One thing to remember when watching Hollywood's Gravity is that it's a movie. Starring Sandra Bullock. In Space. And you have plastic 3-D glasses on. Also George Clooney is there. In real life George Clooney wouldn't be there because even though he's a well-respected actor, he's no astronaut. But for those who were under the impression this was a documentary or that Hollywood always gets things right or that this thing was anything more than Helix starring Anna Scott, astrophysicist Neil deGrasse Tyson transmitted the film's inaccuracies over Twitter last night. No spoilers.
