So, I watched PBS Space Time video while thinking about ...
(tl;dw: gravity is an illusion caused by the earth accelerating outward in curved space time at 9.81 m/s^2, and a spontaneous vacuum collapse is a region of space expanding at near light-speed that has a lower energy than normal space, and is therefore the preferred state of the universe, regardless of the preferred state of life or matter)
And then I thought, "wait, wouldn't a black hole's event horizon also expand outward at the speed of light by this logic? Does that mean that all black holes, micro or supermassive, are actually vacuum metastability events?"
P.S. hi! P.P.S. I'm not high. P.P.P.S. I wish I had a normal thing to say, but alas my life is abnormal.

Normalcy is boring.

But if abnormallity is the norm for a person, wouldn't it still be boring?

Nope, because abnormality begets chaos.

Fair enough.
Now, should I change majors to theoretical physics and attempt to prove that these are the same thing only to be held back by the lack of a quantum theory of gravity and/or being too sensical to be true? According to the Internet, no one else has made this connection.

Go for it. I smell a graduate thesis in the making.

Aren't gravity and the force created by the Earth's rotation opposite in nature? Gravity is a centripetal force while the force of the Earth's rotation would be centrifugal...

Another thing to add.
According to , white holes have gravitational fields, yet an object would never reach the white hole. So an object falling toward a white hole will gain speed, then slow down, then freeze (temporally, not thermodynamicly) as it reaches the white hole's "event horizon."
This looks suspiciously like the description of events of an object falling into a black hole from the prospective of an outside observer. Could white and black holes really be the same thing?
After you digest that, consider that a white hole is explicitly considered to be a black hole going backwards in time. Could one conclude that time can only go in one direction even in theory?

The math allows both directions of timeflow. We only precieve it as going in one direction.

Speaking of memory, this guy's story fascinates me: https://en.wikipedia.org/wiki/Henry_MolaisonAs for Clive... he knows of time passing, and he knows he is getting older. (Not all of his encoded memory is gone.) As for a theoretical case of a person with complete amnesia, it is hard to really guess how they experience time. If it even is a "thing" to them. Indeed, it would be difficult to even function, without procedural or past encoded memories.

Alright, one more idea for my sci-fi daydream journal.
Consider the Alcubierre drive (sorry for not posting a link for this). In theory, this drive creates a "warp bubble" that travels arbitrarily faster than light and requires negative energy on the outside of the bubble to function, presenting two problems:
1.) How do you produce enough negative energy? 2.) How to you keep the negative energy conditions needed outside of the warp bubble following the warp bubble?
We could call the first problem a simple matter of engineering, since we can produce negative pressure with the Casimir effect already, but the second problem would need drastic solutions like laying down and maintaining the conditions required to maintain the warp field, like a space highway.
From my armchair, I maintain that these problems are actually insurmountable, as taken together they require that we basically build a tunnel from here to any star we want to go. So why don't we think on a smaller scale?
Like super-reletivistic telephone cables?
If we could send a warp bubble down a cable, we could increase transmission speed to the point where it could very well break causality. There would still be engineering hurdles to overcome, but not any of the "crochet ladder between the Earth and Andromeda" kind.

The Alcubierre drive has been solved. (As a Trekkie, I am VERY invested in the tech. Lol.) All it needs is "exotic matter", which we have yet to discover/create.
Then, we can make warp drives.
That said, are working on ways to make it sane.

I know, I'm just acting under the assumption that the exotic matter can't be made and at best exists somewhere inaccessible to us.

They just turned on an actual fusion generator yesterday. Never say never.
