"While we are talking about "crazy" things, how do they know that 10 picoseconds after the Big Bang – electromagnetism separated from the other fundamental forces??"
Uh, maybe someone was floating just outside of the universe and watched it happen then passed it down all these billions of years, Makes about as much sense to me as someone stating there is no possibility there being other universes or that one moment there was nothing and in the next moment BANG the universe appeared out of nothing.
