I believe Infinity only exists as a concept. If we are able to map something, it has to be finite, because that map has to lead somewhere. You cannot have an infinite map. Unless the 3 dimensions exist as Pi does, where there is no theoretical end because new space and matter is created as we observe it, like when we observe quantum particles. Science is scary when you fear the unknown. The more you study it, the less you know.

Have you seen that timelapse looking at the earth from space going through it's seasons? It looks like it's breathing! A heartbeat. Just wow. We are totally a reflection of the universe and its ways. I realize more now that I am deeply connected to the universe and how it works, as we all are! And this magnificent process, of entropic harmony. Oh my gosh... there it is. After life, there is death.. and then there is life again. There is levels to this madness!!! Wow!!!! Just got tingles alllllll over, my hair is literally standing up.. it was crazy coming to this realization and feeling that energy in that very moment! Tells me I may be on to something 🌠. I've believed for sometime now that we do get to advance to another plane depending on how well we do in this stage, but, your video really helped to put this into perspective for me. So thank you for helping me along my journey!!! 🖖

[@ossiedunstan4419]

It only expands, the only equal force on matter and its consequences in our universe is the velocity gained from the big bang, to make the claim the universe of matter is contracting and expanding you need to show evidence of this and the force responsible, all i got ws absurd assertions using ignorance and self entitled insanity in this video , Nothing in it is based on the reality we know at this time.

How about this...a finite Universe within infinite space? I am not saying that is the case, a realistic scenario, merely a thought experiment. I guess the proposal rests on the idea of a finite Universe embedded within an infinite spacetime. Which kind of ties in with Einstein's description of the Universe as being 'finite yet unbounded', in other words curved upon itself. Yet within that curvature there is no actual boundary...which is of course impossible to visualise for the human mind, but has a ring of truth...

[@meowcula]

The end of the universe is one of my favourite topics in astrophysics. There's so many interesting ideas to explore, even when the universe is utterly dark, forever chilling. Could you imagine our sun as a black dwarf? No light, no heat, much smaller than its former self. If the gravity wasn't so strong, you could walk on it. Then look up to an utterly black sky. Plenty of matter out there, but no light to see it by. Objects only aware of each other by the gravitational influence they all have on each other. Or much, much later, when all the matter in the universe has fully degenerated and it reaches that point of heat death. No energy, nothing moving, not even a subatomic wiggle. With nothing able to happen ever again, does time even have meaning at that point? What is time without causality? Does it even exist at that point? Some people find all this stuff dark, inhuman and horribly terrifying. I don't. I find it all fascinating and actually a great comfort that we are just an insignificant blip in the grand scheme of things. Suits me. By the time the events above happen (assuming that's how things will happen), humanity will have long since ceased to exist I'm very sure.

[@Just.A.T-Rex]

As long as something is headed towards entropy, time exists and passes relative to that something.

[@meowcula]

@@Just.A.T-Rex Indeed. But imagine a scenario where the universe is so stretched out that no two particles could interact any more... can entropy even increase from there? It's mind blowing to think about.

[@egonieser]

Humans are like cockroaches, we will find a way to persist. We might not be Homo Sapiens or might even be fully digital or even exist as pure energy, but we'll still be there in some form, you'll see. We're the only species that has managed to survive extinction level events that have wiped out 99% of other species with much, much more primitive lifestyle and no technology. Ultimately, it will get to the point where there really is nothing in the universe except maybe the very end of the universe itself that can really stop us in any way because we learn to control and manipulate matter, energy to more sophisticated and complex levels by the year now, and the speed of our advancement is accelerating. There might even come a point, as we exceed type 3 civilization status that we can control and manipulate dark matter and energy, and as such might even reverse or slow down the big freeze. In the end of the day, the universe is controlled by the microverse. The Quantum level of things dictates what happens in the universe. We're reaching the point of understanding and being able to manipulate the quantum realm to a primitive degree. Give it a few hundred years where we have mastered it - if we master the quantum realm, we master the entire universe because what is the universe? It's a load of quantum particles, fields, waves clumping together to form matter and energy.

[@666chapelofblood]

@@egonieser If we could travel between the stars and observe other planets, we'd probably find civilisations on those planets that have been destroyed by weapons, war or nature. Ones possibly as advanced or more advanced than ours. What makes you think we are exceptional?

