. >> it's interesting because post-doc at the time, we did some calculations.turns out that the l.a.c. doesn't even... even in those scenario it is l.h.c. can't make black holes. >> so anybody who's worried about a black hole being created swallowing up the earth... >> that goes beyond that. even if we could make black holes. but they're not going to swallow up the earth and the reason is that there's not property of black holes which is that they decay. they don't last forever. small black holes-- the only ones you can make are small because you don't have enormous energy, they're small. so they would decay. >> rose: i read the l.. will. willh.c. will take physics into the time where the current reigning theories don't apply. does that make sense in >> it depends what you mean by that. in the sents that basic laws of physics, quantum mechanics, those should still apply. >> right. >> but the way they're put together could be different. it could be, for example, there could even be new forces that we discovered there could be new particle wes discover so our law
