another philosphical Q. i make notion that from what we have learned over the life of humans, is that we dont know too much, and for some things we were just wrong. i ponder this Q, why do we write The Big Bang at time=0 as a very small point that contains all the mass of the universe. cant it just be an "event" in an existing space/time fabric, as example, perhaps two super-duper-massive black holes eating each other and the result was the release of observable mass/energy? basically an energy converting process that converts lots of dark energy into non-dark energy ??
