In a video I watched, which I can't find now, Leonard Susskind briefly mentions something about scientists recently creating what seemed to be a black hole in a collider (not the LHC). He said that the scientists needed to use string theory and extra dimensions to make sense of it. Something like that. He didn't seem to want to jump the gun about it or give too much info, that perhaps it hadn't been confirmed or something like that. Can anyone point me in the right direction about this? I'd like to find out more about the experiment in question, and maybe figure out which video that was. Thanks.
