The universe's greatest mystery is how many channels Simon has now. I swear I find a new one every other week. Serious request: PLEASE do an episode on one of your channel on just how many channels you actually have and what they are called/about.
1:05 - Chapter 1 - Big Crunch 2:45 - Mid roll ads 4:05 - Back to the video 6:35 - Chapter 2 - Big Chill 9:10 - Chapter 3 - Big Rip 11:20 - Chapter 4 - Un predictability
No matter how long the Universe has before it ends, there still wouldn't be enough time to watch every single video on every one of Simon's channels!!! 🤣🤣
And most of these are based on Dark Matter and/or Dark Energy, which as Simon said several times, we don't really know that much about. If our understanding of Dark Energy turns out to be wrong, where does that leave all these outcomes and what else could it mean. You could, to quote, "go insane in the p-brain" thinking about this stuff [deep reference there]
The big bounce at least gives us an answer to how the big bang happened and what came before. If we accept the heat death, we're still left with trying to figure out where the heat originally came from.
@@QBCPerdition But also, that would suggest that the universe is infinitely recycling and that it has no origin, no creation since it’s always been there in one form or the other. My human brain has it hard to accept that the universe just simply ‘is’.
At the end of the Big Rip all you are left with are quarks. Quarks cannot be pulled apart, and when you do try to pull them apart, the energy of the force binding them converts into a brand new quark which means as Spacetime continues to stretch and grow you will eventually be left with a quark foam permeating the entire, now much much larger, universe. These quarks would be everywhere throughout the entire universe and would then look like a new big bang and would suddenly slow the expansion of space to the same pace it was at the beginning of our cycle and the process would being anew with each quark acting a seed crystal upon which an entirely new and ever expanding universe is formed.
@@Chris-hx3om yes, with the speed of expansion being periodic. So not a cyclical universe, but a periodic fractal universe with time being the basis of the calculation that is generating the fractal as a whole.
Ive been watching most of your videos twice since finding your page a few months ago. First I watch the videos fully awake and then at some point Ill stream it on my tv when I have a hard time sleeping. Your monotone nature is very soothing and the nature if these videos and their subject matter distract me from whatever is going on in my head at the moment.
I love these esoteric subjects that are basically fodder for stoned conversations. The time scale makes this entirely moot for my life and I still gotta learn about it. Also,I shall have Walter take under advisement this underwear, as he is seemingly never fully sheathed.
As a thought experiment, let's say the universe is but a single living cell in a huge living body that extends endlessly from our perspective beyond the boundary of our cell... It's true that living cells "die" but the overall living creature never ceases being alive and growing and new cells replace the ones that left... The whole thing, our entire universe (that which came out of the big bang) could be like the individual "human cells" and would probably have consciousness...
The interesting part of the big rip is that this is where the strong nuclear force plays a huge role. A fundamental property of quarks is color confinement, where quarks are never alone. If you try to pull quarks apart, you put so much energy into the gluon field that it generates new quark pairs to pair up with the two quarks you pulled apart. This has been observed. So as the universe rapidly expands in the far future, it will try to pull apart all quark pairs in the universe, causing new pairs of quarks to be generated, causing the universe to try to pull those part, and the chain reaction repeats until we essentially end up with a new big bang. It's essentially a big bang in reverse of the big crunch and begins a cyclic universe, just in the forward direction rather than backwards.
I've had this thought before, 12:40 . If Vacuum Decay and the Higgs Field changes, wherever that begins it would never leave its "bubble" of the Universe. It would travel outward at the speed of light, but space would also still be expanding due to the Vacuum Pressures. Right?
Amazing video! 2:10 This theory haunts my mind and truly changes my perspective of life. Science makes things a bit bleak, but it’s also strangely comforting ✨
I've always had this thought of the universe also stopping at some point. Like a sort of "Explosion Theory", where if you look at an explosion, after X amount of time, everything settles in place. Debree might slowly fall from the sky and such, and perhaps we're still in the explosion or debree phase. Give or take another 14bil years, maybe everything just stops moving away, and just, is :D
"That's a 1 with 32,000 zeros after it." Why haven't we just invented a symbol that indicates "Don't even bother. You can't comprehend it." yet? I mean, me personally, I'd have just given up after the first thousand zeros, been like "A crazy long time from now in a universe we wouldn't even recognize as our own." And called it a day.
