From Chris Ford
It always surprises me that there are scientists who can’t accept that time and space began with the big bang (5 September, p 30). They succeed only in pushing the problem further back. You must accept either a beginning at some point or an infinite past, with all the horrors that infinity implies – everything possible has happened an infinite number of times. Infinity always spells the death of reasonable physics. I suppose we could all be whizzing infinitely round a closed loop, but that sounds just as bad.
Personally, I’ll stick with the good old big bang – everything has to start somewhere.
