Tributes poured on social media as scientists and celebrities hailed a man who had brought complex science to the masses with his best-seller “A Brief History of Time”.
The US space agency described Professor Hawking as an “ambassador of science”.
“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 the Space Station in 2014,” it tweeted.

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
