You're right it is and was. Your post reminded me of an exchange where a turtle held the world on it's back. My apologies, I didn't know you were that serious. Here's some answers.
"So there was NO space, NO time, NO matter, and NO temperature."That's correct. There was only the other place, the vacuum. Folks can't go there, so they only as much of it as they can see from this world.
"Somebody please explain to me what medium this infinitely dense single point existed in. What was the fabric of the medium this point was floating in?"
The single point idea is only used as a mathematical tool at present by the folks in this world to understand things we see in this world. My understanding is that there was not a single point initially, but an occurrence in the other place, the vacuum, out of which this world arose. I don't know the physics of it. Something akin to the developement of a disaster wall in Physicists post #65.
"Where was it?"
As far as I've seen the universe appears to have roughly a crunched spherical shape. You could go back from the edge of the visible universe and locate a spot for where the initial creation happened, but you must realize there was nothing here originaly to say where it was. If you were in the other place, you would have a reference to say it was here.
"When was it?~15 billion years ago.
" It seems they are saying that NOthing suddenly became everything.
Out of the vacuum arose all that we see.
" What law of physics made this possible?
Don't know.
" How can there be any laws when nothing, no where, nowhen exists?
The laws we have in this world arose and are consistent with those in the vacuum. No one can go there to observe, or determine exactly what's there.
