Astrophysicist Neil DeGrasse Tyson Fact-Checks ‘Gravity’
Sandra Bullock’s new space blockbuster had an out-of-this-world weekend at the box office, raking in a record-breaking $55.6 million. Harvard and Columbia University educated astrophysicist Neil DeGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York, took to Twitter over the weekend to use Gravity as a teaching tool for how it really works.
