Good way to make soundproof walls.


But if they have too many clumped together, they'll merge and get more powerful.


So, making a black hole is worthless, at the moment. We may be able to find an application later on(gun silencers, maybe?)
i liek turtelz xd
Just to inject a wee bit of science, or what little I can contribute:

A black whole is a bit of mass that is so dense that light cannot escape, as you all know. However, that doesn't mean that it needs to be some huge blubbering object in deep space... I could have a black hole in my coffee cup, for instance. But it's just an incredibly dense thing-It doesn't need to have a lot of mass..Just a lot of density. So, when people collide atoms, first off..The black holes made, if any, could only have as much mass as the atom it was apart of..cause black holes are just incredibly dense, not heavy. Remember how far away the electron shell was from the nucleus? The particles in an atom are SMALL. So, the black holes resulting from the collision of said atoms is even smaller, because they are made from parts of particles. Don't you get it? The black holes are a fraction of the size of an atom[A very large fraction]. The event horizon is where the acceleration of gravity is greater than the speed of light, a constant.

That being said, this isn't a gravitational black hole...On one hand, sound isn't an electromagnetic wave, so it needs a medium to travel through. Atoms normally vibrate. At absolute zero, they don't vibrate. The speed of sound also drops as temperature drops...So... Not sure what to make of it. It definately won't prove or disprove Hawking radiation, though, that's for sure.

Lol, interesting but not practical :P
How about simple noise cancellation technology that's used in aviation headsets today?

A REAL black hole might be good for slingshotting spacecraft though.

Oh look, someone who has done research. You could also detect its presence through the detection of hawking radiation emited by the distorted matter etc, provided it exists (the radiation that is).

Here's the kicker- supermassive black holes can have a low density.

Supermassive blackholes are suggested to make up for the "missing mass" in every galaxy (including our own). The M-Sigma relation suggests relation between the formation of a galaxy and a supermassive black hole

I'm not following - the 'here's the kicker' part. How is that relevant to my post?
Thanks.

The funny thing is when I was watching the discovery channel last night about 3 ~ 4 a.m. There was a show about black holes ;)
You made reference to the infinite density at the singularity.

Incorrect.
For it to be a black hole, NO light escapes.

You can theoretically have black holes that are "brighter" than others.
Also, when the push force of the emited radiation equals the pullforce of the gravity... well you know.

In fact, the black hole in the M87 galaxy is brighter than the galaxy itself
it wasn't a black hole, but it acted like a black hole on sound waves.
