[QUOTE=Falubii;38692392]Ah, you're referring to this [url]http://en.wikipedia.org/wiki/The_Black_Hole_War[/url] I thought you were trying to say there was a debate over whether or not Hawking radiation existed at all.[/QUOTE] Figured that was probably the confusion.
[QUOTE=KorJax;38690342]What exactly is the big rip? Why will it happen if the universe expands if the universe is just some term we use to explain a collection of cosmos in a vaccum (versus the vaccum, and the "universe" itself, being bound together somehow). It just doesn't seem likely that the universe would have a similar reaction to cloth ripping when over expanded, considering its a totally different thing entirely and we have things on earth that never "rip" when expanded.[/QUOTE] As the rate of expansion of the universe gets faster the cosmological event horizon (the distance at which objects are receding from us faster than the speed of light, so we can never interact with them) shrinks. Eventually the distance to the cosmological event horizon at any point in space will be less than the distance between atoms in molecules, so molecules will break down and never be able to form again because the electromagnetic force, travelling only at the speed of light, won't be able to reach other atoms because the space between them is expanding faster than light. As the horizon further shrinks atoms themselves will come undone, as will protons and neutrons eventually. Scary, isn't it?
Nah, it's not scary. It's neat. [editline]3rd December 2012[/editline] Call me weird but when everyone's like, "HOLY SHIT A 17 BILLION SOLAR MASS BLACK HOLE IS GONNA EAT US NATURE IS SCARY" I'm like "Nah, it's too neat to be scary." Even if we were being sucked toward the event horizon right now I'd be like, "Shit, this is neat."

That the cosmological event horizon will inevitably recede in on everything and slowly the universe will become a darker, smaller place. Hopefully something else will happen from that point on, though.
[QUOTE=MrJazzy;38699779]Even if they do what the hell are we gonna do about it... it's not like we can run away from a black hole.[/QUOTE] Well we actually could. Black holes aren't cosmic vacuum cleaners, you can orbit them just fine. We'd probably end up flying away when it became an actual danger.
[QUOTE=Sgt-NiallR;38700507]Well we actually could. Black holes aren't cosmic vacuum cleaners, you can orbit them just fine. We'd probably end up flying away when it became an actual danger.[/QUOTE] But then we'd die from something else I'd guess, though my point is that we have no control over it.
[QUOTE=Sgt-NiallR;38700507]Well we actually could. Black holes aren't cosmic vacuum cleaners, you can orbit them just fine. We'd probably end up flying away when it became an actual danger.[/QUOTE] We're orbiting one right now.
