Bad news, flat-earthers. Neil deGrasse Tyson is here to prove once again the Earth is indeed round.
The famed astrophysicist and author appeared in a new video through his YouTube channel StarTalk to confirm the Earth is definitely not flat.
“We have video from space of the rotating spherical Earth,” said Tyson. “The Earth is round.”
The segment could easily stop there, but Tyson digs deeper into evidence of the Earth’s roundness, including shadows it casts during lunar eclipses.
Tyson also points out humans seem to have no problem with the concept of a round Sun and every other planet, yet believe the Earth is flat.
Although talk of a flat Earth appeared to take off within the sports world (hello, Kyrie Irving), last year, sudden interest in the movement goes beyond 2017. A look at Google search trends for “flat Earth” show interest surging since January 2016.
Tyson chalks up the rise in flat earth interest two things: living in a country that protects free speech and also hosts a “failed” education system.
“Our system needs to train you not only what to know, but how to think about information and knowledge and evidence,” said Tyson. “If you don’t have that kind of training, you’d run around believing anything.”
