Have a thread.
Gonna wax physics.

So.
Here's what we know.
Matter has mass.
Mass is given to it by the Higgs mechanism.
The how of that, I'm not certain of.
Anyway, that mass creates gravity.
Gravity is a force that pulls spacetime in a direction (namely, towards the particle) ever so slightly.

You get a bunch of particles in a location and their combined gravity increases in strength.
The more tightly packed the mass is, the more gravity is present.
Which is why black holes are a thing.
You have the mass of a big star compressed into an area of, say, a few miles.

Now, here's the meat of my thought.
So, recall how every single space travel scifi movie talks about the paper wormhole thing.
You bend space and kinda poke a hole through it and you travel through those holes and boom you have a wormhole. Portals!

How do we do that?
The general idea is that you have two "black holes".
And you sort of create a tunnel of space between them.
See, the whole paper bending thing wouldn't really work in reality because space is 3D.
You try folding an inflated balloon. Not happening. Not easily.

So you have to get creative or find the 3D equivalent.
Also worth noting that one of those black holes is actually a white hole.
What's that?
Black hole succ.
White hole spit.
How?
Negative mass.
If positive mass drags space toward it, negative mass will push it away.

Gives us sort of a space bulge.
Versus regular mass giving us space depressions.
So you have one hole making us fall into a space pit.
The other is making us ride the volcanic eruption out.
Easy, right? Nah.
Cuz we don't know how to get negative mass.
The fuck would that be?

A thought for another time.
Also worth noting, not all black holes have to be death machines.
Natural ones are, cuz you have to get hella massive to naturally compress like that.
But what if we could turn something less massive into a black hole?
Say, a pyramid.

A pyramid-mass black hole would be tiny and have a Schwarzchild radius that's really tiny.
Like subatomically tiny.
More on the radius later.
Also worth noting that it wouldn't last very long (I think a year) and because of that tiny radius, it wouldn't do much damage. Too small.

So, to recap a little bit.
Mass density in a given area corresponds to the gravity of the area.
More density = more gravity.
So big mass in small space is (eventually) a black hole.

A mass has a Schwarzchild radius.
If the mass is compressed to that radius, you have an almost black hole. Light can touch base and escape just fine. Although nothing else will.
If that sphere of mass gets compressed even more, you end up with a gap known as the event horizon.

Now you have a black hole.
Stuff ends up there and doesn't come out (aside from Hawking radiation).
Now here's the fun part. If your black hole is small enough, it won't do much damage because it'll have too little surface area.

So let's say we have a black hole about four feet in radius. Size of a human. What's the strength of gravity?

Fucking too much.
Okay, we have an issue.
Our black hole is big enough to walk through if it were a portal, but it's not. Too strong. What do?

Here's an idea.
Alter the geometry.
I propose this. You have a ring of singularity.
Basically you've altered the shape of the black hole.
And now you can walk through it.
But wait, it can't support itself!
What do?
Negative mass!

You can have some negative mass, a negative singularity ring, perhaps, keeping the black hole ring stable enough to exist, and you can also walk through without getting destroyed.
Will that work? I dunno.
