Later in his career, he ruffled academic feathers with bizarre statements about extraterrestrials, time travel, and the creation of humans through genetic engineering.
But it still gives a sense of the puckish wit and unquestionable brilliance of a truly remarkable human being. It's the origin of this quotation.
The US Centers for Disease Control and Prevention estimates that 20,000 to 30,000 people have ALS in the United States, with about 5,000 new cases diagnosed every year.
"Things can get out of a black hole both on the outside and possibly to another universe".
British astronaut Tim Peake said the professor had "inspired generations to look beyond our own blue planet and expand our understanding of the universe". He beat the predictions. He said Hawking had been an inspiration to people with the disease for many years.
"Stephen's life was heroic, in so many ways", said Neil Turok, director of the institute and a friend of Hawking's who worked with him at Cambridge University. Hawking held his ground, and the howls of derision were quickly replaced by approbation.
His international reach was demonstrated in China, where news of his death generated nearly half a billion clicks as fans bade farewell on social media platform Weibo to a "giant star". A cursor automatically scans across this keyboard by row or by column.

Paralysis gradually sets in and causes respiratory failure, which most often leads to death within 2 to 5 years (depending on the form of the disease).
"More than any other scientist in recent history, his ability to engage people in the process of scientific discovery through his books, lectures and television programmes has opened countless inquisitive minds to a universe full of possibilities". "They all know who he is".
"The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge". Hawking, he added, "really is at the extreme end of the scale when it comes to survival".
Fellow actor Benedict Cumberbatch, who also played Prof Hawking on screen, said: 'He virtually created the publishing genre of popular science. Aside from the aforementioned movies, his influential bestseller A Brief History of Time was adapted for the big screen by peerless American documentarian Errol Morris in 1991.
