Even if you've won the Nobel prize and cultivated a lifetime of world-renowned advancements in the scientific community, you're just not somebody until you've appeared on 'The Big Bang Theory.'  That's right 'Bang'ers, after what seems like a lifetime of trying, 'The Big Bang Theory' has finally managed to make the theoretical reality, bringing in world-renowned physics robot professor Stephen Hawking!

The good professor will appear opposite Sheldon Cooper (Jim Parsons) in a scene filmed for the current season's 21st episode, to air on April 5.

Unlike the recently-announced casting news of 'Star Trek' and sci-fi icon Leonard Nimoy, Hawking will appear in person, much as he did for a 1993 episode of 'Star Trek: The Next Generation.'  Since then, Hawking's appearances in pop culture TV have largely been limited to voicover for series like 'The Simpsons' and 'Futurama.'  'The Big Bang Theory' had attempted to recruit Hawking a number of times in the past, but the professor's illnesses usually prevented it.

Hawking joins the ranks of other esteemed scientific and technological figures to appear on the CBS sitcom, including astrophysicist Dr. George Smoot, theoretical physicist Dr. Brian Greene, and Apple co-founder Steve Wozniak.  Hawking himself had previously been referenced on the show as well, as Wolowitz (Simon Helberg) once left a voice message on Sheldon's answering machine pretending to be the noble professor asking to discuss Sheldon's theories over donuts.

What say you, science guys and 'Big Bang Theory' fans?  Is Hawking's appearance bound to theoretical comedy gold, or an unwise use of the professor's time?  Someone's got to stop this crazy universe from expanding, as long as our best scientists spend their time on TV!
