i like the fact if u stand on earth and wave into space, then go jump in a spaceship and travel faster than the speed of light and look back you see yourself waving

I'm afraid you cannot see into the space the universe is expanding into, that's impossible because there is nothing there, no space, no time, nothing.
As matter (universe) expands, it creates the space and time in the void it moves into ...... classical theories had the big bang causing this expansion, which seems pretty reasonable to me when you look at all the evidence.
The problem being, did we expand forever or were we gonna slow down and gravity pull us back in again just as a ball slows down and comes back to earth when it's thrown up in the air ...it accelerates for a time and then decelerates as the effect of gravity pulls it back.
When cosmologists looked at the expanding universe, I think the expectation was one of a decelerating fringe but I'm afraid this wasn't the case....the problem here is, if we are accelerating, then it means we are doomed to become a lifeless cold, extremely cold universe.
I quite liked the idea of us coming back together in a big crunch and maybe reborn again ...... I like it because it has symmetry.
And the notion that all the world's matter and energy can be compressed into a sphere the size of an atom (just before it enters the singularity phase that mathematicians and astrophysicists love soooo dearly) does my ole nut in big time......think about it, ALL the world's matter compressed down to that size ...it's mind numbing.
It's so mind numbing in fact that at this stage of the game where mathematicians and astrophysicists are struggling for breath, a door opens up and in steps a bunch of philosophers to take over the debate ......blimey, ya know all is lost when they get into it...those guys can disappear up their own ass and still declare they have found the truth of the matter (pun intended).
Whatever the case, the jury's still out in terms of what happens after the big crunch but at least we won't be around to worry about it anyway

Your joking some of the English on here is hard enough to read....If anyone speak Norwegian I can go on alot more about the subject, I'll have to read up on the English terms
I vaguely remember reading some stuff in new scientist which was along the same lines you're describing Robbo. It was likened to the effect of a glass of water being poured onto a table. Unfortunately when all the matter is spread out far enough it is theorized that it'll start to tear itself apart, starting with large objects then finishing with little objects. So in theory, if you were in a spaceship when this happened you'd be able to watch Earth be torn asunder before you yourself were pulled apart at a molecular level I also vaguley remember something about the universe being donut shaped, but then it got all quantum on my ass and comprehension left me. I'm happy to wrack my brain about my own little microcosm without having to understand the really big questions.

The only 'tearing apart' I know about is when objects (suns, planets, whatever) get pulled into a black hole.I vaguely remember reading some stuff in new scientist which was along the same lines you're describing Robbo.

If the universe carries on expanding, I don't think there will be any tearing apart as such, more the spaces in between stars, black holes and planets etc increases and as it does so, the universe becomes cooler ..eventually, all the stars will burn out and leave us a lifeless, cold lump of nothing.
Still, Coronation st is on this week ...we can watch that
Actually no, I don't watch anything like that at all, i was just being silly.....I'm afraid me and the TV don't meet up a lot except of course when Spurs are playing or there's a good science proggy on, Horizon on BBC has lost the plot lately and its standard of productions is pi$$ poor compared to what it used to beYou watch Corro? You bad, bad, bad man!
Oh, I do watch 'Everybody Loves Raymond' and some 'Frazier' though, they make me laugh but that's about it .....
