Any blackhole created in the lab would evaporate via Hawking Radiation in an extremely short timespan, and would have such a fantasically small event horizon that a proton would be as big compared to it as the sun is to a small rock from your backyard.

You'd have to create a blackhole from a Mt. Everest worth of mass before there was any potential that it could grow faster than it would evaporate.

There is no danger here.

FrancoFile: Ambitwistor: FrancoFile: zero-point fluctuations around a very small black hole could provide nonpolluting energy

You're not going to get more energy out of a black hole than you put into creating it.  The laws of thermodynamics win again.

I know that.
But the micro black hole is portable.  Create the black hole in a fixed facility, drop it in a container, and put the container on a boat/plane/whatever.


I think the point is that if black holes evaporate by giving off Hawking Radiation, and you can create a situation whete you have a very tiny black hole and you feed it matter at the same rate it boils off, you can actually get very efficient matter to energy conversion.

/ Very speculative, of course.
// But as the article mentions, it's not believed to be remotely feasible.

Actually they did. It's under the passenger seat so please don't drop my sunglasses.

Slaxl: Since black holes emit radiation, a tiny black hole should only last a very short time, not long enough to do any serious harm, so what's the problem? It's not like it'd feed, grow, and start swallowing the Earth.

1) Black holes will have the same mass as the material that was collapsed to create them.

2) Gravitation follows the inverse square law.

3) The reason that regular black holes are difficult to escape is because the mass of the sun (really big) is collapsed to a singularity (really small). So that all of the gravitational strength is concentrated on a tiny little point.

Therefore, if you want to create a black hole that's going to cause trouble here on earth, you need to start with a big mass ... like your mom.

Quantum Apostrophe: Also, we would not be able to create a black hole that is large enough to withstand being ripped a part by the Earth's larger gravity.

???????


It's more that the black hole would evaporate, not get ripped apart by Earth's gravity.

We do what we must, because we can.

We're a type 13 planet in it's end stages so it will happen any day now.