5:58 The big bounce hypothesis falls flat when you consider the photons that get away with nothing to slow them. Otherwise, it is just a static state with extra steps.
Photons don't have mass but they are a quanta of energy, since mass and energy are equivalent they too are affected by gravity so won't escape the big bounce.
@@joelharper7812 After traveling at the speed of light away from other matter for these amounts of time, do you imagine the light will make it back in time for the explosion? Just slowing light with gravity sounds hard enough, but to reverse its direction doesn't even sound possible.
@@joshuakarr-BibleMan As the density of the collapsing universe increases time would slow down from the perspective of the incoming photons yet to reach the singularity. Also if some photons were to escape the crunch then each cycle of the universe would begin with less mass than its previous iteration placing a hard limit to the number of possible cycles.
@@joelharper7812 Agreed. This decrease in the total available matter and energy proves the universe had to have started somewhere, somehow. It would be interesting to see scientists try to come up with an explanation for that some time.

I would hope it would be reborn again somehow after a trillion years or so or else this seems like a somewhat depressing thing to contemplate even if it is far off in the future.
According to my theory (Yes, I know, I know, LOL!), there's no mystery. The accelerating expansion means that more and more energy is being added to the universe, so it is heating up and will one day be so hot that it goes back to the state from whence it came. The spatial expansion means that spatial density is getting thinner, which in turn means that it is letting more and more energy in from the high-energy state "beneath" the fabric of spacetime (zero-point energy, or whatever you want to call it). Eventually, the spatial density is so thin it'll simply collapse, and the universe will be flooded with gamma radiation and undergo a reverse explosion, imploding in a Big Splat of crushing high-energy plasma. The high-energy state before, beneath and after the universe is the ground state of existence, while the cold, spatial, slow-time state of empty space as we know it is the unstable anomaly. And I'm not even kidding. Eventually the cosmos will be reabsorbed by what I call the protean (ever-changing) continuum, which is a roiling ocean of fluctuating high-energy plasma (from which the universe was created when a portion of it reached a certain low-energy threshold; a quark pool).
Yeah. First thing to absolutely remember is “You don’t know what you don’t know.” That sort of limits all thinking on a subject that is so far away since that time remaining allows for all manner of new information to come to light that can confirm one idea or another or most likely prove a new option that we don’t even have the capabilities to imagine at this time with our limited thinking. So I’m a cook right? Well the priests and church “Just knew” without a shadow of a doubt that the earth as God’s creation that housed humans was the centre of everything with everything revolving around us both literally and figuratively. They could not have been more wrong. A scientist proved that and was a Christian. So being the nice priests they were they jailed the scientist to shut him the fuck up. Well priests being shit at most things even at bein* jailers allowed a copy of his work to be released and then it was printed and the scientist got to see a copy before he died, in jail. The priests thought what they knew was 100% correct. But they didn’t know what they didn’t know. So now when you think that you’re so smart and know everything, just remember that today isn’t that day that we have decided that we know everything. Also you aren’t the smartest person in the world because watching this video makes you just plain old average, like almost everyone else in the world. That’s what average is. Also we don’t know what dark energy is and have a somewhat vague idea of what it does because it does what we say it does. What’s dark matter? Is it black? Nope nope nope. All ‘dark’ matter is is a type of baryonic matter THAT WE CANT DETECT with our current tech. We know both are there because if they weren’t then Lambda CDM universe model won’t work. And we KNOW that is THE defining model of the universe. So when it fails we add ‘stuff’ dark matter and energy in to make the model fit what we see. Are we refining the model based on observations? Or are we forcing the universe to fit the model? Oh and there are other models out there by the way that will work. The next in the pile is MOND it changes gravity to fit what we see. So now we are freely admitting that we don’t even know how what we see happening fits our mathematical models so we know that they have to be changed or another model selected. So how can we predict many many billions of years into the future when we know for absolute sure our model that we use for those predictions is broken and we freely admit that. Also the main reason by today’s understanding is that gravity will play the lead role in the demise on the universe. Pulls hard and we crunch, if it’s soft we fly out forever expanding