See What a Black Hole Would Do to Earth with Online ‘Collision Calculator’
Have you ever wondered what would happen if Earth got gobbled up by a black hole (apart from everybody dying, of course)? Now you can find out, thanks to the online Black Hole Collision Calculator.

Interesting. I wonder what’s the least massive black hole out there.
The calculator allows you to work with black holes as small as 1kg.

Nice. What does it say for 1 kg black holes?
Primordial black holes may be smaller than that. Set a sufficiently small black hole on a collision course with Earth and it will pass right through the Earth without interacting with anything.
With a slightly larger black hole than that it settles down into the middle of the Earth and then grows so slowly that we wouldn’t be aware of it.
A larger black hole than that and the Earth will shrink measurably.

Sorry folks, I don’t trust the calculator for small black holes. I can’t get an initial radius other than exactly zero, even when that radius is measured in nanometres. And if the radius is that much smaller than 1 nm then its final mass will be its in initial mass, not 0.97 earth masses. Because for small black hole’s quantum effects mean that it flies through the open space between the nucleus and the electron without gobbling up anything other than the odd electron.
The smallest mass of black hole you should trust this calculator for is about 600 trillion metric tons.

600,000,000,000 tonnes you say? That was my working. Jolly good.
