Hi, > Naive question: do physicists reconcile a "really flat" universe and > the big bang theory? I don't see how.
you mean this problem? http://en.wikipedia.org/wiki/Big_bang#Flatness.2Foldness_problem Inflationary theories give a solution, but it is a bit ad hoc. I am not a big fan of Big Bang - I like Paul Steinhardt's (not Eric Steinhart) cyclic universe, but I have not read enough about that model to know if it fares better explaining cosmological observations (but it is _compatible_ with current observations). But those reflections are from before my MWI times ;-) MWI explains fine-tuning (but not flatness) due to the anthropic principle.
