Doesn't bother me at all. :-) May be the big bang was a really big bang :-)

All current theories break down at t=0 so I don't have any problem with this
one being shaky around that point.

How big is "infinite?" We cant (shouldn't) make any assumptions about the
universe before t=0 so why assume it was nothing?

At t=10^-35 the universe could have been very, very small yet infinite in
size.
