Does it "matter" Pete? :^O

We're told the Universe is 13½ billion years old (give or take the odd billion) so if we're talking about the Universe as we know it, where the matter came from for the original, original, original..........et al...... Big Bang shouldn't really concern us?

The age of the Greater Universe may be infinite for all we know or have any chance of discovering?

Like I've hypothesised, "our" Universe may be only a "small" corner of the Greater Universe, a "place" where Big Bangs come and go every now and again?

For all we know...... the cause of the movement of our Universe "speeding up" may well be that it's all heading "out" towards a series of gigantic Black holes which will eventually consume "our" Universe before, one day........ causing another Big Bang or series of them.

We just don't know and owing to the vast distances involved, are we ever likely to find out before some catastrophic event (Like a super-massive Coronal Mass Ejection from our own Star?) destroys us and all life on this Planet?
