    Similarly the start of time too? It's equally senseless to ask what existed "before" big bang. Something that people ask to claim God existed before big bang. Interesting thing about that is that it presupposes time as something even more primary and fundamental than the God itself.

    Well time is sort of weird - by relativity, time slows down in areas of higher density - this is a well proven phenomena that we can see experimentally. Taking the density to its extreme you'd get to a point of infinite density and therefore infinite time. However it's doubtful that such a place actually physically exists - so the answer is, we have no idea what happens when things are that dense.

    For as long as there is limited overs cricket - of ten, twenty or fifty overs - there will remain the Sri Lankan spinners' mid-innings choke

    Yea, it's doubtful that such a place physically exists (e.g that you literally get to a 'point' where you're dividing mass by a volume of zero). It's an example of how our current physics breaks down - because our physics tells us you reach a point where you're dividing by zero, which is not likely to be true in reality. We need better theories.

    Hm, something that really gets me is that if a single law of physics, no, of science didn't exist, nothing would exist. That is what really makes me believe in God.

    Any single law, we need every law in the universe, otherwise this universe wouldn't exist. For this to happen purely by chance isn't possible, no?

    I don't really understand the statement. I don't know a single law without which you can't have a universe.

    Changing of a particular law might change the nature of the universe but that's definitional (eg assuming we are defining the universe by the laws with which it's governed).

    Watching Wonders of the Universe yesterday got me thinking.

    Assuming you could travel at an infinite speed, and catch up to the edge of the expanding universe, would you crash into a wall or what?

    A sign would tell you to turn around.

    No. Or at least if there is such an edge, we don't know anything about it, even theoretically.

    In 2-d space, think (flat) ant on an inflating balloon. The use of the word "infinite" opens a can of worms.
