Neil deGrasse Tyson Explains How to Prove The Earth is Round

There is a small group of people known as Flat Earthers who indeed belong to the Flat Earth Society who claim that the Earth is flat but it definitely isn't.

Is Earth a flat surface or a spherical surface? He also explained why he thinks some Americans still believe the earth is flat, blaming our educational system and one thing most would consider to be a basic human right: the right to say whatever you want.

"What's odd is there are people who think that Earth is flat but recognize that the moon is round", Tyson says.

Flat-Earth-curious cricketer Freddie Flintoff said in a podcast a year ago, 'The middle is the North Pole, around the outside is the South Pole which is like a big wall of ice.

Tyson opened the nine-minute show by mentioning the most obvious proof of all, a video taken from space that shows the planet as a rotating sphere. Gravity wouldn't work like it does on our planet if Earth were flat, due to the center of mass being in the middle of the disc instead of the center of a sphere, so that's right out the window. He pointed out how a square flat Earth would not only look different from all-around planets and celestial bodies but also behave differently. His view differs from that of astronomer and author Stuart Clark, who told Business Insider UK earlier this year that he believes flat-Earthers are simply being amusing by saying that Earth is flat. "Who's ever seen a flat shadow?"

'They'll say that they find it more appalling to believe in the universe as a huge, uncaring place, and that it seems more reasonable to imagine Earth was made for humans like a ideal snow globe'.

Bodies that have a flatter shape have been compressed because they rotate extremely fast, which the Earth does not. Scientists generally believe that asteroids do not have enough gravity to draw their masses into the shape of a sphere. A lunar eclipse is caused when the Earth is directly blocking the Moon from sunlight, and the Moon is sitting in the Earth's shadow. Those who have chosen to believe in the flat Earth theory even in the face of thousands of years of scientific observation from every single continent will simply brush it off as "lies" anyway because that's just what they do.

And then there's the much more straightforward argument that if you watch a ship sail off, you'll eventually see it disappear into the horizon, and it would only disappear from view if it's moving on a round surface.

If there is anything that flat-earthers prove, Tyson identified that it's the current educational system's failure to teach critical analysis to students.
