So how will that new Big Bang work? By that point the Universe will be insanely huge, cold, empty, and dark. AFAIK, the big bang required the complete opposite of those conditions.

There are several possible models for the future of the universe:

I'm not sure if there's a consensus among scientists about these models, or if they don't have a clue at all, but the first model would result in a new big bang.

It relies on how exactly dark matter and dark energy work, which are responsible for the expansion of the Universe, and its rate of expansion. Problem is, no one knows much about dark matter or dark energy

The thing is, a big bang doesn't need time or space anyway. It creates that stuff by itself.

Also, compared to an infinite amount of time, the number posted in the OP is still small.

It's because of this part of science that I fully understand why some people just choose to believe in ghosts and goblins instead.

Alby_da_Wolf said: To put it simpler, 10^560 simply is (10^10)^56. 10^10^10^56 is wrong anyway, 10^10^56 could be right or wrong depending on the convention used, ambiguity could entirely be avoided if normal text editors allowed multilevel apices and subscripts. We should ask that wysiwyg editors and word processors from now on were based on LaTeX. Or use professional desktop publishing tools, but I guess LaTeX and LaTeX-based tools are the cheapest way to get that power.

It's not. I mean it is, but the OP made a mistake and we're thinking about the wrong number.

(10^3)^4 = 10^(3*4) = 10^12

(10*10*10)^4 = (1000)^4 = 1000*1000*1000*1000 = 1,000,000,000,000

but the number that the op meant to refer is not actually structured this way.

It's supposed to be structured like this:

10^(3^4) = 10^(3*3*3*3) = 10^81. This would have 81 zeroes, not 12!

The number that was originally meant to be posted is far larger than 1 followed to 560 zeroes.

Dont use drugs kids!!! =)

For people saying the number only has 560 zeros, it doesn't. The super large number that I posted represents how many zeros are in 10^10^10^56, and that number itself has 560 zeros. I know most people didn't want to count all the zeros, so I put it in there so people could understand just how large it is. 

Yes, its a really fucking big number, much larger than 560 zeros.
