Stephen Hawking, in full Stephen William Hawking, (born Janu, Oxford, Oxfordshire, England—died Ma, Cambridge, Cambridgeshire), English theoretical physicist whose
theory of exploding black holes drew upon both relativity theory and quantum mechanics. He also worked with space-time singularities.
What is Stephen Hawking's disease?
While in graduate school, at age 21, Dr. Hawking was diagnosed with
Amyotrophic Lateral Sclerosis (ALS), commonly referred to in the U.S. as Lou Gehrig's disease. As ALS progresses, the degeneration of motor neurons in the brain interfere with messages to muscles in the body.

Can information escape a black hole?
One of the leading researchers is Netta Engelhardt, a 32-year-old theoretical physicist at the Massachusetts Institute of Technology. She and her colleagues have completed a new calculation that corrects Hawking's 1974 formula; theirs indicates that information does, in fact,
escape black holes via their radiation.
How does Stephan Hawking talk?
How did Stephen Hawking talk? Hawking previously used his finger to control a computer and voice synthesizer. But once he lost use of his hands, he
started depending on twitching a cheek muscle to communicate. ... Whenever the cursor reached a word or phrase he wished to use, Hawking twitched his cheek muscle to select it.
Do ALS patients feel pain?
Although not generally associated with ALS,
pain has been reported to occur in nearly 70% of ALS patients at some time during the course of the disease [6–8]. Moreover, the frequency of pain seems to be directly proportional to disease progression [7].
