rather have them be a way to travel between galaxies considering the are the center of them.
Maybe they are the key to creating energy. I don't buy that energy cannot be created or destroyed and only transformed. That all energy that ever existed is it. Seriously it is depressing if heat death is the end of the universe.
Super massive black holes were able to be created because early stars were so extremely big that black holes formed inside the star. This actually has an effect of drawing in more mass unlike supernovae which push mass away
Soo do you think white holes could possible be or appear to be stars that have regular novas I’m unsure what the name is now as it eludes me (recurrent novas maybe?) Maybe those novas are explosions of matter being ejected from a white hole that is either at the centre of the star or just is the star. I mean I don’t know what a white hole would look like but I would suppose it’s the opposite of a black hole so would potentially look like a star of some sort and when matter is ejected it would potentially appear like a star that has recurrent novas every however often.( our own sun/star apparently does this and has recurrent novas every how ever many millions of years). I don’t think it’s 100% proven but I think there was some evidence to suggest our sun does do this and was a theorised to potentially explain some of the extinction events and other events possibly caused by the sun having recurrent novas.
It wasn't until Susskind tried explaining the holographic theory using string theory that it piqued my interest. It took me a few years to get my head around it. Now combine that with the fact that it's most certainly incomplete and possibly wrong. You start to understand the daunting task of unification.
We'll never observe a white hole directly because it would repel the light you're trying to use. Also, if it was the big bang, a second white hole showing up in our universe would likely be a cataclysmic event, right?

My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." "V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time." •Our sun's time bubble: "Terran Time" we know and have measured. •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .007-.07% faster, maybe. Just for reference. •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference. •Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here. (Time flows fastest here so it's best to have your motor boat.) ;-P A minute is a minute in all. It's the rate/flow I'm talking about. The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time." Pass it on, please and thank you
What if galaxies are galactic-sized planetary nebula?i.e remnants of supermassive stars that exploded and turned into supermassive blackholes shortly after the big bang?
It's actually more useful to listen to these without watching. As much as i enjoy the images, the scales are impossibly incomprehensible, especially when trying to gauge with the eyes
Dear Simon, in your first sentence you said that a black hole has infinite density. According to PBS Space Time that's not necessarily true. The black in the center of the Milky Way has the density of liquid water for example.
Afaik, the first hypothesis presented is related to Conformal Cyclic Cosmology a hypothesis presented by Roger Penrose. According to Penrose you should he able to see evidence of the "previous universe" through the detection of Hawking points in the CMB. Those points would be afterglow left by the evaporation of said black holes. Nothing he says would indicate the survival of a black hole through the aeon. In fact it would be impossible according to his hypothesis because for CCC to work there must be 0 mass left in the entire universe in order for the rescaling to occur
Every single black hole animation on the Internet always shows the accretion disk spinning way, way, WAY too slowly around the event horizon. This is matter spinning at insane speeds, being ripped apart by insane tidal forces, generating X-ray radiation just as it's about to fall inward.
It’s just so crazy to me that Earth, and all humans will cease to exist at some point in time. Wiping out all the progress we’ve achieved as humans and leaving no trace of our existence.
Fuck my life. It is the universe being politically correct! Ugh can't hide from the libs. Wait no!! It is the Patriarchy controlling us! White males strike again!!!
1: the cyclical universe theory is actually called the Big Bounce theory 2: Black holes are nowhere near as mysterious as human females. 3: white holes would make more sense if scientists considered an antimatter universe inside the center of the big bang explosion. 4: Although I'm already familiar with all of these theories this was still a fun video to watch.
What if movement is an illusion? Particles are just a wave in the matter field and just appear and disappear as the wave passes. Every spot in the universe has the intrinsic quality to create matter if the surrounding area promotes it. Time dilation is just a change in how fast or slow this appearances and disappearances occur. It makes sense that if your moving fast it is harder to these changes occur. Also if you have a lot of mass that tries to keep bodies together it would be harder to makes those changes from spot to spot
Take french lace stocking (or any stretchy fabric. Pinch and pull. Where you pinch is a contraction as an analogy of a black hole. But if you are at that singularity, that pinching is your norm. So you experience the rest of the fabric as being pulled away, moving away from you from. Like dark enegy. So we can say that if we are in a black hole, dark energy is the pulling of the previous univers.
white holes exist in the center of a blackholer because angular momentum must be conserved. the white hole behaves through the lens of hawkins radiation. Its only because light cannot be confined to a single vector because the energy state of the universe is atleast currently too dense for quantum fluctuation to not exist.