till all energy is so spread out we just freeze at absolute zero. So gravity we know about that it’s easy… right? Nope not at all. There was no apple and Newton with Newtonian gravity works to a point. That point is basically trying to describe the planetary orbit of mercury. Oops new gravity needed. So thanks Einstein for Relitivity. That Realitivity gravity works brilliant. Oops not so much. Newtonian gravity works and only works on the small, while Einstein’s relativity only works on the big. There is a problem since gravity the attraction of baryonic matter to baryonic matter. Baryonic matter is what we can see and touch but does not make up all the matter we know of or stuff we know of. Light photons aren’t baryonic. A key indicator is “How many can I fit in that space?” Get 4 golf balls in a box that’s just big enough for them. Now try and fit in another 16 of them. They don’t fit because the box is just big enough for 4 balls. Get a torch and shine it on a spot and the beam makes a circle mostly. Now get 16 more torches and shine them on the same spot. Do they fit or do they just pile up higher and high the more you add? Baryonic vs non baryonic. But gravity affects photons as well. And they travel and have traveled 12 billion light years to us ONLY BECAUSE of gravitational lensing and that since light photons have no mass so they can go the speed of light should not be affected by gravity (Newtonian gravity) but the light photon beams are affected because we can see it happening and we tested it many times during eclipses of out sun. But Einstein’s Realativity gravity with curved space time and not mass works brilliantly. So is gravity a mass mass thing or a curved space time thing? It’s both right now because nothing would work otherwise. So we have a duck that’s both a horse and also Jupiter depending on what we need it to be. Truthfully I’d say we don’t actually really know what a duck is yet. So until we know definitively what a duck is, all our postulating on mostly gravity influenced problems are just that postulations, educated guesses. That is EXACTLY WHY scientists call things ‘theories’ instead of laws because they recognise they may need improvements or to be thrown out when greater understanding and knowledge is attained. You say ‘the law of gravity’ well it doesn’t work and we know it so we/humanity/scientists jumped the gun there by quite a bit even though it works correctly with everything they knew at the time. Oops.
Need you to do a video on the alternatives of the universe starting too :) Another great episode, and thanks for the eye catching boxers. I need to see them modelled one of these days. The wife likes baldies ;)
how can something expand in a fraction of a second to a diameter of ten light years ? Wouldn't that mean the the speed of light isn't the fastest thing ?
It's true that the speed of light is the limit for mass/energy within the universe. However, the expansion of space-time itself is not under this constraint.
"Universe man, Universe man Size of the entire universe man. Usually kind to smaller man. Universe man. He's got a watch with a minute hand, Millennium hand and an eon hand. When they meet it's a happy land. Powerful man, universe man." ~ lyrics from Particle Man by They Might Be Giants
So with limited astronomy knowledge maybe someone can explain this to me. If the big bang did indeed occur, then explain how two galaxies billions of light years from the singularity could be on a collision course.
Don't think of the universe as having exploded from a single point. Think of it is the surface of a balloon, which is being blown up (ignore the fact that the surface of the balloon is curved). NB. Think of the universe as the flat, 2D, *surface* of the balloon. Not the 3D balloon itself. Now, think of galaxies as ants on the surface. As the balloon expands, the ants all get moved away from each other. However, the ants, just like galaxies, don't need to be stationary. Its possible for nearby ants (galaxies) to be moving towards each other and collide.
Gravity... There's the for e if pushing out vs the force of pulling in. These two galaxies are close enough that the gravity is greater than the outward propulsion. Imagine you and your friend are on skate boards , both holding the same rope. The skateboards are on opposite sides of a slight ramp. The skateboard wants to go down the ramp but the rope is holding you both in place. That's pretty much a static version of the universe. Now imagine you are simply holding the rope but instead of a rope it's an elastic. You and your friend will start drifting apart from each other as the elastic pulls out, although you are moving slower than if there was no rope at all. Finally imagine the elastic is tough and will not snap but you and your friend are both pulling on it trying to get to each other. Even though your wheels are both trying to go down hill and the rope is trying to pull apart, the both of you keep getting closer. The same could be said about our relationship with other galaxies moving away from us. They just happen to be on bigger slopes that are steep enough that you can't overcome the slide and pull. As you get farther away the elastic is thinner and has less holding power.
