Time travel possible?
Via Boing Boing, The Boston Globe: Professor's time travel idea fires up the imagination. "Ronald Mallett, a physicist at the University of Connecticut, believes he knows how to build a time machine - an actual device that could send something or someone from the future to the past, or vice versa... He's not joking."
"If his idea pans out, won't there be a host of potential paradoxes, such as time travelers killing their parents and making it impossible for them to exist? No, he says, explaining that those travelers would continue to exist in a ''parallel universe.''"
