That is what current physics tells us. The laws we

Is that so? From current M-Theory a number of observations are being made
at
the state before the "big bang"; some give quite a possible understanding
of
the resulting interaction from the theorized multiverse and our universe.
Not everything is that speculative in these theories.

I think you mean "a number of predictions are being made"
unless you know of a way to observe condition "before the
'big bang'". The question is can those predictions be shown
to affect the region since then that is observable making
M-Theory testable, at least in principle. Last I heard there
were some ideas that looked as though they could possibly
have some influence but they hadn't actually come up with
specifics. Maybe you know of more recent developments.

IMHO, barring testability, M-theory remains speculation.
