...a trillion years, give or take. Not a glimmer of light. Everything in the universe will be extinguished. No supernovas, stars, neutrons, planets, no explosions, nothing at all. So says the narrator at the end of a BBC 4 documentary I just watched.

The big bang was only around 13.8 billion years ago, so a trillion years (a thousand billion) is still a fair way off. I'm only posting this to say, it seems unbelievable to think that eventually no life will ever exist. If that is the case, it does make me wonder, just how important is life if it can be snubbed out seemingly forever, even a trillion years from now?

Or, does anyone think another big bang would probably be triggered again?
 
I always thought that the heat death of the Universe was way further into the future than a mere trillion years, something nearer to 10^100 years.
 
We'll be burned to a cinder when our sun turns into a red giant well before then :/

I'd like to think big bang is recurring cycle.

there have been various theories about the universe ever expanding etc... what one guy says its his view.

How many trillions is that then?

All get sucked into black holes maybe? The universe effectively disappearing up it's own ****

But stuff comes back out as hawking radiation. Effectively the universe farting itself.
 
We will either wipe our selves out in a couple hundred years (id say less, humanity is a destructive species), or moved away.

Also like to think this universe thing is on a cycle. Expanding into nothing, shrinking back down, then expanding again.
 
What documentary? Was it a newly recorded one or a re-airing of an old one? Recently astronomers have found out new information and they've come up with new theories which mean the big bang may not have happened the way we previously thought. This kind of research is constantly evolving as new information comes to light from new observations as data is gathered by all the probes and satellites we have in space.
 
Yeah, that's the universe heat death theory which assumes there's no big crunch or anything like that.

Nevermind that though, with the constant expansion of the universe at some point you won't be able to see any galaxies or stars bar the own in our local cluster because of them moving away faster than the speed of light!
 
That is assuming our technology does not improve millions of years from now :p

In that time we could have a completely different and new understanding of "time", telescopes may be made of worm holes and capable of seeing from one end of the universe to another.

None of this can be called strictly SciFi any more either, which is the most amusing thing about it all.

We'll most likely all be dead, to be honest. Humanity is showing it is very short sighted and may not survive the next millennia.

One argument also against FTL civilisation is the simple question: Where are all the advanced aliens? It's dead out there, which isn't a good sign for that. All conjecture but worth weighing up.
