brotundspiele@sh.itjust.works 3 weeks agoThere 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.
If the well, event horrizon expands when a blackhole takes more mass, why can’t we just figure out how much volume it is compressed into by measuring the event horrizon increase?
We know the matter that goes in is a certain size. Maybe we can deduce the total size it is compressed to? And the size the blackhole gains.
It’s impossible to know based on the current understanding of physics. A black hole is formed when the inward gravitational force exceeds the neutron degeneracy pressure of a sufficiently massive object, which is what keeps neutrons from occupying the same space (not really, it’s complicated). Beyond that, only conjecture exists with no evidence.

it only seems to work for rotating black holes though?
brotundspiele@sh.itjust.works 3 weeks ago
Yeah, that’s why you have to wind up your watch every now and then. To spin up its internal black hole again.

just drink more it’ll start spinning soon enough

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.
