NASA scientist Dr. James Garvin delivers a brutal response to Flat Earth theory, explaining that if the Earth were flat, sailors would have sailed off the edge centuries ago.
He highlights that ancient philosophers like Aristotle already understood the Earth’s roundness based on observations of stars and constellations.
Dr. Garvin points out that astronauts and robotic probes have directly observed the Earth’s curvature, further proving the planet’s spherical shape.
He also emphasises that the roundness of other planets and moons in our solar system supports his truth and how if the Earth were flat, then shadows would be the same length, regardless of location.
