What do you think will happen to the Universe? How long will it be until it ends? or will it go on expanding for ever?
Yes, I have considered the cycle it will create. But you have to admit that there are several versions of cycles in this universe. Furthermore, the fifth demension+ will be effected too. After all, such a demension is a "curled" demension. As Stephen Hawking puts it: if you look at a single hair, it appears to be only 1D. But, when you magnify it, the single hair is composed of 3D molecules. It has demension, and the demension is viewed through a variable magnification.Originally posted by Sensei
Why assume it will end? even in a big crunch... there may be repeat cyclings to the big bang again > big crunch > big bang > big crunch sequence.
If we lived long enough to witness the big crunch (if it happened) i wonder if we could survive by hiding temporarily in a fourth or fifth dimension...
hmm... too many questions, such little technology.
Isn't the big rip the same as the big crunch?Originally posted by Zefram
I'm going to go out on a limb and say Big Rip; c'mon dark energy!
That doesn't make sense to me. Why do you believe it is tenable?Originally posted by Zefram
No, the Big Rip is the result of the expansion of the universe continuing to accelerate until eventually everything in the universe is literally ripped apart. The exact opposite of the crunch.
Then the possibility exists that it might be very unhealthy to flee in them, don't you think?the dimensions, unlike the hair, may be subject to different laws than we are aware of at the moment.
Suppose the acceleration never ceases? I'm not saying it's necessarily the most likely end of it all but it's an interesting possibility.Originally posted by MajinVegeta

This sounds a lot like the Big Crunch to me.The first explosion
Caldwell's study had humble beginnings. He and his colleagues, Marc Kamionkowski and Nevin Weinberg at Caltech, were considering how a sphere of matter collapses under its own weight to form a galaxy. In computer models, they tweaked with the dark energy factor and found that too much of it would actually prevent the sphere from collapsing. In extreme cases, the sphere exploded.
1. Not really. Instead, they started off theorising on the big crunch, but found that if they theorised that the dark energy (the thing that is apparently causing the expansion of the universe to accelerate, not to slow down) is increasing, we would rip matter apart.Originally posted by MajinVegeta
I enjoyed the article. But it didn't make me change my mind about the big rip.

Secondly, what rips the matter apart? The dark matter or the phantom energy (is the phantom energy, since the article related it with the cosmological constant)?
