Stephen Hawking was a world-renowned British theoretical physicist, known for his contributions to the fields of cosmology, general relativity and quantum gravity, especially in the context of black holes. In the 1960s and 1970s, he worked on ground-breaking theorems regarding singularities within the framework of general relativity, and made the theoretical prediction that black holes should emit radiation (known today as Hawking radiation).
He has also published several works of popular science in which he discusses his own theories and cosmology in general, including the runaway bestseller “A Brief History of Time”, and has come to be thought of as one of the greatest minds in physics since Albert Einstein. In his own words: “My goal is simple. It is complete understanding of the universe, why it is as it is and why it exists at all”.
In October 1962, Stephen arrived at the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge to do research in cosmology, there being no-one working in that area in Oxford at the time. After gaining his PhD (1965) with his thesis titled ‘Properties of Expanding Universes’, he became, first, a research fellow (1965) then Fellow for Distinction in Science (1969) at Gonville & Caius College.
In 1966 he won the Adams Prize for his essay ‘Singularities and the Geometry of Space-time’. Stephen moved to the Institute of Astronomy (1968), later moving back to DAMTP (1973), employed as a research assistant, and published his first academic book, The Large Scale Structure of Space-Time, with George Ellis. During the next few years, Stephen was elected a Fellow of the Royal Society (1974) and Sherman Fairchild Distinguished Scholar at the California Institute of Technology (1974).
He became a Reader in Gravitational Physics at DAMTP (1975), progressing to Professor of Gravitational Physics (1977). He then held the position of Lucasian Professor of Mathematics (1979-2009). Stephen was currently the Dennis Stanton Avery and Sally Tsui Wong-Avery Director of Research at DAMTP. Professor Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein’s general theory of relativity implied space and time would have a beginning in the Big Bang and an end in black holes (1970).
These results indicated that it was necessary to unify general relativity with quantum theory, the other great scientific development of the first half of the 20th century. One consequence of such a unification that he discovered was that black holes should not be completely black, but rather should emit ‘Hawking’ radiation and eventually evaporate and disappear (1974).
Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science. Recently Stephen has been working with colleagues on a possible resolution to the black hole information paradox, where debate centers around the conservation of information.
His many publications include The Large Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravitation, with W Israel. Among the popular books Stephen Hawking has published are his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays, The Universe in a Nutshell, The Grand Design and My Brief History.
In 1963 Stephen was diagnosed with ALS, a form of Motor Neuron Disease, shortly after his 21st birthday. In spite of being wheelchair-bound and dependent on a computerized voice system for communication Stephen continues to combine family life (he has three children and three grandchildren) with his research into theoretical physics, in addition to an extensive program of travel and public lectures. He still hopes to make it into space one day.
He passed away yesterday morning and the news saddened everyone. Even Bollywood star tweet on the demise.
Here are the list of tweets to the legend:-
RIP Stephen Hawking. A major loss to the scientific community & to the millions he inspired through his work and life. Condolences to the family.

RIP Stephen hawking. He had once said he’s not afraid of death but he is no hurry to die because he has so much left to do.
True genius who’s been an epitome of strength and courage 🙏🏽 #StephenHawking

“We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.” — #StephenHawking

Oh wow. This hurts. It really hurts. What a guy, what a story, what a life, what a humongous contribution to humanity, to our knowledge and understanding of the Universe. #StephenHawking , thank you for sharing your genius with us all.
