Stephen Hawking is a noted theoretical physicist, cosmologist, author and professor. His research into general relativity and quantum gravity achieved popularity with his book, A Brief History of Time.
Stephen Hawking is a hero of Sheldon, Leonard, Rajesh, and Howard. Howard and Raj were overjoyed to show Sheldon and Leonard a Stephen Hawking lecture from MIT in 1974, before “he became a creepy computer voice,” according to Howard, who reveals as much with his characteristic hand-to-mouth impression. (1×01: “Pilot”) Meanwhile, Leonard anxiously shared with the guys that David Underhill did this hysterical impersonationof Stephen Hawking having phone sex with a robotic monotone: “What are you wearing?” (2×11: “The Bath Item Gift Hypothesis”) Also, Raj has stated the guys left that fake message from Stephen Hawking on Sheldon’s voice mail, with Howard’s impression: “I wish to discuss your theories of black holes. Meet me at the Randy’s Donut by the airport at 2:00 a.m.” (4×21: “The Agreement Dissection”) Sheldon particularly worships Stephen Hawking. In fact, Sheldon dressed up as him for Halloween when he was six years old, thinks he is perhaps his only intellectual equal, and was willing to undergo a series of grueling tasks beyond comparison to the Twelve Labors of Hercules in order to meet him.