If black holes are supposedly singularities, which means they would be only one dimensional, and also have infinite mass. So...how can they be "super massive" if they already have infinite mass (hence the reason why light can't escape them)? I remember one strange item from advanced math is that (supposedly) some "infinities" are larger than other "infinities". When I saw that, I said, "Say, what?!" 🤯 I might have to look that back up again just to see if there's been any further explanation on *that* subject. 🤔
I think it's not that they have infinite mass, but they have infinite density, as their volume is considered to be 0. Any mass divided by something approaching 0, would have its density tending to infinity.
Theory: gravity Fact: mass warps space time and the Earth is spherical because of thermodynamics If y’all really wanna know about black holes, dark matter, and dark energy talk to Erebus. He’s best reached on New Moons 🌑 😊😊😊
It's interesting to think about information at the Big Bang. All information today was there, since it can't be created or destroyed. To me, this strongly implies there was something before the Big Bang, and that existence is somehow infinite in time. Energy is one thing, but I can't fathom how all this specific information could've come from nothing.
It could not have information does not come from nothing information only comes from an intelligent source that's is an observable fact information in nature is billions of times more complex than even the smartest computers we have I'm not sure then why scientists are so quick to assume naturalism.

So, in this random chance moment that I feel I have been placed in, I would like to thank you personally for the many happy and literally cherished memories I have that would not have taken place without your influence.
Video's you've written have been viewed across the world, but in my little house on my short street, you are known by name and writing talent alone.
But we know your name, Kevin, and even though we will never meet, we will remember you.
@@Unalochy Thank you, that's extremely kind!
Nice job everyone. Very professional
My small brain is having trouble fitting this all in 😂 But immensely interesting and humbling to know there are big brains that can actually understand and research this stuff
I've always liked the idea that because everything in the universe is made from the same stuff then humans are the universe observing and trying to understand itself. 🤷🙂👍
That was a roller coaster. As I‘m watching quite a lot of physics and cosmology channels, there were quite a few things that I never heard of, e.g. that the Great Attractor is directly opposite our massive black hole and could be the center of the big crunch, if any. Very interesting. Would this be compatible with the cycling universe (CCC)?
It has absolutely nothing whatsoever to do with CCC, conformal cyclic cosmology, and CCC has absolutely nothing to do with the Big Crunch. The whole point of CCC is that it’s conformal, hence there is no crunch or compression phase, going from one universe/aeon to the next is just a conformal transform, no compactification or crunch necessary. That’s not to say it isn’t a wildly speculative, and wildly lacking in ANY kind of evidence for its existence. If just about anyone other than Penrose had come up with it, I’m pretty sure no one would ever have given it the time of day, it’d be shut down the first time someone read it.
Regarding the Great Attractor, it isn’t directly opposite Sag A*, our smbh. It’s completely obscured from view by the main disc and bulge of the milky way, that’s all. Moreover, it too, has absolutely nothing whatsoever to do with anything at all regarding the big crunch. Simon has NO clue what he’s talking about! If the crunch was ever to occur, by definition, just as happens in a bh, everything gets compressed towards a single point, it isn’t possible that any matter of any definition could possibly, somehow, magically miss out on the compression which is affecting literally the ENTIRE UNIVERSE except for some random bits which just happen to hold off the force of the entire universe collapsing in on itself. Like, sure, that sound realistic, right? Like I said, Simon has no idea WTF he’s even talking about. It’s SO far from being even a fringe theory it’s laughable he even mentioned it. Anyway, the Great Attractor has been known about for around 40kph years, I think, and there’s nothing mysterious about it, nothing strange or any kind of unknown physics. A woman almost got a Nobel prize a few years ago for her research into the Great Attractor, and trust me, they do NOT award Nobel prizes for anything remotely up in the air or unproven. That’s exactly why people don’t receive their prizes until 20 or so years after their discovery/work/etc, to be (reasonably) sure that the physics is on solid ground.
Every time you said Supermassive Black Hole, I couldn't help but think of the song my Muse
Black holes are not infinitely dense, in fact the larger they get, the lower their average density. Counterintuitively, if it were possible to create a waterproof shell just outside the event horizon of a supermassive black hole, it would float in water.
If true, can you present your calculations?
@@darthvicious9447 I can't post any links here to the many explanations of this that are out there, so to point you in the right direction, just google "supermassive black holes would float"
Anyway. Anything infinitely dense would have infinite gravity, and this would be infinite at any distance. If you think otherwise, you do not understand infinity. It is more accurate when dealing with real objects of this nature to say that using the standard model, or anything by Einstein, we do not have the mathematics to explain what happens beyond the event horizon of a black hole, because when we plug the numbers into the best equations we have, we get infinities.
