World-famous theoretical physicist, cosmologist, astronomer and mathematician Stephen William Hawking passed away at the age of 76.

 He was born on Jan. 8, 1942, in Oxford, England.

 Notably here, World-renowned physicist Stephen Hawking answered questions with the help of a voice synthesizer during a news conference at the Tata Institute of Fundamental Research (TIFR) in Bombay, in 2001.

Three years after when he was diagnosed amyotrophic lateral sclerosis (ALS), still Hawking was able to accomplish his doctoral work in theoretical physics at Cambridge University and he successfully submitted a thesis on black holes in 1966.

His most acclaimed book, “A Brief History of Time: From the Big Bang to Black Holes,” was published in 1988.

In 2004, Hawking inverted his original 1966 theory that black holes swallow everything in their path forever and announced that black holes never hold up space travel to other universes.

  Hawking survived with the fatal disease for over 50 years.

The disease ultimately left him paralyzed and completely dependent on others and/or technology for everything: bathing, dressing, eating, mobility and talking.  Worth mentioning here He was able to move only a few fingers on one hand.

To have a word, Hawking used a keyboard-operated electronic speech synthesizer adapted to his wheelchair.
