Warning: This article contains spoilers for Season 7 of Game of Thrones.
The seventh season of Game of Thrones forced fans to endure some serious logical leaps. Jon Snow seemingly teleported to Dragonstone and Gendry apparently moved at hyperspeed to get an ultra-fast raven to Daenerys. But according to Neil DeGrasse Tyson, who apparently was a little late to catch up to the show at this point, the season's science wasn't all bad.
Over the weekend, the astrophysicist praised how the show portrayed Daenerys Targaryen's full-grown dragons, which have the correct proportions to allow them to fly.
He also pointed out just how much hotter the White Walker dragon's fire must be to tear down the Wall.
But not all the science on the show works out. Tyson critiqued how the wights pulled the dragon out of the frozen lake to begin with.
And Tyson didn't resist the chance to bring up current events. At the end of his analysis, he got political, noting that NFL players' decision to kneel during the National Anthem isn't a sign of disrespect at all. Maybe the president should catch up on A Song of Ice and Fire.