That is a completely different thing from the reality being an infinitely dense object.
Personally, I think the Fuzzball concept of Black Holes makes more sense. To me, at least. Instead of being a hole at all, it’s a place in spacetime like the holographic universe you explained, the outer area of the sphere is the only part that matters, there is no other side or inside. It’s densely packed quantum foam made of spacetime effectively having its information (e.g; it’s energy) siphoned off back into our universe, which we can see in Hawking Radiation.
That’s a massive simplification, but maybe it’s another side project video?
What really blows my mind is that science communication is still using the term 'theory' when they actually mean 'hypothesis'.
This comment deserves infinitely more attention. Unfortunately, most people do not know any better.
"So what is it?"
Man I love Simon tube so many good channels this man must work 24/7
I guess I’ve been watching too many videos to be sure, but is this a re-upload or have I just seen all this in other videos?
These facts are almost as epic as Simon’s beard. That is a glorious mane.
What’s the deal Babish? You didn’t cook a single thing
And you suddenly have a British accent
!!Bravo!!
Sometimes i really need this break from Casual Criminalist to hear some theory of the universe to clense the pallet from all the murder and awfulness.... that I will surely go back to soon....
Glad I could help!
Amazing.
Thanks🌌🔭
Every time Simon says event horizon I feel an urgent need to watch Event Horizon. In every video he mentions it.
Too bad that the original movie was burnt and lost. Deemed too intense at test viewing when they showed more of hell.
Seriously need to make a remake or sequel with all gloves off. Tie it into 40k too! A nod with a scientist named Geller who survives it and later researched a protective field to travel.
Has the potential to be the scariest movie ever IMO. Something about hell being extra dimensional strikes terror into me.
@@dianapennepacker6854 Not in our lives. People became even more sensitive than back when it was released. It would be remade as pg-13 with its balls cut off.
@@MaD0MaT Hey you never know! Get that funded privately. It is a cult classic! Anderson is down for a sequel.
You're right though on how Hollywood is getting even more sensitive. People are more sensitive.
We gave those people too much power. They are much louder than us.
There will never ever be a movie like Tropic Thunder for instance. That movie was brilliant. Only a fool would get offended by it but here we are.
interesting theory! MBH's predating the current BigBang cycle, matter all draws together, maybe some black holes lag behind not all drawn in before another BB happens, they get more lifetimes and stars to eat and become massive black holes
As far as the great attractor goes we'll only have to wait 50 or so million years until we're on the other side of the galaxy and we'll get our 1st look. So, hopefully Simon will be ready to give us an update then
what if the primordial universe was not a Singularity
but billions of black holes in orbits around each other?
LOVE THA SHOW!!!
To me, the coolest thing about the universe is that it seems we know everything and absolutely nothing about it - at the same time. Take SMBHs possibly being older than the big bang due to a "cyclic" universe expanding and then contracting. As of now, no one can say for sure if that is even possible given theories like the big RIP. Dark energy overtook the force of gravity millions of years ago as the strongest spacial influence in the universe kinda eliminating the potential of the big CRUNCH due to expansion (ie, the universe is ~14.5B years old but its diameter is ~90B light years). Everything and nothing at the same time. Fascinating, Captain. Cheers....
May not even need a Big Crunch to start a new universe. Just a quantum fluctuation down the road a little bit (10^10^10^76 years, decades, seconds... doesn't matter with a number that huge). Could take into consideration the leftover particles from heat death and expansion. Maybe, I could be talking out of my behind.
This is good stuff. from a very avid consumer of the fact boi. this is good stuff.
Science! Pretty much everything we know for certain will be eventually disproven. 🤔 ☺
I think Yuki Nagato developed the holographic universe, except I guess she would call everything data instead of information. :P
This nerdy throwback reference made me chuckle a bit
Im fairly new to this kind of stuff, but if there are such things as both black and theoretical white holes, and they're supposed to work opposite of each other, could it be possible that a black hole could absorb more than its maximum, become a white hole, and end up expelling everything due to momentum, opposing magnetic forces, etc?
Short answer, no. Long answer, black holes eventually evaporate via hawking radiation, no matter how big they are. But this isn’t what a whit whole would be, a white hole would be a raging waterfall more or less. If you kept adding matter to a black hole it would increase its mass and thus is gravity would make it last longer.
@ericmiesieski3165 A "White Hole" is a miniature big bang ... some think they are gateways from other Universes.
white holes are racist
"A white hole, but what is it?"
