Today we lost Professor Stephen Hawking, he made science cool for the masses while being a great theoretical physicist. Despite being afflicted with ALS, he persevered and made an impact on humanity, his contribution to the sciences will be remembered for generations to come.

Hawking first earned prominence for his theoretical work on black holes. Disproving the belief that black holes are so dense that nothing could escape their gravitational pull, he showed that black holes leak a tiny bit of light and other types of radiation, now known as “Hawking radiation.”

“It came as a complete surprise,” said Gary Horowitz, a theoretical physicist at the University of California, Santa Barbara. “It really was quite revolutionary.”

Horowitz said the find helped move scientists one step closer to cracking the unified theory.

Hawking’s other major scientific contribution was to cosmology, the study of the universe’s origin and evolution. Working with Jim Hartle of the University of California, Santa Barbara, Hawking proposed in 1983 that space and time might have no beginning and no end. “Asking what happens before the Big Bang is like asking for a point one mile north of the North Pole,” he said.

I enjoyed his books and he will be sorely missed by many.
