Neil deGrasse Tyson may be a huge Star Wars fan, but there were certain scientific issues he had with the newest movie, The Force Awakens, that he took to Twitter to address.
Before we get into it, though, here's your spoiler alert if you haven't seen the movie.
In a lengthy series of tweets dedicated to informing the Twittersphere just where Abrams went wrong, Tyson tackled various issues he discovered within the film, including the giant new weapon wielded by the First Order to destroy the Republic and the way BB-8 rolled around.
According to Tyson, BB-8 simply couldn't have slid around the sand planet of Jakku because the combination of his metal exterior and spherical shape would have led to uncontrollable skidding. Tyson did say, however, that BB-8 was by far the cuter droid when compared to R2D2.
When it came to the "Sunsucker" — the weapon that allowed the First Order to eviscerate a handful of planets at once — Tyson pointed out that if that technique was tested in real life, it would have disastrous consequences.
The First Order's home base planet would have also been vaporized in the attack, and when the weapon was detonated, it would have destroyed "tens of thousands of planets," not just a handful.
Tyson offered his opinion on a few other scientific discoveries he made while watching the film, including what kind of food Rey was eating at the beginning of the movie, before moving on to personal jokes.
Of course, his decrying of various scenes in Star Wars has lead to some people being pretty upset and reminding the astrophysicist that it's not supposed to abide by scientific rule.
Tyson isn't the only one pointing out interesting facts about the movie, either. Director J.J. Abrams recently sat down and divulged a ton of secrets, including which characters from the original trilogy appeared in the movie and why Kylo Ren had to kill Han Solo for the movie to work.