Well black holes might be a theoretical plank star rather than a singularity. Basically the entire mass of the object has been squished into the plank length of space which is extremely small (1.616255(18)×10−35 m) creating an object so dense that not even light can escape it's pull. Makes more sense than the place holder singularity which is as you said "We don't know, and it doesn't fit our models". There is also a plank mass (2.176434(24)×10−8 kg) which to my understanding is a limit to how much mass can exist in a single plank length and frankly I'm not smart enough to answer as to whether or not that invalidates or confirms the idea of a plank star being what a black hole actually is. Just thought it was a neat hypothesis as supposed to the basically magical idea of a singularity.
I think that maybe what we think is expansion could actually be more of a current instead. Like if the universe "is shaped" like a dohnut then maybe the current of the universe is moving like the smoke in a smoke ring. It might look like every thing is moving further away but it's actually just particles (or matter in general on a universal scale) moving from the outer edge of the universe to the inner edge in a cycle. Kind of like this (⬇️⬆️)(⬆️⬇️) (Imagine the parentheses as the outer and inner edges of the universe if you sliced it in half and the arrows as the flow within it)
2:09 also as much as the Big Bang explains a lot it also has a lot of things it can’t explain and a few stars have been found that goes 100% against the Big Bang
Probably all of the above since we can only see part of it. For example, if the universe were torus-shaped with an infinitely small hole at the center then as we moved along the surface away from it everything would appear to spread out until heat death followed by a big rip. Once the space containing everything crossed the equator and started moving back toward the center everything would collapse back into the singularity at the center of the torus. If it kept pushing then everything would explode out of the other side as a white hole starting the process again.
I've gotta say, the sheath underwear are absolutely freaking AWESOME!!!!! Ever since discovering sheath underwear, I literally can't wear anything else and now have at least 30+.... and no, this is NOT a sponsored comment, just a VERY happy customer!!!
The bjg bounce isn't all that implausible....at least from a philosophical view. Almost everything in the universe is circular in nature. Stars planets galaxies etc. So why by that argument wouldn't life and the universe it inhabits also be circular in nature?
The universe will live and die just as we do albeit on a longer time span. Everything has a beginning and in end, its those moments in the middle that matter.
It sounds like Dark Energy started in an unstably high state, and almost immediately collapsed to its currently stable state. Possibly still at a false-zero state.
I don't like the big rip because it assumes that dark energy is so individually powerful it could overcome the gravity of a solid object. I disagree. In my opinion Dark Energy appears everywhere (or has the chance to) but as that new space appears the gravity overcomes it and pushes it out. Eventually into the vast areas of space where there isn't enough gravitational influence to push it further. That is why, eventually, there will instead be pockets of galaxies separated from others, so in the distant future there will be the milky way or Andromilky (a much cooler name imo) and maybe some other galaxies in our local cluster, beyond that, darkness. From there the model would then follow the Heat Death.
2 black holes at the end of time and one swallows the other but cannot contain the mass and collapses in on itself before exploding into a new "big bang"
The cmb can actually be picked up by any telescope. That was the problem, when they made the first telescope they kept hearing a noise. They thought it was bird shit and kept cleaning the the telescope hoping it to go away. (I'm quite sure I learned this in one of Simon's videos) they then found out its simply always there and have to make the telescopes ignore it.
Just radio telescopes. It was the first radio telescope built where that problem occurred. That's how they eventually figured out that the cmb existed.
Every thing has a birth and a death. Black Holes are born from an exploding star and grow using gravity to attract more mass into its center. Think of a BH as a roomba collecting dirt from an infinite floor, eventually it must be emptied. Galaxies combine with other galaxies until the spin (speed of light)of the singularity can no longer hold its mass together to ultimately explode (Big Bang). For man to think of just one Big Bang reminds me of the time when the Earth was the center of everything. They say the universe is expanding and all galaxies are moving away from each other. Many Galaxies cross paths from all directions, nothing is still in an infinite universe of entropy and neg-entropy.

This type of stuff is so interesting to me but also very sad.

