Black Hole in a Lab

This is rather cool. Using a charged carbon nanotube an atomic 'black hole' can be simulated. An atom spirals toward the tube until an electron tunnels into the tube. At that point the resultant ion is repelled away. In a real black hole a mass is accelerated as it orbits closer and closer to the event horizon. Eventually tidal forces causes it to disintegrate and a portion crosses the horizon. The remaining portion has enough velocity to escape. As black holes accumulate matter they also radiate much of it away.
