The actor, who won an Oscar for his portrayal of Prof Hawking in 2014 film The Theory Of Everything, said in a statement: "We have lost a truly handsome mind, an astonishing scientist and the funniest man I have ever had the pleasure to meet".
In "A Brief History of Time", Hawking "made some rather perceptive remarks to the effect that physics can not even in principle explain why there is an actually existing universe", Barr said.
Actress and neuroscientist Mayim Bialik, who met and worked with Prof Hawking when he appeared on USA sitcom The Big Bang Theory, tweeted: "As we near Pi day (3.14) I join the global community in mourning the loss of the greatest physicist of our era". "He, and not George Gamow, is the father of Big Bang", Hawking said.
Nothing has been finalised but his death is likely to be marked by "some combination of events and other form of memorial", - which will be organised between the family, the college and Cambridge University as a whole, she said.
In loving memory of Stephen Hawking.

Sadly, Drake revealed that he has pineapple on his pizza, which means that we must now exile him from humanity. Now, bear with me - I'm no Fortnite expert - but according to more reasoned observers he's not bad at the game.

With Tillerson Out, Trump's Bringing Foreign Policy Deeper Into the Dark Side
His attempts to reach out diplomatically to North Korea earned him a public scolding from Trump. But Tillerson wasn't just a thorn in Trump's side. "I'm concerned", he continued.
Hawking was a member of the Pontifical Academy of Sciences since 1986.
The actor who played Stephen Hawking in a film about the scientist's life has described him as the funniest man he ever met.
"It would not be much of a universe if it wasn't home to the people you love".
Meanwhile, from the worlds of science, technology and space, Nasa said Prof Hawking's theories "unlocked a universe of possibilities".
There are few scientists who reach as far into popular culture as Stephen Hawking did. He also proved that cosmological models, extrapolated backwards in time, give rise, under very general conditions, to a "Big Bang" or an initial singularity, "adds Mazzitelli, who is a CONICET researcher in the Group of Particles and Field Physics". The professor's first wife said she understood why Hawking might struggle to believe in God "because he had been [given] such a damning diagnosis". "Black holes ain't as black as they are painted", Hawking quipped. Along with the image, wrote: "You have to have a positive attitude and get the best out of the situation in which you find yourself", followed by Hawkings name. One day in February of 1992 (see note at bottom), I was walking with Gerry Brown, a nuclear theorist who also visited Caltech each year in the Spring, together with Hans Bethe, Brown's collaborator on the theory of binary neutron stars, along the lovely paths in Arcadia's Arboretum. As a matter of fact, Hawking's work has more impact than Einstein and Newton's as it is a guiding research in present and more years to come.
His theories on gravity and black holes were written up by Hawking for his best selling book released in 1988 - A Brief History of Time.
