Sandra Bullock's hair should have been floating free. That was just one of the many things "Gravity" didn't get right, according to astrophysicist Neil deGrasse Tyson after he saw the critically acclaimed movie.

The just-opened film, starring Oscar winners Sandra Bullock and George Clooney as a medical engineer and a veteran astronaut who hit rough times while aboard their space shuttle, might have broken box-office records over the weekend, but it seemed to drive Tyson crazy with its scientific innaccuracies. The Harvard- and Columbia-educated science communicator took to Twitter to sound off, and though his tweets weren't all negative, they were quite shocking. Here is the Twitter rant: 

Tyson starts off by telling us a few changes he would make to the movie. 


Then he lists all the "mysteries" that he thinks make the movie somewhat unrealistic:

Then there are some more mysteries... 

But then he reassures the public that he did in fact like the movie. 

And just when you think its over, it's not. 

Perhaps Tyson could be a consultant next time a space flick goes into production? Just a thought.
