Scientists say even space did not exist prior to the big bang. Except,
perhaps for the space occupied by the infinitely dense singularity
from which came the big bang. Much smaller than a single atom they
say. Einstein said that our universe is finite, didn't he? Seems to me
that is a widely accepted view. I think my own concept of infinite
comes from the writings of Benedict Spinoza. Anything regarding which
nothing greater than can be conceived is infinite. If our universe is
all that there is then I think it could be defined as infinite.