(Said by a cat on a spaceship - if you know, you know) 🙂
Expanding on the previous reply, as far as we can tell, there isn't really a "maximum" amount of matter and/or energy that a black hole could take in. Everything that falls into a black hole simply becomes more black hole, its mass/energy adding to the black hole's mass.
Just speculating, but I thinknif a black hole were to have a maximum intake, it would probably be equivalent to or just slightly less than it's own mass, yet even then you'd end up with a collision instead of "absorbtion," and the end result would be a doubly massive black hole.
If the bit of information was written at the Planck length an not something as massive as a atom? The Verse has such an incredible resolution.
I think that Super Massive Black Holes cause the big bang. When enough of them combine, bam and you have another big bang. What has not been sucked up in the super, super massive black hole just gets blown outside of the new universe.
If the center of black holes are a singularity where time stops and the big bang was also a singularity where time began...is there another Universe on the other side of black holes?
Edit: nvm. You touched on this later in the video.
I've often thought about this. There is theoretical "stupendously large black holes" that exceed a trillion solar masses. Perhaps, once they get that big they go bang once again, whether it be in our dimension or another. ¯\_(ツ)_/¯
If such a black hole was in another 'verse and it reached our 'verse what would that even look like?
The energy could come back into this universe but in a different space and time altogether, that could be the past or the future as the black hole defies/breaks space and time (ad we know it)
That's funny, I always do that too.
I've often pondered about this. Given that spacetime is so heavily warped, that other universe would essentially be at the end of our time. If you subscribe to the idea of the big crunch, that universe on the other side of the black hole essentially would contain all the matter of our entire universe. This fits in with the cyclical theories pretty neatly, although it would mean that black holes if ever traversable, would be one way tickets to a new universe paid for by the end of the universe you were leaving. I'd much rather have them be a way to travel between galaxies considering the are the center of them.
Maybe they are the key to creating energy. I don't buy that energy cannot be created or destroyed and only transformed. That all energy that ever existed is it.
Seriously it is depressing if heat death is the end of the universe.
Super massive black holes were able to be created because early stars were so extremely big that black holes formed inside the star. This actually has an effect of drawing in more mass unlike supernovae which push mass away
Soo do you think white holes could possible be or appear to be stars that have regular novas I’m unsure what the name is now as it eludes me (recurrent novas maybe?) Maybe those novas are explosions of matter being ejected from a white hole that is either at the centre of the star or just is the star.
I mean I don’t know what a white hole would look like but I would suppose it’s the opposite of a black hole so would potentially look like a star of some sort and when matter is ejected it would potentially appear like a star that has recurrent novas every however often.( our own sun/star apparently does this and has recurrent novas every how ever many millions of years). I don’t think it’s 100% proven but I think there was some evidence to suggest our sun does do this and was a theorised to potentially explain some of the extinction events and other events possibly caused by the sun having recurrent novas.
It wasn't until Susskind tried explaining the holographic theory using string theory that it piqued my
interest. It took me a few years to get my head around it. Now combine that with the fact that it's
most certainly incomplete and possibly wrong. You start to understand the daunting task of unification.
I love the white hole! It explains so much.
I wish Simon could make five hour videos. Also does anyone know if he can speak Czech? That would be really neat if he could.
Casual Criminalist has a number of 2-3 hour videos. And I believe he's stated on Brain Blaze that his wife speaks Czech but he is very bad at it
We'll never observe a white hole directly because it would repel the light you're trying to use. Also, if it was the big bang, a second white hole showing up in our universe would likely be a cataclysmic event, right?
Nice
9:59 into the video
about different scales behaving differently while may seem " unsatisfactory " is still true . The quantum sub-atomic particles Builds the macro particles such as the periodic table of elements and Galactic cores , and planets and moons etc .
My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." "V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time."
•Our sun's time bubble: "Terran Time" we know and have measured.
•Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .007-.07% faster, maybe. Just for reference.
•Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference.
•Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here. (Time flows fastest here so it's best to have your motor boat.) ;-P
A minute is a minute in all. It's the rate/flow I'm talking about.
The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."
Pass it on, please and thank you
How does Simon not have a space themed channel yet...
I mean, we do have a science channel...
What if galaxies are galactic-sized planetary nebula?i.e remnants of supermassive stars that exploded and turned into supermassive blackholes shortly after the big bang?
It's actually more useful to listen to these without watching. As much as i enjoy the images, the scales are impossibly incomprehensible, especially when trying to gauge with the eyes
I’ve seen a few white holes in my life. Open to seeing a black hole
😂
Dear Simon, in your first sentence you said that a black hole has infinite density. According to PBS Space Time that's not necessarily true. The black in the center of the Milky Way has the density of liquid water for example.
