Default When our universe dies...

what do you think will happen?, do you think its like a cycle and everything will starts all over again with another big bang

Observations indicate that the Universe will not collapse, and in fact the distance between most galaxies is increasing. This seems to indicate that this, regardless of the possibility that there have been other universes (I have no opinion on this.) this is the last time around. The universe should never really die, but it will become rather uninteresting. Entropy will wear everything down untill energy is evenly distributed across the universe- you'll probably have an endless, unchanging void full of microwaves.

will all life die out

this is what i think, the universes die but the multiverse will not, multiverse consists of never ending universes jsut floating aroung birthing other universes

I personally am still hoping that the universe will contract back into a single point. I know evidence doesn't look good for this, but I'm still hoping. If this is the case, theoretically there could be another big bang, and it would all happen again. In fact, if that were the case, this process could happen an infinite number of times. Thus this could be our millionth time doing exactly what we've done before. How crazy.

Yeah, sorry. Seems pretty likely that it ain't gonna happen. If it makes you feel better, if you believe in the multiverse than there must be an infinite number of people infinitely like yourself. And if there's an infinite number of 'em than one must be president or galactic supreme emperor or something. Actually might there be an infinite number of GSE yous?

i heard that everything is distancing themselves from everything (because the universe is expanding) that one day when we look up in the sky (if were still here) we would see nothing because the stars are so far away, is this true?

Eventually, all the stars will die, so you won't see them anymore. But in addition, if the universe is really accelerating, than eventually the rate at which the galaxies are flying apart will exceed the speed of light. At that point, the galaxies either vanish, or what they look like never changes again. I forget which.

I live in a city all I see when I look up is pitch black if I am lucky, perma-noon if I am not. So I guess I am ready for the end of the world.......

The galaxies are currently accelerating away from each other. Eventually you won't be able to see galaxies, just the stars in your own galaxy.

Star formation is on the decrease, so eventually no new stars will form in any galaxy. They'll all burn out and become long-lived white dwarfs.

Then the supermassive black holes at the heart of galaxies will consume all of the material to form a single, galactic-mass black hole.

According to Hawkings, the black holes will then evaporate one atom at a time until the Universe consists of an elementary mist of particles accelerating away from each other.

Have a nice day.

Anybody know where I can get reservations for the Restaurant at the End of the Universe? Seems like something that I'd like to see... :wink:

The so-called Big Rip theory claims that repulsive dark energy becomes exponentially more powerful all the time. In about 20 billion years in future it will rip the whole universe apart.

Here's the timescale:

- 1 billion years before the Big Rip: galaxy clusters lose their galaxies
- 60 million years BBP: galaxies start to break apart
- 3 months BBP: planets leave their home systems
- 30 minutes BBP: stars and planets blow up
- 10^-19 seconds BBP: atoms dissociate
- 35 Gyr after Big Bang: the Big Rip, space-time break apart

Pretty scary!

I guess none of you read Asimov's novels... He said that a super computer living in hyperspace will eventually find a way to reverse entropy, halt the proton decay, revert energy back into mass and compress the universe until another big bang occurs... Which all takes about seven days.

the energy of the cosmos will slowly begin fading, ultimately burning out completely. Stars will stop forming, life in the universe ceases to exist, leaving the universe to return to its pre-big bang state - a true vacuum.

All matter will eventually wind up in a black hole (not a single black hole for the entire universe), from which it gets released as radiation, leading to heat death.

I'm surprised nobody mentioned Paul Davies' 1994 book The Last Three Minutes, Conjectures About the Ultimate Fate of the Universe, (which is a clear take-off of Stephen Weinberg's famous and highly recommended The First Three Minutes). The Last Three Minutes is a whole book that discusses the question posed at the head of this thread.

Everyone knows of the basic material in which the universe is comprised: you have your quarks, which manifest into Byronic material like protons etc; and your leptons, things like electrons, positrons, and neutrinos; also, there is dark energy, dark matter and many other beasties that are well known, and perhaps not well known.

Well none of you know the complete story, until now.

As we all know energy is conserved.

But did you know that there is an exception?

Thoughtons! Yes! The only mass/energy never used in calculating the mass of the universe. Thoughtons can only be generated by biological beings which are sentient. Undetectable at this time because the universe is still sentiently uninhabited.

As men, and all the other aliens, populate the universe the thoughtonic energy will increase to such a point that all of the impetus for the infinite expansion of the universe will be overcome by gravitational attraction: the pull of baryon material, dark matter and ---of course---thoughtronic attraction.

The end result will be a Big Crunch. At that very last Bohr second the omega point will happen and we will all exist for a brief bit of time which will seem to last forever. Heaven. ops: :-({|=

Not bad =D>

But most thought processes probably boil down to a complex series of electrical signals turning on and off in sequence, being interpreted by the receptors in your brain...nothing more than a complex computer. How does this transfer to a new form of energy?


This whole thread reminded me of this site (http://www.xs4all.nl/~mke/exitmundi.htm), pretty cool stuff.

That's a comforting thought, but why should there be other universes?

well ... may be not completely black.
perhaps some residual microwave radiations at 0.00000....0 1 K or so ....
