And this is why you should not skip your physics classes.

Thought we had an out.. Nope we got to tackle fascism and climate change the hard way

Indeed, any black hole with a mass greater than about 0.75% of the Earth's mass is colder than the cosmic background, and thus its mass increases for now. As the universe expands and cools, however, eventually the black hole may begin to lose mass-energy through Hawking radiation.

Size isn't actually the main factor, mass is.

A teaspoon of what neutron stars are made of weighs as much as Mt. Everest.

Its the mass thats important, and apparently the threshold for an actually stable black hole is 0.75% the mass of Earth, 4.48 x 10²² kg .... or, roughly 2/3 the mass of the Moon.

(The Moon's mass is roughly 1/81th that of Earth's. It ks far, far less dense.)

So... basically 0 chance in our natural life times we'll figure out how to convert the Moon into a blackhole, lol.

EDIT:

There... could theoretically be a wandering black hole of aporoximately that mass... but even if it entered our solar system, chances are it would just get thrown out, deflected by Jupiter and the Sun, and it would only maybe eat some ice in the Kuiper belt, dust and maybe very small asteroids in the asteroid belt if it somehow made it past Jupiter.

Black holes don't have infinite gravitational vaccuum power that extends infinitely, because they do not have infinite mass.

if they did, the occurence of one would instantly eat the entire universe at the speed of gravity, which is the speed of light.

They have as much gravity as their mass says they should, and they obey the same orbital dynamics as every other massive celestial body.

I keep hearing commericals for them advertising to kill clover. Always annoys me. If clover grows in your yard, your yard likely needs the nutrients (nitrogen likely). Also, it helps bee populations, which helps well... Life.

Clover was never a weed until weed killer came around out and killed it with everything else in the grass. So they started an ad campaign that told people it was a weed and convinced people that white flowers in your yard look bad.

So now everytime I hear an advertisement that mentions killing clover I remind myself not to buy products by the brand who says it. Also, clover honey is delicious.

No, of course not. The accident eats all the light I'd need for that.

The way we are going, its for the best

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.

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.

We kinda don't know for sure though. The tinier the black hole gets, the more it enters into the realm of quantum mechanics. We have no clue how quantum gravity works, so ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
