Everything about quantum mechanics (which deals with theoretical properties of the subatomic world) is mind-blowing as are many things about astrophysics which is why I love the subjects so much - it can really screw your mind up trying to get your head around it.
Indeed! The very fact that all creation stems from one 'Big Bang' screws my mind up big time. I've always wondered how such a massive explosion could occur if there was nowhere for it to happen.
Cern says:
"While an explosion of a man-made bomb expands through air, the Big Bang did not expand through anything. That's because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe."
So this 'event' was supposed to have taken place 13.7 billion years ago - the beginning of time.
"The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe."
But when did this tiny dense point (full of potential energy) originate if time had not yet begun? And where did this explosion happen if there was no space?
And an even bigger question. How can the brains of beings (who have supposedly been created as a by-product of all this expansion and evolution) possibly begin to explain the creation of everything that created them?
Aaaaargh!!!

I find it all absolutely fascinating, but extremely confusing and mind boggling. I’m not a scientist, but enjoy trying to get my head around information about the planets, stars, galaxies, black holes, dark matter, the universe, etc, etc. There’s so very much out there that we just don’t know about or know very little about. The shear distances of places from Earth and the sizes of the black holes are what blow my mind.
Perhaps space isn't almost a vacuum at all. Maybe it's crammed full of things that we can't sense, in the same way that there are things you can't see in the plant and animal worlds without ultra violet light

You are absolutely right! There is no such thing as 'empty' space. I've read books on what 'space' is made of (Quantum Loop Gravity [maybe] - Carlo Rovelli) which screws my brain up even more. Even a total vacuum is crammed with quantum foam with particles popping into and out of existence, and electromagnetic fields still propagate through it

I'm working on the basis, probably naive, that once the most dense and avaricious black hole has swallowed everything else up it will be so utterly dense in there it all just has to go bang and start all over again.
All that energy has to go somewhere after all.

But the event 13.7 b years ago was the LAST Big bang
Roger Penrose talks about his theory-

Of course it still begs the question, when was the FIRST Big Bang
You can see how it messes with your mind!!
