I am neither a physicist nor a philosopher. However, your post did
remind me of my impressions when I read "A Brief History of Time" by
Stephen Hawking. If I may briefly quote:
Einstein once asked the question" "How much choice did God
have in constructing the universe?". If the no boundary proposal
is correct, he had no freedom at all to choose initial conditions.
He would, of course, still have had the freedom to choose the laws
that the universe obeyed. This, however, may not really have been
all that much of a choice; there may well be only one, or a small
number, of complete unified theories, such as the heterotic
string, that are self-consistent and allow the existence of
structures as complicated as human beings who can investigate the
laws of the universe and ask about the nature of God.
Even if there is only one possible unified theory, it is
just a set of rules and equations. What is it that breathes fire
into the equations and makes a universe for them to describe?
Is Hawking commenting on your question?
