Lab-Made Fireball May Be a Black Hole
MoogMan writes "BBC News reports that a lab fireball may be a black hole.
From the article: "A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said. The Brown researcher thinks the particles are disappearing into the fireball's core and reappearing as thermal radiation, just as matter falls into a black hole and comes out as "Hawking" radiation." More information available from the NewScientist article (subscription required)."

The black hole would not behave as a pendulum for long. As it takes in new matter the system must conserve momentum. So if it fell half way to the center of the earth and then gained some mass, it would lose velocity, and hence not have enough speed to make it back to the surface on the next oscillation. The resulting black hole floating around the earths core would be very interesting. Just think of all the earthquakes we'd have as the planet slowly shrank - or not so slowly...
I once heard a remark at some long forgotten source of unknown credibility that stated the amount you would have to jam together to consume earth before it radiated itself away in Hawking Radiation was about the size of Mount Everest. Take this with a couple kilograms of salt, mind you, as I don't recall the source.

I think professors should be called in to teach you about black holes.
:) Aren't there a few different theories about black holes? Seems to me that something that warps space/time so drastically that it causes standard equations to get messed up is not something to tread on lightly.
:) I am not a professor, black hole expert, relativity expert, physics expert, or yadda yadda. This was just my opinion based on my poor memory about black hole research I've read. If someone has more information on this, I'd be interested in hearing it.
Which one?
Now, for my disclaimer so I don't get flamed too bad if I'm out of touch with research here.
