The British physicist died, according to a statement from his three children.

Stephen Hawking died at the age of 76 years old, according to his family. The globally-recognized theoretical physicist revolutionized science's understanding of black holes and relativity. 

In more recent years, Hawking had been a proponent of expansive space travel and had been very open with his thoughts on artificial intelligence. 

His children Lucy, Robert and Tim made this statement to the press: "We are deeply saddened that our beloved father passed away today."He was a great scientist and an extraordinary man whose work and legacy will live on for many years."

Hawking wrote one of the most influential and popular science books, A Brief History of Time, which sold more than 10 million copies. His life was featured in award-winning biopic The Theory of Everything

Hawking suffered motor neurone disease which was discovered just before marrying his first wife Jane. Doctors gave him just two or three years to live in 1964. However, given the slow progression of the disease, Hawking was able to have his three children, and his disease never seemed to impair his mind. Hawking continued to lecture and write commentary on scientific discoveries despite being almost completely paralyzed. 

"He once said, 'It would not be much of a universe if it wasn't home to the people you love.' We will miss him forever," his children said.

Hawking also left a wide mark on the scientific community at large. Fellow astrophysicist Neil deGrasse Tyson said that Hawking's passing "left an intellectual vacuum in his wake."
