We've always known astrophysicists define the functional parameters for our universe.

They're also the very definition of hotness, as is evidenced by any peer reviewed movie. (Top Gun, Thor, The Day The Earth Stood Still).
Who doesn't aspire to be a 'man/woman of science'? Most prefer high speed vehicles, substance abuse and loud hip hop. Just don't orbit too close, they're a collapsing singularity of thrill-seeking danger.

[Technically, Dr. Hawking is a theoretical physicist. But his work has so many direct applications to cosmology (and he's such a badass) we had to include him.]
