Celebrities, public figures, and scientists from around the world have begun sending tributes to physicist Stephen Hawking, who died at the age of 76 early Wednesday morning.
American astrophysicist and Twitter celebrity Neil deGrasse Tyson tweeted a photo of himself and Hawking, saying that his passing has “left an intellectual vacuum in his wake.”
His passing has left an intellectual vacuum in his wake. But it’s not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP 1942-2018. pic.twitter.com/nAanMySqkt

In 1999, the Nobel prize-winning physicist appeared on an episode of “The Simpsons,” and appeared on the show three more times in following years.
Actor and Home Alone star Macaulay Culkin said the late physicist was “both a genius and my favorite Simpsons character.”
I just heard about Stephen Hawking’s passing. He was both a genius and my favorite Simpsons character. We’ll miss you, buddy.

Astronomer and popular science blogger Phil Plait highlighted Hawking’s scientific breakthroughs in a series of tweets.
Plait described how Hawking discovered how “the most powerful objects in the Universe” black holes “eventually dissolve,” and how Hawking lived for another 55 years despite his ALS diagnosis.
“He was the definition of mind over matter,” Plait said.
2) He had ALS, and when diagnosed he was given two years to live. He lived another 55.
He was the definition of mind over matter.

Theoretical Physicist and professor Matthew Buckley said Hawking’s genius extended far beyond his fame.
“Hawking was a great scientist. The world might not have known him had he never suffered from his illness, but they should have,” Buckley tweeted, before highlighting Hawking’s incredible work on black holes.
Hawking was a great scientist. The world might not have known of him had he never suffered from his illness, but they should have.
Just wanted to talk a bit about his work.
