Yes, I know RightWhale. And so is extraterrestrial life. Which i think is funny in a way: We seek out other universes before we even understand our own, and extraterrestrials when we haven't got any evidence that they really exist.
I have an astrophysicist friend who insists the Big Bang was the result of a vacuum fluctuation, meaning that the vacuum pre-existed the space-time continuum of the physical universe. No "ex nihilo creation" for my friend! Of course, his observation is totally unfalsifiable, and therefore would not qualify as a "scientific statement."
But cosmology is a ton of fun anyway. :^)
Thanks so much for writing!
The negative vacuum pressure will produce equal amounts of bosons and fermions in several stages, which will exist for a while {a few trillion years in our solution state} and then collapse only to start over. Kind of like breathing.
