America is falling head-over-heels for Gravity.
But scientists say, in outer space, Sandra Bullock's character wouldn't look like she does in the film.
Astronaut Karen Nyberg famously shared the challenges of washing your hair in outer space which stands straight up without the help of gravity.
Another inaccuracy in the film is the debris that puts the movie's astronauts in danger. It is coming from the wrong direction!
Astrophysicist Neil deGrasse Tyson pointed out on Twitter: "Nearly all satellites orbit earth west to east yet all satellite debris portrayed [in the movie] orbited east to west."
But the astrophysicist also admitted, "If you must know, I enjoyed Gravity very much."
Time magazine said, "It's really beside the point to mention any scientific inaccuracies in Gravity since the movie is so gripping, so jaw-dropping, so visually, gobsmackingly good that it seems churlish to pay attention to much else."
