This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

There actually is a method that could be used to extract energy out of a black hole. Probably not something you'd build in a watch-sized device though.
it only seems to work for rotating black holes though?
Don't they all spin though? As in any matter falls in one way or another angular momentum is gained.
It is possible, but very unlikely. Maybe two bh merge that has exactly opposite angular momentum.
