Astrophysicist gives 3 easy tests to prove Earth is not flat
Slamming flat-earthers, American astrophysicist Neil deGrasse Tyson has mentioned three basic tests to prove Earth is spherical and not flat. Tyson argued, during lunar eclipses, flat Earth would cast a striped shadow instead of round. He added that angles of sunlight in multiple wells wouldn't differ and a sailing ship would never go out of sight if Earth was flat.
