Neil deGrasse Tyson

If Neil deGrasse Tyson says that teddy bears can walk and talk and make crude jokes, then it must be true!

Above we have Neil deGrasse Tyson's address at the 28th National Space Symposium. If you have a free hour in your day I highly recommend watching the whole thing, as deGrasse Tyson addresses everything from Newt Gingrich's proposed moon base to the way space travel is a pervasive force in our everyday culture.
