Less than you might suppose. A micro black hole that the LHD could generate is a tiny tiny hole, and you can only cram a tiny amount of matter down it at once.
An extreme lower bound on the time such a black hole might take to grow large enough to destroy the Earth is on the order of 10,000 years. More likely it would take longer than the lifetime of the Earth.

- lliamander 5y agoBut can we safely dispose of the micro black hole (say, by launching it into space) and how long do we have before it becomes too big to deal with?
- PaulHoule 5y agoIt would make a good science fiction story. Somebody drops a black hole into the Earth which interacts very weakly with the Earth other than gravitationally so it is falling back and forth through the Earth every 90 minutes or so with the Earth rotating around it so it shows up at different spots. As the hole takes on mass the height it reaches will diminish and rotationally it will catch up with the Earth, but it takes a while. People rush to move a https://en.wikipedia.org/wiki/Very_large_floating_structure https://en.wikipedia.org/wiki/Very_large_floating_structure into place to catch it.
