Hi:

What happened before the big bang?

Sadly, its a question that can't be answered, yet its so interesting.

Something like this question may be answerable. Time is a property of
our universe, and it began when the universe began, so the concept of
"before" isn't easily defined. However, if theory and experiment
ultimately support the existence of one or more hyperuniverses, then the
_cause_ of the Big Bang in that larger context could be understood, even
if "before" isn't exactly the right way of putting it.

well,
if the universe expands and then contract,then BB again,etc,
then there was a time before,because by contracting the time might go
backwards,yes?
IOW,when space is contracting time must contract too,because it's part of
spacetime
yes,or is it no?
just a thought,

marten
