America's favorite astrophysicist Neil deGrasse Tyson may be smarter than all of us—but that doesn't mean he can't enjoy binge watching the same shows we do. Tyson is evidently a big Game of Thrones fan, and he took to Twitter this weekend to share some scientific insight on season seven. And he kindly gave a warning that spoilers were ahead.
Tyson wasn't too bothered by the fact that frozen dead people were swimming, even though previous episodes implied they couldn't. But he straight-up labeled the way the dragon was pulled out of the lake as "bad physics."
