Comment on That explains a lot

Then somebody drops it and it just falls down to the planet’s core and eats our fucking world.
Ok, so even if it “falls down”, it will probably evaporate way before it even reaches the center. Even if it doesn’t, it will be take A VERY LONG TIME for it to get big enough to eat the planet out or whatever.
It is very VERY difficult to make something fall inside a black hole. Mostly, stuff just zooms right past it at incredible speeds.
The earth would be consumed by the sun way before it gets consumed by a black hole.
You’re talking at scales where the incoming mass has a lot of velocity already. In a stationary frame of reference, the matter would more than likely fall directly in since there isn’t an appreciable amount of rotational momentum involved like there is at stellar sizes.
That’s not really how black holes work. They evaporate really quickly when they’re small enough. And if they’re small, they don’t have much gravity either.
We'd have a quasi-planet.
That’s not how that works. It’s not a DnD sphere of annihilation, it’s an infinitely dense point of matter.
That shrinks in a vacuum but grows as other matter gets too close. Matter such as “the earth”. Explain how we’re not fucked if it escapes from its magnetic vacuum suspension because Kevin accidently drops it.
There is a surprising amount of empty space between atoms, and even inside atoms between the eleftron orbitals and the nucleus. Small black holes are so dense they mostly fall through this empty between-atom space and don’t actually hit anything. Even in a matter-rich environment like inside the Earth, you’d need a black hole with more than half the mass of the moon to be large enough to eat matter faster than it loses matter to Hawking radiation.

The way we are going, its for the best

I’m not saying we shouldn’t do it.
