1) Phil Plait
2) It was about astriods and how we can avoid them hitting our planet. We now have a 1-2 ton craft that is able to very slowly change the direction of an astroid so it will miss our planet if we ever have a threat of one coming towards us.
3) This talk did change the way I think because I never really thought about our planet being in danger of something coming down and crashing into it like what happened to the dinosaurs. I'm relieved to hear that we have ways of protecting us from them.