When one tries to comprehend times of these magnitudes, it becomes totally useless exercise.
The key implication to consider though is that, at some point, time itself will come to an end. Whatever that may entail.

Eventually the cosmos will be reabsorbed by what I call the protean (ever-changing) continuum, which is a roiling ocean of fluctuating high-energy plasma (from which the universe was created when a portion of it reached a certain low-energy threshold; a quark pool).
Yeah. First thing to absolutely remember is “You don’t know what you don’t know.” That sort of limits all thinking on a subject that is so far away since that time remaining allows for all manner of new information to come to light that can confirm one idea or another or most likely prove a new option that we don’t even have the capabilities to imagine at this time with our limited thinking.
So I’m a cook right? Well the priests and church “Just knew” without a shadow of a doubt that the earth as God’s creation that housed humans was the centre of everything with everything revolving around us both literally and figuratively. They could not have been more wrong. A scientist proved that and was a Christian. So being the nice priests they were they jailed the scientist to shut him the fuck up. Well priests being shit at most things even at bein* jailers allowed a copy of his work to be released and then it was printed and the scientist got to see a copy before he died, in jail.
The priests thought what they knew was 100% correct. But they didn’t know what they didn’t know. So now when you think that you’re so smart and know everything, just remember that today isn’t that day that we have decided that we know everything. Also you aren’t the smartest person in the world because watching this video makes you just plain old average, like almost everyone else in the world. That’s what average is.
Also we don’t know what dark energy is and have a somewhat vague idea of what it does because it does what we say it does. What’s dark matter? Is it black? Nope nope nope. All ‘dark’ matter is is a type of baryonic matter THAT WE CANT DETECT with our current tech. We know both are there because if they weren’t then Lambda CDM universe model won’t work. And we KNOW that is THE defining model of the universe. So when it fails we add ‘stuff’ dark matter and energy in to make the model fit what we see. Are we refining the model based on observations? Or are we forcing the universe to fit the model? Oh and there are other models out there by the way that will work. The next in the pile is MOND it changes gravity to fit what we see.
So now we are freely admitting that we don’t even know how what we see happening fits our mathematical models so we know that they have to be changed or another model selected. So how can we predict many many billions of years into the future when we know for absolute sure our model that we use for those predictions is broken and we freely admit that.
Also the main reason by today’s understanding is that gravity will play the lead role in the demise on the universe. Pulls hard and we crunch, if it’s soft we fly out forever expanding till all energy is so spread out we just freeze at absolute zero.
So gravity we know about that it’s easy… right? Nope not at all. There was no apple and Newton with Newtonian gravity works to a point. That point is basically trying to describe the planetary orbit of mercury. Oops new gravity needed. So thanks Einstein for Relitivity. That Realitivity gravity works brilliant. Oops not so much. Newtonian gravity works and only works on the small, while Einstein’s relativity only works on the big.
There is a problem since gravity the attraction of baryonic matter to baryonic matter. Baryonic matter is what we can see and touch but does not make up all the matter we know of or stuff we know of. Light photons aren’t baryonic. A key indicator is “How many can I fit in that space?” Get 4 golf balls in a box that’s just big enough for them. Now try and fit in another 16 of them. They don’t fit because the box is just big enough for 4 balls. Get a torch and shine it on a spot and the beam makes a circle mostly. Now get 16 more torches and shine them on the same spot. Do they fit or do they just pile up higher and high the more you add? Baryonic vs non baryonic. But gravity affects photons as well. And they travel and have traveled 12 billion light years to us ONLY BECAUSE of gravitational lensing and that since light photons have no mass so they can go the speed of light should not be affected by gravity (Newtonian gravity) but the light photon beams are affected because we can see it happening and we tested it many times during eclipses of out sun. But Einstein’s Realativity gravity with curved space time and not mass works brilliantly.
So is gravity a mass mass thing or a curved space time thing? It’s both right now because nothing would work otherwise. So we have a duck that’s both a horse and also Jupiter depending on what we need it to be. Truthfully I’d say we don’t actually really know what a duck is yet.
So until we know definitively what a duck is, all our postulating on mostly gravity influenced problems are just that postulations, educated guesses.