Just a suggestion - put subs on these vdos coz it's hard to understand without them.
Afaik, the first hypothesis presented is related to Conformal Cyclic Cosmology a hypothesis presented by Roger Penrose. According to Penrose you should he able to see evidence of the "previous universe" through the detection of Hawking points in the CMB. Those points would be afterglow left by the evaporation of said black holes. Nothing he says would indicate the survival of a black hole through the aeon. In fact it would be impossible according to his hypothesis because for CCC to work there must be 0 mass left in the entire universe in order for the rescaling to occur
Every single black hole animation on the Internet always shows the accretion disk spinning way, way, WAY too slowly around the event horizon. This is matter spinning at insane speeds, being ripped apart by insane tidal forces, generating X-ray radiation just as it's about to fall inward.
It’s just so crazy to me that Earth, and all humans will cease to exist at some point in time. Wiping out all the progress we’ve achieved as humans and leaving no trace of our existence.
Simon: "It's a white hole"
My brain, immediately: "So what is it?"
I've never seen one before, no one has, but I'm guessing it's a white hole.
Fuck my life. It is the universe being politically correct! Ugh can't hide from the libs. Wait no!! It is the Patriarchy controlling us! White males strike again!!!
@@SpaceWhaIe So what is it?
1: the cyclical universe theory is actually called the Big Bounce theory
2: Black holes are nowhere near as mysterious as human females.
3: white holes would make more sense if scientists considered an antimatter universe inside the center of the big bang explosion.
4: Although I'm already familiar with all of these theories this was still a fun video to watch.
Earth wasn't made for us, we were made for Earth.
What if movement is an illusion? Particles are just a wave in the matter field and just appear and disappear as the wave passes. Every spot in the universe has the intrinsic quality to create matter if the surrounding area promotes it. Time dilation is just a change in how fast or slow this appearances and disappearances occur. It makes sense that if your moving fast it is harder to these changes occur. Also if you have a lot of mass that tries to keep bodies together it would be harder to makes those changes from spot to spot
Side projects is my favorite of simons channels
Heard the background music somewhere before? What is this from? Or like?
Thank you for breaking down holographic universe theory like that. That's beautiful shit.
The universe: the ultimate mega project
Take french lace stocking (or any stretchy fabric.
Pinch and pull.
Where you pinch is a contraction as an analogy of a black hole.
But if you are at that singularity, that pinching is your norm. So you experience the rest of the fabric as being pulled away, moving away from you from. Like dark enegy.
So we can say that if we are in a black hole, dark energy is the pulling of the previous univers.
white holes exist in the center of a blackholer because angular momentum must be conserved. the white hole behaves through the lens of hawkins radiation. Its only because light cannot be confined to a single vector because the energy state of the universe is atleast currently too dense for quantum fluctuation to not exist.
I have found yet another Simon Whistler channel, gotta collect them all
"How many drugs did you ingest before coming up with this theory?" 😂😂😂 Had me dying
If black holes are supposedly singularities, which means they would be only one dimensional, and also have infinite mass. So...how can they be "super massive" if they already have infinite mass (hence the reason why light can't escape them)? I remember one strange item from advanced math is that (supposedly) some "infinities" are larger than other "infinities". When I saw that, I said, "Say, what?!" 🤯 I might have to look that back up again just to see if there's been any further explanation on *that* subject. 🤔
I think it's not that they have infinite mass, but they have infinite density, as their volume is considered to be 0. Any mass divided by something approaching 0, would have its density tending to infinity.
Theory: gravity
Fact: mass warps space time and the Earth is spherical because of thermodynamics
If y’all really wanna know about black holes, dark matter, and dark energy talk to Erebus. He’s best reached on New Moons 🌑
😊😊😊
No mention of Hawking radiation? Plenty of recent research and discussion over implications for SMBHs and such
Everyone should think about this before and after a DMT experience.
It's interesting to think about information at the Big Bang. All information today was there, since it can't be created or destroyed. To me, this strongly implies there was something before the Big Bang, and that existence is somehow infinite in time.
Energy is one thing, but I can't fathom how all this specific information could've come from nothing.
It could not have information does not come from nothing information only comes from an intelligent source that's is an observable fact information in nature is billions of times more complex than even the smartest computers we have I'm not sure then why scientists are so quick to assume naturalism.
7:49 Hahaha Sam has serious competition :-D based editors you always have Simon hahaha
