Fast-Moving Black Hole

Posted by michael on from the vacuum-cleaner dept.

otisaardvark writes "New Scientist story about a very fast moving Black Hole in our very own Galaxy. Seems it was formed from a supernova explosion. I wish stars like this could have a more exciting name than GRO J1655-40 though. More at the BBC."

    Black holes the size of protons would evapourate in seconds, due to the hawking radiation, and somehow I don't think you want to get too close to a large one. I'd love to see someone try, though, that would be a great stunt to see on Jackass.

    Supernova lose about 10% of the mass of the final neutron_star/BH. In this case, final mass is 7 solar mass, so the energy released is 0.7 * solar_mass * c^2 which is about 10^54 ergs.