That is EXACTLY WHY scientists call things ‘theories’ instead of laws because they recognise they may need improvements or to be thrown out when greater understanding and knowledge is attained. You say ‘the law of gravity’ well it doesn’t work and we know it so we/humanity/scientists jumped the gun there by quite a bit even though it works correctly with everything they knew at the time. Oops.
I asked Multivac, "How many channels does Simon Whistler have?" It printed out the following answer, "INSUFFICIENT DATA FOR MEANINGFUL ANSWER."
So the edge would be coming back while the inner is headed outer… that would be fun to watch.
This dude is taking over RUclips with all these damn channels 🤣
Need you to do a video on the alternatives of the universe starting too :) Another great episode, and thanks for the eye catching boxers. I need to see them modelled one of these days. The wife likes baldies ;)
good one. proper gravitas.
how can something expand in a fraction of a second to a diameter of ten light years ? Wouldn't that mean the the speed of light isn't the fastest thing ?
It's true that the speed of light is the limit for mass/energy within the universe. However, the expansion of space-time itself is not under this constraint.
"Universe man, Universe man
Size of the entire universe man.
Usually kind to smaller man.
Universe man.
He's got a watch with a minute hand,
Millennium hand and an eon hand.
When they meet it's a happy land.
Powerful man, universe man."

Big Rip gets my vote, but Big Crunch would be epic to behold
So with limited astronomy knowledge maybe someone can explain this to me. If the big bang did indeed occur, then explain how two galaxies billions of light years from the singularity could be on a collision course.
Don't think of the universe as having exploded from a single point. Think of it is the surface of a balloon, which is being blown up (ignore the fact that the surface of the balloon is curved).
NB. Think of the universe as the flat, 2D, *surface* of the balloon. Not the 3D balloon itself.
Now, think of galaxies as ants on the surface. As the balloon expands, the ants all get moved away from each other. However, the ants, just like galaxies, don't need to be stationary. Its possible for nearby ants (galaxies) to be moving towards each other and collide.
Gravity... There's the for e if pushing out vs the force of pulling in. These two galaxies are close enough that the gravity is greater than the outward propulsion.
Imagine you and your friend are on skate boards , both holding the same rope. The skateboards are on opposite sides of a slight ramp. The skateboard wants to go down the ramp but the rope is holding you both in place. That's pretty much a static version of the universe. Now imagine you are simply holding the rope but instead of a rope it's an elastic. You and your friend will start drifting apart from each other as the elastic pulls out, although you are moving slower than if there was no rope at all. Finally imagine the elastic is tough and will not snap but you and your friend are both pulling on it trying to get to each other. Even though your wheels are both trying to go down hill and the rope is trying to pull apart, the both of you keep getting closer.
The same could be said about our relationship with other galaxies moving away from us. They just happen to be on bigger slopes that are steep enough that you can't overcome the slide and pull. As you get farther away the elastic is thinner and has less holding power.
Singularity is effectively applied as a placeholder for 'we don't know'
Same goes for dark matter, a veritable placeholder for phenomena our models can't comprehend
It's the equivelant of "and then some magic happens" :-)
Well black holes might be a theoretical plank star rather than a singularity. Basically the entire mass of the object has been squished into the plank length of space which is extremely small (1.616255(18)×10−35 m) creating an object so dense that not even light can escape it's pull. Makes more sense than the place holder singularity which is as you said "We don't know, and it doesn't fit our models". There is also a plank mass (2.176434(24)×10−8 kg) which to my understanding is a limit to how much mass can exist in a single plank length and frankly I'm not smart enough to answer as to whether or not that invalidates or confirms the idea of a plank star being what a black hole actually is. Just thought it was a neat hypothesis as supposed to the basically magical idea of a singularity.
😅
I think that maybe what we think is expansion could actually be more of a current instead.
Like if the universe "is shaped" like a dohnut then maybe the current of the universe is moving like the smoke in a smoke ring.
It might look like every thing is moving further away but it's actually just particles (or matter in general on a universal scale) moving from the outer edge of the universe to the inner edge in a cycle.
