Neil deGrasse Tyson Explains How to Prove The Earth is Round

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. He stated that there could be distortion in the shape like when the planet is revolving at a massive speed, it might look something bulgy like a disk but it is still a spherical or round surface. While "we have a video from space - of a rotating spherical earth", the people who believe that the earth is flat do not believe it. "The Earth is round".

Is Earth a flat surface or a spherical surface? Moving further in the video, he points out a joke about flat Earth believers who believe that all the planets, sun, moon and other celestial body is round except the Earth.

Michael Wood, a psychology lecturer at the University of Winchester said, 'One thing I've found interesting in my own adventures on the flat-Earth side of YouTube is, people are often pretty upfront about their motives.

"Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and the sun are all spheres". 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. According to Tyson, the laws of physics are universal and how energy behaves are two reasons why everything in the universe is, in fact, a round object.

"If you see the shape of Earth's shadow on the moon, it is always round".

Tyson describes an experiment performed by the Greek Eratosthenes, who lived in Alexandria around 250 B.C. Eratosthenes noticed that in the Egyptian city of Syene (near modern-day Aswan), you could see all the way to the bottom of a well at noon during the summer solstice.

"The only thing that makes a ideal circle shadow every time is a flawless sphere". The fact that a ship disappears from the view at the horizon proves 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.

"Our system needs to train you in not only what to know, but how to think about information and knowledge and evidence", Tyson says.

'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'.
