[@Giavani-t4k]

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.

I would like to directly thank you for the immense fun your writing has brought. Your writing is so on point that I have had some friends rewatch videos they saw months earlier at a separate gathering get excited and help drive the interest, and they still don't get the stories correctly the second time because of your bravado and skill interweaving crazy real stories with similarly crazy fiction (with amazing nerd references) 🖤 As a viewer, I do what I can to appease the youtube algorithm gods, likes, comments, and even frequent shares.

[@bazzer124]

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....

[@fordid42]

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.

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

[@xodiaq]

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?

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)?

[@aaronperelmuter8433]

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.

[@Trizzer89]

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

[@herbalterrorist420]

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.

[@DaveChapel-j4z]

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.

[@Art-h3c]

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?

[@scottbishop7899]

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)

[@josephriley4356]

That's funny, I always do that too.

[@Psykout]

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.

[@dianapennepacker6854]

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.

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?

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.

[@jmarth523]

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

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?

[@Ski_3_p_o]

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.

[@semaj_5022]

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.

When I think of the universe I think of a videocast by Rice University professor Jim Tour in which he said the simple cell has a membrane that has 10 to the 78 billion possibilities yet only one combination will work. The carbohydrates on the outside of the membrane are more complex than the RNA and DNA combined. When a material needs to be transported from one part of the cell to another, it builds a monorail and sends the needed material to its destination and then dissolves. Each part of the cell must come together at the right time for the cell be alive. Why am I saying this? Simon, our universe is like a cell. It is impossible for me to think that we will not one day find out how to visit every part of the universe on a time scale that fits our lifetimes. Professor Tour also said that since scientists have been studying the cell since the early 1950s, no progress has been made because of its complexity.

we solved all the problems here in earth and now we are ready to turn our eyes to space. who cares about space. How awesome is that. Even big bang is a theory that never can proved

[@neohermitist]

I think you may want to look into "electric universe" and "plasma universe" models.

The universe: the ultimate mega project

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?

[@stanislavkostarnov2157]

first read "cosmic mind blenders" which I guess would be more a subject for "Into the Shadows" or "Decoding the Unknown"

I like to think the big bang was the most massive of super massive Black holes dying and releasing all the matter it condensed as a white hole into space.

[@TauGDS]

Simon: "It's a white hole" My brain, immediately: "So what is it?"

[@SpaceWhaIe]

I've never seen one before, no one has, but I'm guessing it's a white hole.

[@dianapennepacker6854]

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!!!

[@mrthwibble]

​@@SpaceWhaIe So what is it?

[@Abioticwinter]

It's funny how a theory is fact with scientists. Their egos can't let it go. They know everything and are always right.

2:30 The possibility of a Big Crunch was ruled out years ago, when we measured the mass-energy content of the universe and saw that there isn't enough mass-energy to overcome the expansion caused by Dark Energy.

[@FuSiionCraft]

1 - no. Just no. They might come from Quasi-stars. It's the most logical, accepted and calculated explanation. They would start with a shit ton of mass, a lot of matter nearby and other Quasi-stars. The perfect breeding ground for SMBH.

Galactus likes Black Holes ⚫️!!

[@ThatWriterKevin]

Galactus just wants to fuck Death

The world was created to be perfect for humans in the same way that water perfectly fits a puddle. It is an outcome of the physics. If the physics were different we'd be perfectly tuned to exist in that one. Can we get beyond this?

[@YourLordshipBalthazar]

"So what is it?"

[@adamcummings20]

I have found yet another Simon Whistler channel, gotta collect them all

[@Jan12700]

There is also a theory that white holes are blackholes, because black holes aren't stable and only there for some seconds. But because of there mass they slow time so much down that we will never see this.

[@ThePhysicalReaction]

For a theory to be scientific, it doesn’t need to be provable, it’s needs to be DISPROVABLE.

[@moriahm8888]

I need a Simon channel just about space. 👨‍🚀

[@suzyturquoiseblue-]

Earth wasn't made for us, we were made for Earth.

[@ronaldlebeck9577]

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. 🤔

[@SreedharVenugopal]

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.
