age of Universe
@ Mark 85 : "Maybe Douglas Adams was right ..."
... and the Universe was not created at age T=0, but, say, at age T=1µs, after the cosmological inflation and when matter has already been formed. Would solve 2 fundamental questions about cosmology: symmetry matter/antimatter, and size of the Universe.
Of course, that would also prove that God exists, which is a dangerous thing to do. And that would raise the question about who created God ... a meta-God ?