Without observing redshift we wouldn't know about the expansion of the universe, and as far as I'm aware would not be able to discover it any other way. It's strange to think that far future civilizations would not even be able to guess that there were once galaxies outside of their own gravity bound bubble and, should they come across what past civilizations had discovered, may assume it was myth as opposed to science. Makes you wonder what we've already missed.

the thought of universes randomly crunching and banging in an infinite interval is both comforting and terrifying

[@MegaThurstonator]

But think about it this way, life would remain interesting if in each iteration of the universe crunching, history would be happening in a very different manner, the humans born in the past iteration would not be born in the next iteration, and our memories would be wiped clean of the past iteration so we would have no memory of the death of the last universe and all previous lives within it. I don't know if the big crunch will happen because the heat death is most widely accepted, but just because something is widely accepted does not mean that it is slated to happen. At the end of the day, all three theories of the universe's ultimate fate are only theories. At best, they give us an understanding of the results of scientific processes. At worst, they scare us to where we don't sleep at night. I'm not asking for you to hold out hope (or continue to) that the Big Crunch will happen, or that the Heat Death should be accepted because I see why some people and scientists don't accept it (Queue Roger Penrose). However, I see that it is comforting because life can go on, but I can also see to your point how it is terrifying because some of us could just merely be tired of popping in and out of existence. If reincarnation truly exists (I'm hoping for that to be true also), then maybe we just think of it as a long sleep between the last breath of our current lives to the first cries of our next lives when we are reborn. We don't want to continually be reborn, but we also don't want to be trapped in a void forever. Existence and consciousness are both just too precious to seize to exist because we don't want to continually experience the realm we are inherently living in, but we don't want to leave it behind either. I'm sorry that it went this long, but this stuff was plaguing my brain a lot, and I wanted to get a lot of this off my chest.

[@daigomasculinidade]

I have heard another theory, that, after the big freeze or big rip, when there's nothing but the post-proton decay hanging out there, there is a chance that matter could spontaneously rearrange itself on the quantum level and create matter out of nothing. There's nothing to stop it from happening right now, in fact, but in a near-infinite amount of time after the big (ending), the unthinkably improbable occurs and enough matter accretes in a single place to re-form a singularity and...pow, it all happens again.

If there was matter beforehand, there was something, not “nothing” as you so claimed. For there to be “nothing” before let’s say our own Big Bang, it would only be the work of a God who is eternal, the creator of “beginnings”. But your logic is not wrong, I’m just asserting that there was a point in time where there was literally nothing, nothing to feed off, attract or pull itself into energy/mass by chance to create a singularity or explosion of matter. This is how science brought me closer to God.

We're born out of cicles, and so do the universe, the big crunch is my favorite theory so far because exemplifies that, either way I don't think the universe will die in a dramatic way without hope for a new life, rather in a beautiful way, giving birth to a new universe so he can continue the cicle.

[@RoderSTatsTV]

Recommended: The end of the universe.

[@jcasetnl]

It's odd to me that in cosmology there is still a fear or resistance to the idea of "death". Everything else we know of the universe has a beginning, middle and end, but there seems to be a strong desire to view the universe itself as some sort of perpetual motion machine.

[@durkadurka5503]

Perhaps that’s just the way matter truly is. It’s often toted that conscious beings are are “sensory organs” of the full universe. This way of thought ties us all into the fabric of reality, where there’s no separation. Maybe the fear of death isn’t a simplistic consequence of how we evolved to persist, but rather we’re expressing a fundamental feature of existence itself. Maybe existence inherently “wants” to be.

[@familieehrenfeld9123]

@@durkadurka5503 it does. It is beautiful. It is sensory. That is what makes existence beautiful, being sensory. It dies, to be born again and every time it is undeniable magic, experiencing at sensory levels. Can we ever learn to protect the magic of being, of knowing, of experiencing?

@@familieehrenfeld9123 It's not always beautiful. Nature is very cruel and most of humans suffer a lot.

[@MrInuhanyou123]

The resistance to a definite end of everything is reasonable just because of human fear. It's because the big bang happened to begin with that started our universe. What existed long before that to even make such a thing possible and why would that be the only time such a thing could ever happen?

[@cablecar10]

Our universe is soup and someone left the burner on high 😔

[@gtifighter]

My own theory is a bit different, more dramatic and takes something into account, that many often don't realize. During the Big Bang, in order for matter to be created, the Energy that existed, created one part matter and one part antimatter. Now in our existing universe, only a tiny fraction of the original matter is left and all that exists now is what survived that matter/antimatter annihilation. Now picture this: What if through this matter/antimatter annihilation, some of the remains of the matter and some remains of the antimatter drifted apart creating two universes, the matter universe and the antimatter universe. Since matter and antimatter attract each other, these two universes are bound to collide at some point, annihilating the remaining matter and antimatter leaving only energy left at one tiny spot, waiting to explode and burst into matter and antimatter again.
