He had a rare early-onset, slow-progressing form of amyotrophic lateral sclerosis (ALS) that gradually paralysed him for decades.
However, having been diagnosed early on, Hawking defied the odds and lived a highly successful and full life.
He was the author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. His scientific works include a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that black holes emit radiation.
We were on earth at the same time as Stephen Hawking.
That’s kind of a miraculous thing.
We breathed the same air as the man who demystified the stars.

History will record that Stephen Hawking used the last time he had remaining on this earth to fight for the thing Britain treasures most. Our NHS.

We’re deeply saddened to hear that Stephen Hawking has died. In 2015 Hawking attended the Film Awards and watched Eddie Redmayne win a BAFTA for portraying him in The Theory of Everything ❤️ pic.twitter.com/1egryy8xVG

His passing has left an intellectual vacuum in his wake. But it’s not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP 1942-2018. pic.twitter.com/nAanMySqkt

Remembering Stephen Hawking, a renowned physicist and ambassador of science. His theories unlocked a universe of possibilities that we & the world are exploring. May you keep flying like superman in microgravity, as you said to astronauts on @Space_Station in 2014 pic.twitter.com/FeR4fd2zZ5
