NASA’s tweet paying tribute to Stephen Hawking sums up how we’re all feeling

The physicist died peacefully in his home

Celebrated theoretical physicist and cosmologist Stephen Hawking has died, aged 76. In a statement his children, Lucy, Robert and Tim, said: "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." NASA paid tribute to one of modern history's titanic minds, referencing a message he passed to astronauts on the International Space Station. https://twitter.com/NASA/status/973787392590172160 Hawking experienced microgravity himself during a zero-g flight. He said that those who knew him well described his smile during that flight as "the biggest they had ever seen" and that the moment provided "true freedom." Other tributes have poured in for the cosmologist. https://twitter.com/timberners_lee/status/973778930581803009 https://twitter.com/neiltyson/status/973772335537893377 https://twitter.com/kumailn/status/973772005467025408 https://twitter.com/CarrieHFletcher/status/973847582794448896 https://twitter.com/eugenegu/status/973846440970776576 https://twitter.com/Cambridge_Uni/status/973798360632168448 https://twitter.com/ProfBrianCox/status/973822019925086208 https://twitter.com/astro_timpeake/status/973813845193084928 https://twitter.com/sundarpichai/status/973775734660624385 https://twitter.com/indyfromspace/status/973771489336897536 https://twitter.com/jeremycorbyn/status/973841825839525888 https://twitter.com/C4Paralympics/status/973836792519626753 https://twitter.com/CarolineLucas/status/973831918579044353 https://twitter.com/Jeremy_Hunt/status/973831345469345792 https://twitter.com/SamiraAhmedUK/status/973833462288388096
