100% cool NEUFER
If there is a God and if there is a heaven and I I were to go there when I die please God let there be a 1970's and 80's section but knowing how things usually go for me reincarnation will be the next E-ticket and knowing my dumb luck I'd probably come back as myself.
I've come to the conclusion that when i said i wanted to be somebody when i grew up i probably should have been more specific

I think that the universe may have appeared just like how a virtual particle appears and then disappears, except on a much grander scale.

Let's James Web Telescope speak. Maybe it will provide us big surprises

I think that the Big Bang did not start from a point
of infinite density, but it arose from a large amount
of cold, compact and high density matter.
Before the Big Bang there was matter.
But, what caused this explosion?
Possibly a series nuclear fission reaction, generated
the Big Bang

Right now, we don't even know if the Big Bang required a cause. But we do know that it didn't involve any nuclear processes, because at the time of the Big Bang, and for a discrete length of time after that, there were no atomic particles.

Just as a bit of play with universes and those exotic ideas of multiple dimensions, I imagined two high-dimensional bubbles intersecting, whose intersection 'circle' is our 4-dimensional universe. At first the intersection is an infinitesimal point; then, as the intersection deepens, it expands dramatically (the Inflationary period). Eventually it slows down, comes to a stop... before beginning to shrink, in a reversal of the previous process. Finally, an infinitesimal point marks the instant at which the two bubbles disengage and the intersection circle vanishes and they can float off on their adventures unknown. Or perhaps they don't disengage. Perhaps they wobble about together as conjoined bubbles sometimes do. I wonder if they can pop? As with our real-world bubbles, a meeting of more than two might make for some interesting variations. Perhaps it's a big bubble-bath out there!
That's all it is, a bit of visual play. It doesn't agree with our observations of the accelerating expansion in our current epoch.
Thinking of another challenge: if anyone can describe to a non-mathematician like me, how to visualise/analogise the square root of -1, do please share!
