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.

Buzzfeed reports that Tyson took to his @NeilTyson Twitter account to point out some inaccuracies that occured in the film. Here are all of his tweets about Gravity.

  • The film #Gravity should be renamed “Zero Gravity”
  • The film #Gravity should be renamed “Angular Momentum”
  • FYI: Angular Momentum — The tendency, once set rotating, to keep rotating, unless another force acts to slow or stop it.
  • The film #Gravity depicts a scenario of catastrophic satellite destruction that can actually happen.
  • Mysteries of #Gravity: Why Bullock, a medical Doctor, is servicing the Hubble Space Telescope.
  • Mysteries of #Gravity: How Hubble (350mi up) ISS (230mi up) & a Chinese Space Station are all in sight lines of one another.
  • Mysteries of #Gravity: When Clooney releases Bullock’s tether, he drifts away. In zero-G a single tug brings them together.
  • Mysteries of #Gravity: Why anyone is impressed with a zero-G film 45 years after being impressed with “2001:A Space Odyssey”
  • Mysteries of #Gravity: Why Bullock’s hair, in otherwise convincing zero-G scenes, did not float freely on her head.
  • Mysteries of #Gravity: Nearly all satellites orbit Earth west to east yet all satellite debris portrayed orbited east to west
  • Mysteries of #Gravity: Satellite communications were disrupted at 230 mi up, but communications satellites orbit 100x higher.
  • Mysteries of #Gravity: Why we enjoy a SciFi film set in make-believe space more than we enjoy actual people set in real space
  • Mysteries of #Gravity: Astronaut Clooney informs medical doctor Bullock what happens medically during oxygen deprivation.
  • My Tweets hardly ever convey opinion. Mostly perspectives on the world. But if you must know, I enjoyed #Gravity very much.
