He's a pompous shit bag that desperately wants to be Carl Sagan or something. He's been proven wrong many times and is just a hype man for physics lite. I've seen him speak before and lemme tell ya starting off your talk on PHYSICS with political turn out of the area you're speaking in is a great way to alienate your audience. He's at best a salesman to get kids into physics. At worst he's a female groping nigger that only has any accolades due to being an inner city black youth that made it. Fuck him.
