Sheldon Cooper is about to meet his idol. We've already posted news on the cameo by renowned cosmologist and physicist Stephen Hawking to guest star on The Big Bang Theory on April 5. CBS revealed the plot on Friday, saying Howard Wolowitz will get a chance to work with Hawking, and Sheldon "is willing to do anything to meet his hero.”

“When people would ask us who a ‘dream guest star’ for the show would be, we would always joke and say Stephen Hawking — knowing that it was a long shot of astronomical proportions,” executive producer Bill Prady said in a statement about the show. “In fact, we’re not exactly sure how we got him. It’s the kind of mystery that could only be understood by, say, a Stephen Hawking.”

This won’t be the first real-life techie guest: In 2010 Apple’s Steve Wozniak had a cameo on the show. He interacted with a virtual Sheldon: watch it here.
