That's like saying you'll surely die of old age in "about a microsecond." I.e., you are off by so many orders of magnitude that you're asking the wrong question, several times over.

It's also based on cosmological assumptions based on far too little evidence, which is the mistake modern science generally makes even when it gets its math right. Not to mention the misinterpretations of people reflecting upon the hypotheses and conjecture of cosmologists. Or the imaginitive leaps of science fiction and TV documentaries.

hmm, I thought a billion years was about right before we could actually traverse universal barriers. Well maybe not exactly but the intent was that it would be a very long time.

If there are an infitite number of rooms, it'll probably take you an infinite amount of time to get them to change rooms. Oh NOOOooo...!

Entropy, cold death... if the universe keeps expanding everything will break down eventually.

Assuming that there were no unknown factors( which there most certainly is ), wouldn't gravity keep the universe from maximum entropy? Is there anything to indicate the universe wont just do the whole big-bang thing over and over again?

I also thought I read somewhere that they'd discovered that light didn't actually travel infinitely, but somehow bended back towards us when it had travelled for some time?