Kind of like this (⬇️⬆️)(⬆️⬇️)
(Imagine the parentheses as the outer and inner edges of the universe if you sliced it in half and the arrows as the flow within it)
2:09 also as much as the Big Bang explains a lot it also has a lot of things it can’t explain and a few stars have been found that goes 100% against the Big Bang
Realy I like this video so so much
If this were a Casual-Criminalist-style channel, Simon would be crying about how little of this he understands.
Me at 8 years old when they said the sun is going to explode in 6 billion years: 😭
The Big Chill scenario doesn’t require that the amount of matter is finite and in fact we don’t know if it is or not.
I think I know the answer without watching. But I've done mushrooms and DMT a few times.....
Probably all of the above since we can only see part of it. For example, if the universe were torus-shaped with an infinitely small hole at the center then as we moved along the surface away from it everything would appear to spread out until heat death followed by a big rip. Once the space containing everything crossed the equator and started moving back toward the center everything would collapse back into the singularity at the center of the torus. If it kept pushing then everything would explode out of the other side as a white hole starting the process again.
Imagine trying to know the fate of something you can’t even hope to understand
When we don’t know what isdark energy and matter, I think for the end - who knows?
Good one.
Fascinating eggskull
At the moment i am more concerned with the heat-death of my graphics card😢
I've gotta say, the sheath underwear are absolutely freaking AWESOME!!!!!
Ever since discovering sheath underwear, I literally can't wear anything else and now have at least 30+.... and no, this is NOT a sponsored comment, just a VERY happy customer!!!
I've gotta say, I don't believe you don't work for sheath.
The bjg bounce isn't all that implausible....at least from a philosophical view. Almost everything in the universe is circular in nature. Stars planets galaxies etc.
So why by that argument wouldn't life and the universe it inhabits also be circular in nature?
The universe will live and die just as we do albeit on a longer time span. Everything has a beginning and in end, its those moments in the middle that matter.
Nice vid 🍀🎆
It sounds like Dark Energy started in an unstably high state, and almost immediately collapsed to its currently stable state. Possibly still at a false-zero state.
I don't like the big rip because it assumes that dark energy is so individually powerful it could overcome the gravity of a solid object. I disagree. In my opinion Dark Energy appears everywhere (or has the chance to) but as that new space appears the gravity overcomes it and pushes it out. Eventually into the vast areas of space where there isn't enough gravitational influence to push it further. That is why, eventually, there will instead be pockets of galaxies separated from others, so in the distant future there will be the milky way or Andromilky (a much cooler name imo) and maybe some other galaxies in our local cluster, beyond that, darkness.
From there the model would then follow the Heat Death.
That being said. Vacuum Decay is quite the scary option, since it could have already started and just not reached here. We wouldn't see it either.
Fate of the universe? It'll fizzle out.
2 black holes at the end of time and one swallows the other but cannot contain the mass and collapses in on itself before exploding into a new "big bang"
There was a debate early on if galaxies should be classified as separate universes. Obviously that idea wasn't very popular so now we have galaxies.
No one as ever complained about being dead. Truth is no human as been dead long enough to complain.
well Simon that was certainly heartwarming.lol.
The cmb can actually be picked up by any telescope. That was the problem, when they made the first telescope they kept hearing a noise. They thought it was bird shit and kept cleaning the the telescope hoping it to go away. (I'm quite sure I learned this in one of Simon's videos) they then found out its simply always there and have to make the telescopes ignore it.
Just radio telescopes. It was the first radio telescope built where that problem occurred. That's how they eventually figured out that the cmb existed.
When I was ten I worried about school bullies and my mums cooking. As an adult I worry about my children and the heat death of the universe.
Every thing has a birth and a death. Black Holes are born from an exploding star and grow using gravity to attract more mass into its center. Think of a BH as a roomba collecting dirt from an infinite floor, eventually it must be emptied. Galaxies combine with other galaxies until the spin (speed of light)of the singularity can no longer hold its mass together to ultimately explode (Big Bang). For man to think of just one Big Bang reminds me of the time when the Earth was the center of everything. They say the universe is expanding and all galaxies are moving away from each other. Many Galaxies cross paths from all directions, nothing is still in an infinite universe of entropy and neg-entropy.
Thank you .
What is the soundtrack at the Big Crunch section please?
