@immisukkas If the current popular theory is correct, the universe will keep expanding forever due to dark energy. Also, it's not that humans aren't able to perceive, is just that according to calculations, right before the big bang, the "universe" was infinitely small. Zeno's paradoxes (there are 2 other similar ones to the one you mentioned) have been solved as far as I know, with even several solutions proposed.

I understood the first 18 seconds. hmm, may be a beginners guide, but not a TOTAL beginners guide (idiots guide).

@khaghgoo what do you mean?

[immisukkas]

@Xxthefckxx What if there really wasn't a beginning? Space-time expands and contracts, right now it's expanding I believe? What if the universe was just sooo incredibly tiny and contracted ~14 billion years ago that scientists and humans simply can't perceive it and said that around 'here' it started. It's like that paradox where you take a step towards the wall and half that the next etc you'll never reach the wall :)
