There are theories that suggest that the universe will cease to exist one day. Such as the "Big Freeze" theory among others. It might possibly never stop expanding, though I would say the knowledge we have so far suggests otherwise.
So what do you think about it?
-
As individual bits of matter then each must become something else but as the universe is more a concept covering the idea of a container I don't think that it really can end. Should it die with the end of that concept, of universe, then maybe but the overarching actuality of a universe has to go on in existence if not in concept and if it must die then I think philosophically that's a reason that and balanced scientist must take to begin to explore creator ideology because the universe then begins to become a tool.

I agree with the Big Freeze theory. It's doesn't look like the Universe will stop expanding and probably one day interstellar matter will be so spread out that the formation on protostars will stop and Universe will go dark.

I'm thinking a super black hole and when everything is sucked up another big bang will happen.
-
Badly.
-
Isn't the universe constantly speeding up, and eventually it will expand enough that dark matter gets inside inbetween atoms and rips them apart?

Reapers

Heat Death, depressing as it is, seems to be most likely. However, I also believe that it's quite possible that another Big Bang will occur after the end. It did happen once seemingly out of nowhere, with seemingly no reason. That, and I like the idea of a never-ending, cycle of creation and destruction. Keeps things interesting. Especially when you begin to wonder, if the universe rebirths after death, just which time around are WE on?

Not with a bang, but a whimper.

No idea, but based on our previous cosmic experiences, spectacularly, with lots of colour and light and sound and light and noise and explosions.
-
I don't think it will end.
-
I like the Earth slowly orbits into the sun theory.
-
Heat Death/Big Freeze has the most evidence in favor of it.

Edited by Ozzy Onya A2Z: 2/4/2013 3:28:55 AMI like to think of things as infinite and similar to bubbles if you will. Take each big bang as a bubble and then throw in a mix of variety, distance and timing for good measure. Some expand and pop, some shrink back down, some join together and it's a continuous ebb and flow just like most things we observe. I'm yet to observe or read about one singular unique thing, entity or observation which is why I like to follow the bubble theory so to speak. How does that relate to our bubble (universe) ending? It could expand and then pop spectacularly or it could just shrink back down to nil. It would be cool to join with another bubble (universe) but the collision will wipe us out anyhow. I have no idea how things will end but I feel comfortable that bubbles over time and distance will always be present and give rise to many forms of life. We just happen to be at a great time of learning and technology in our own bubble. I hope to see some interaction of those bubbles/life forms in my time here but I do not think it's probable. Bring on the crazy light show for my ending please, at least I'd have good seats to watch from :)

Heat death, leading to homogenization, equalization of entropy, presumably forever. When the Universe is so homogenous and entropy ceases to increase, there will not really even be any way to measure time. The Arrow of Time will continue "forward", the Universe will continue to expand, but there won't be anything past virtual particles in the mix. I personally don't put any stock on Renormalized Virtual State (and its inherent principle of infinite probability) which states on a long enough time scale, virtual particles will make another hadronic Universe. That sounds like a typical renormalized probability trick to me.

Anshent assonawts.

The Big Stroke. It's really just the universe having a stroke, but if I put "big" before it, it makes it a valid scientific theory.
-
The big rip. Eventually expansion will grow faster and faster, until it effects even the bonds that hold atoms together. Then the particles themselves right down to whatever they are made of.
-
Is there a world outside the universe ?
-
The universe as we know it will end (drastically change) but it will never cease to exist.
-
The big implosion...

it will gracefully doff it's hat and depart when the best of the entertainment has passed
