Studying Black Holes in the Lab 9
Alien54 writes: "As seen in this UPI Report, Lab-created "dumb holes" - the acoustic, or sound wave analogs of black holes - may provide important experimental evidence for quantum gravity, a theory that unifies atomic and gravitational forces. Dumb holes arise when fluids flowing faster than the speed of sound form regions that trap sound waves. They too have a surface of no return -- the "acoustic horizon". While black holes remain interstellar objects, researchers can create dumb holes (Sonic Black Holes) in a laboratory. Dumb holes that trap sound waves may yield experimental evidence used to understand quantum gravity because these acoustic black holes exhibit all the characteristics - paradoxes included - of their light-wave brethren. well not quite all. For one thing, sonic black holes do not involve gravity and distortions of space and time."

So how does this help us get experimental evidence of quantum gravity?!

I can imagine that if a "sound hole" opened up on another planet, aliens would get a bit of a shock when from close behind them invisibly comes the sound... "hello? testing, testing. hey cool, its absorbing my voice...".

Maybe it was actually a dumb hole.
