World-renowned author/physicist Stephen Hawking kicked off the fun at THE BIG BANG THEORY Comic-Con panel on Friday, July 19, 2013, via a pre-recorded video segment shot in his Cambridge office. Hawking greeted Comic-Con fans and — in his own inimitable, self-deprecating way — cleared up any confusion about our universal origins by explaining the actual "Big Bang" theory in only 17 words! #WBSDCC
