nitpicking, eh ?
*edit*
oops, that was directed to the posts above Stefan's
@Stefan: you mean, how did things emerged out of void ?
Time is just a dimension, like distances. The 4 dimensions belong to the continuum we all know. In this regard you cannot separate them and ask something such as e.g how did time emerge from void ; since this question would be irrelevant or at least very incomplete because hiding the fact that
not only time emerged from the void.
The key is to define void. It can sound stupid but have you ever wondered whether the absolute void, nothing, rien, nada, existed intrinsically at all ? Back in time, the
air was believed as void. Later on, the space - between planets - was believed to be the void. Now, it's what was beyond the big bang. I dunno what to think.
What is certain though, is that the big bang created only
antagonisms. Matter existed because of anti-matter, and energy because of what astrophysicians call "black energy". Time is nevertheless, like all dimensions, a distance that can be walked back and forth.
Let's not forget we can comprehend
only 4 dimensions in the Universe, and practically represent ourselves
only 3 of them at a time. What is above and beyond is subject to the craziest speculations. We're allowed to dream on!
