Re: “Riddle me this . . How can one go from a 'point in space' with no matter to this 'Big Bang' vomiting all manner of matter components - enough to make a Universe worth of matter . . . ? ? ?”
You should watch the videos fizzy posted. They cover this better than I can.

Penrose believes that before the Big Bang, the universe was in a state of thermal equilibrium. Consequently, things we take for granted did not exist. One of those is the concept of SIZE. If there is no size, then your 'point in space' reference ceases to be an issue.

Ironically, in the distant future when all matter 'evaporates,' the universe will return to a state of thermal equilibrium, and the very, very big universe will be no different from the very, very small pre-universe that spawned the Big Bang.. That sets the stage for a repeat performance... but maybe not an EXACT repeat.
