Do you believe the end of the universe is when it reaches absolute zero?

Question

The big freeze is probably the final state of our universe wouldn't you say? It all has to do with omega and lanbla. Anyway, there's not enough matter & energy to reverse the original expansion of the universe so it will expand forever like its doing now. What's your ideas on how the universe will end?

Answer 1

Best scientific evidence we have, particularly the data from the COBE and WMAP missions, indicates that the space of the universe will continue to expand indefinitely, even though the time will probably come when it is an absolute vacuum without light or matter of any kind.

Answer 2

I don’t believe that the universe we know and see will end when it reaches absolute zero, partly because, in theory, absolute zero can never be reached (only approached asymptotically), also, absolute zero is a thermodynamic model and matter would still exist (just no heat).

However, I am impressed with the explanation that angeltear757 provided above, but I’ll modify it to reveal another perspective.

The universe is “expanded” around a massive black hole The black hole slowly swallows all the matter that's drawn into it's gravitational pull, until it gets to a point (supergravity), where all space and matter are embedded in that black hole. Although, my version now changes from the cyclic version that angeltear757 had suggested, “where until it gets to a point where it basically vomits everything back out again in a violent outburst” (this concept is one many theoretical physicists/cosmologists would probably make, so good for you angeltear757). But then again, the universe we see is currently thought to be in a broken symmetric state, and the universe would return to supersymmetry, which would be a supergravity condition, and would have a single point of force that is so massive, that I predict it would not break symmetry again.

Again, angeltear757 has a good question along with yours that initiated this post, ZORRO. Which is: “what's beyond the universe it's self? There must be something else right?” This is where I predict that the universe is currently in a dual state (duality), both supersymmetry and broken symmetry are co-existing as “supergravity and universe.” What we would lose is the broken symmetric state of things, and return to a state like the moment before the big bang.

What the “something else” IS, as I see it, is: Supergravity would not break supersymmetry again, unless there was another force which intentionally decided to break supersymmetry again (using randomness). The key word here is “intentionally”. To answer this bigger question, we would expect that if “intention” caused the universe to break supersymmetry, then everything in the universe should be embedded with intention.

Here is my question to you ZORRO, angeltear757, and everyone who wants to use the scientific method to prove whether the universe was intended or not!

Can any of us perform any experiment, document any experiment or do anything (like make questions or read these answers) without intending to do so? If your observation and result is no, and you can also reproduce this result and predict that everyone who will do this in the future observes the same results, then perhaps there is something else. (if your answer is yes, then you did not intend to say yes)

My ultimate answer for you ZERO, is, I think you are correct, the universe will expand forever!

Answer 3

Well, there are actually two extremes and two conditions under which oine might say that the universe has ended--but all the matter will still be there in some form or another, so the universe will not end. Universe means something like "unified" and thus needs matter in some form of organization (like planets, suns, galaxies). So, the universe "ends" when there is no organization or no motion, but the matter remains.

That said, the two conditions under which there could be said to be no universe (no organized matter) are: (1) if the whole darn thing cooled down to absolute zero, for then all motion ceases; and (2) if it heated up to unimagineable levels such that no particle, no quarks, no anything, could interact with anything else, where everything is in a massive state of disintegration (this could also result in absolute zero conditions).

So, massive disintegration (disaggregation) and massive compression (like the grapefruit-sized compression state of all matter said to exist before the big bang, assuming again that the big bang is a legitimate theory of origins) are two conditions when there would be no universe. Either or both of these could occur under conditions of absolute zero or massive heating, I think, though some people may say that absolute zero is probably more allied with massive compression and great heat with massive disintegration.

A last comment--this has nothing to do with belief, with with hypotheses, tests, and evidence. Beliefs have nothing to do with evidence, facts, tests, or hypotheses.

Answer 4

It's been to my understanding that ...i'm hoping i get my termonogly correct, i've had no formal training...universe? is centered around a massive blackhole. The blackhole slowly swallows all the matter that's drawn into it's gravitational pull, until it gets to a point where it basically vomits everything back out again (i would imagine in a violent outburst, much resembling an explosion) then begins the binge and purge process all over again. So, instead of expanding forever, or reaching absolute zero, it may actually be in a perpetual cycle.

At least on the bright side, everyone on the planet will be dead before we're swallowed by the blackhole at the center of our universe becaus the sun will burn out long before then, engulfing the closer planets and turning earth in to a ball of soot before it's final implosion. :)

What i don't get though, is what's beyond the universe it's self? There must be something else right?

Answer 5

Yes. But if you are talking about the matter in the universe, absolute zero is a really strange state of matter, but as far as I know, the matter would still be there. Just dark, cold, and in a very weird state. The thing is, if it's matter, it also has wave properties. Waved have energy (otherwise they wouldn't be called waves), so matter would not get to absolute zero. Now if all matter fell apart, if protons decayed, then things would truly end. They tried an experiment where they put a gazillion protons into a vast underground tank on the theory that at least one must decay in a gazillion years and if you have a gazillion protons, you should see at least one decay in a year's time. That didn't happen. So the end of the universe, if any, would be in a long, long, long, long, loooooooong, long, long^100^100 time.

Answer 6

that's some heavy thinking. i think about stuff like this sometimes. never really thought about that. i guess i don't really see it happening. the universe is supposed to be expanding now. if that is true why is our planet getting warmer. global warming maybe an answer, but we are moving away from the sun. is there anything at the end of the universe to stop it from expanding. i saw a really interesting thing on p.b.s. where they were talking about the string theory. alternate universes and things like that. i don't know why but I've thought about that for years. I've seen things off and on over the years that some people might call ghosts. maybe it's an alternate universe getting to close. they can split the atom, but what if they could split a second. two people could be standing in the same place but not stand in the same place. I'm sorry for rattling on .

Answer 7

see here is the problem. This new theory that space is going to continue on is crap.

These scientist are so eager to find the next big thing so there name can be printed in the next high school science book they conveniently forget the basics.

Light takes a very long time to get here. So, the light that they are seeing from 15 billion years ago should look red shifted. 15 billion years ago it was accelerating.

People, you will not see the universe crushing in on us until the moment of impact. The universe will collapse at the same rate as the speed of light therefore keeping up with the same light that we would otherwise see as blue shifted.

Answer 8

The entropy is getting greater each cycle, each time. The universe is ended up with higher disorder, according to the third law of thermodynamics. If you wish there will be a big crunch, it all depends on the dark matter and dark energy, are they enough to reverse the expansion of universe?

Answer 9

i think there will be enough energy and mass to reverse the expansion of the universe and a new big bang will occure

Answer 10

I believe the universe will be renewed by US before that happens. Sound impossible? So did so many things a few years ago.
