Famed astrophysicist Neil deGrasse Tyson took aim at "Star Wars: The Force Awakens" and blasted some of the movie's science on Twitter.

Tyson, who hosts "StarTalk" on the National Geographic Channel and serves as director of the Hayden Planetarium at the American Museum of Natural History, has already expressed his preference for the USS Enterprise from "Star Trek" over the Millennium Falcon.

On Monday, after "Star Wars: The Force Awakens" destroyed box office records, he used the force of scientific knowledge to break down some of the movies questionable decisions. (Minor spoilers ahead).

While he gave BB-8, the tiny rolling droid, credit for being "waaaaay cuter than R2D2," he had some issues with the way it moved.

In @StarWars #TheForceAwakens, BB-8, a smooth rolling metal spherical ball, would have skidded uncontrollably on sand. — Neil deGrasse Tyson (@neiltyson) December 21, 2015

And the TIE Fighters? They would have sounded way less cool in real life.

In @StarWars #TheForceAwakens the TIE fighters made exactly the same sound in the vacuum of space as in planetary atmospheres — Neil deGrasse Tyson (@neiltyson) December 21, 2015

Instead of correcting the franchise's erroneous use of the term "parsec," the new film doubled-down on its mistake, which did not make Tyson very happy.

Unashamed of inanity, #TheForceAwakens repeats the Millennium Falcon boast of completing the Kessel Run in "under 12 parsecs" — Neil deGrasse Tyson (@neiltyson) December 21, 2015

( A Parsec is an obscure unit of distance in Astrophysics, equal to 3.26 Light Years. Neither has anything to do with time. ) — Neil deGrasse Tyson (@neiltyson) December 21, 2015

He also made an observation about the First Order's "Starkiller" base, which he said wouldn't make the galaxy's greatest weapon.
