ps cd if i may..until science can tell exactly what the unimatter we float about in is made of exactly,your question to how and mine(to why not all the time ,with populated planets popping up left right and centre ) is only ever going to be unexplainable.

God is as good a word as any to describe that unexplainable and also to reason the drive and desire to find out imo,been around to give faith in scientists to search for answers long enough.

.

I suggest that the answer to your question without discussion not including variables is ...god  knows lol we certainly don't

So that was a quick thread wasn't it.
