Stephen Hawking, who sought to explain some of the most complicated questions of life while working under the shadow of a likely premature death, has died at 76, Reuters has reported.
He died peacefully at his home in the British university city of Cambridge in the early hours of Wednesday.
â€œWe are deeply saddened that our beloved father passed away today,â€ his children Lucy, Robert and Tim said in a statement.
Hawkingâ€™s formidable mind probed the very limits of human understanding both in the vastness of space and in the bizarre sub-molecular world of quantum theory, which he said could predict what happens at the beginning and end of time.
His work ranged from the origins of the universe, through the tantalising prospect of time travel to the mysteries of spaceâ€™s all-consuming black holes.
â€œHe was a great scientist and an extraordinary man whose work and legacy will live on for many years,â€ his family said. â€œHis courage and persistence with his brilliance and humor inspired people across the world.â€
