This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions like fire or explosions are very inefficient. Nuclear fission and nuclear fusion are better, but not amazing on an absolute scale. Non-rotating black holes (Schwarzschild) and rotating (Kerr) are by far the most efficient, due to their accretion disks and very small radius of their innermost stable circular orbits.

@cbarnes2160 Год назад

With a small enough black hole, you can convert 100% of the infalling mass to energy. Small ones are "hot" and have significant Hawking radiation. So you get one that's the right size to produce the power you want and then throw in mass periodically to keep it from getting smaller. If you stop feeding it, it shrinks, gets hotter and radiates faster and eventually blows up. But keeping it in balance is pretty easy if you are talking power needs along the lines of Norway or the world. Trickier if you want really gigantic power production from a smaller black hole.

There's an even better solution to this with rotating black holes. You can directly harvest the rotational energy of the black hole through superradiance of lasers. Surround it in a reflective surface - or more likely arrange wave guides in specific patterns, and superradiant scattering will dump huge amounts of energy into the laser drawn from the rotational energy of the black hole

P.S. If one is to use the percentage’s perspective (i.e., in the Nuclear Reaction’s section, 150 cats were supposedly needed (which is 100/0.7 = 142.9 cats)), the Chemical Reaction’s section shall then be needing a hundred billion, also not ten billion, cats.

I had no idea the event horizon would be further in in the spinning black hole. I thought the size depended on mass only and had wondered if it possibly was because space couldn't hold more information in that volume.

Hey, at least Schrodinger proposed putting just a vial of poison in his box to put the cat in a superposition of dead and alive. Einstein suggested a stick of dynamite. He then asked whether you really needed to open the box to learn whether the cat was alive or dead.

@fusiontricycle6605 6 лет назад

Questn, actually, as a macroscopic object, we are 99% energy and 1% matter. The protons and neutrons in our atoms weigh more than the sum of their parts (being the quarks inside them). The quarks alone account for 1% of the mass of the hadron and the rest is energy coming from the kinetic energy of the quarks and the strong force interactions binding them together.

@mediawolf1 10 месяцев назад

The object I threw into the black hole is crashing into stuff as it orbits / spirals in... but the stuff around the black hole is also necessarily orbiting / spiraling in, too. So the crashing doesn't have as much oomph. It's not like my object is crashing into stationary stuff. I could throw it against the tide of the accretion disk-then there'd be more violent crashing-but that goes against the thing he was saying about rotating black holes.

Time to update this great presentation: In Sept, 2020 LIGO reported a merger of two BHs of 85 and 66 solar masses to form a BH of 142 solar masses, radiating 9 solar masses! of gravitational wave energy, so the total BH mass was dramatically reduced (and not by Hawking radiation). What is the mechanism? Where was this mass/energy relative to the EH before merger? I can't find discussions of this anywhere, not in scientific papers, internet presentations or RU-vid. Thanks.
