Last I heard our sun has 4 billion years left b4 radically changing earth environment

There's evidence (red shift) that the universe will continue to survive for at least as long as it has existed. The nature of the universe may change, but there's no indication that it will end.

According to Steve's Steady State Theory it already has.

Current models predict that the universe's expansion is accelerating and this will continue for roughly 15 to 20 billion years until the Big Rip occurs. If the acceleration is driven by space itself via something like a non-zero cosmological constant then space itself will eventually rip apart. That is, kinda the end...

Since we don't actually know if our models of the accelerating expansion are actually correct, it is wrong for us to conclude that this is in fact the fate of the universe. Though it is currently the best we've got.

I'll give it another week or so.

Chances are yes.

The Universe will be around long after we and any other living creatures in our galaxy are long gone. How long? I don't know. I don't know anyone who does know. I've heard some guesses, but those are all over the board too.

So, the definitive answer is, damned if I know.

Scientists who are far smarter than I am state that it will and I believe them.

There is a zero-point that will be reached--in the center of the expansion. It will be a "null"...the absence of space/time/gravity. The null will be the entry-point of another "Big Bang". Expansion/null/expansion/null. Sort of like the spark plug of a combustion engine.

Yes, but it is questionable if the earth will.

The universe , yes the earth, no. see so much good stuff like the Andromeda galaxy colliding with the milky way, its all a matter of time , when time itself will end, that's the end, full stop.

Sure, but near as we can tell it will end in heat death eventually. Although it's unclear whether that is really an "end" or just part of a cycle leading to a new big bang. Mathematically, time kind of breaks down at the extremes of the BB and heat death, so ... in that sense the universe may prove to be eternal, though, not in the form we now know it as.

Luckily we won't be around to find the answer.
