Warning: Some mild spoilers lie ahead.
Everyone is talking about Star Wars: The Force Awakens, which opened on Friday. And of course, renowned astrophysicist Neil deGrasse Tyson had to get into the mix, putting the science in science fiction.
Tyson took to Twitter to educate the public about some of the science behind the movie, with just a few mild spoilers. Here are some of his tweets.
Of course, Tyson is alluding to accusations that he played a role in the “demotion” Pluto from a planet to a dwarf planet in 2006.
Tyson’s beef comes from the fact that sound doesn’t travel in a vacuum, ie., space.
As you have likely seen in the trailers for the movie, Chewbacca is back. And it’s hard to tell if he’s gone grey. Though it’s not so hard to tell with Harrison Ford. And Carrie Fisher, well, as with all humans, we’ve aged a lot since 1977, the year the first movie in the franchise — Star Wars: A New Hope — was released.
Tyson is known for being a bit nit-picky when it comes to the accuracy of stars in the night sky in movies.
He publicly criticized James Cameron — even writing him a letter — for the inaccuracy of the night sky in Titanic. When the movie was re-released, Cameron fixed it.

With all the tweets, it’s hard to tell whether or not he enjoyed the movie. But ultimately, it doesn’t matter: the movie grossed $238 million across North America this weekend.
