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 electron 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.
That’s not how that works. It’s not a DnD sphere of annihilation, it’s an infinitely dense point of matter.
