“Hey, man on the internet, why don’t you drive to the edge of the Earth and take a picture? Then post it. (Stars, they say, move in a plane 3,100 miles up. Tyson’s tactic is reminiscent of the quippy clapback fellow science communicator Bill Nye gave to flat-Earthers in April, which also invoked the use of images to prove that the Earth is not flat. Earth's day and night cycle is explained by positing that the sun and moon are spheres measuring 32 miles (51 kilometers) that move in circles 3,000 miles (4,828 km) above the plane of the Earth. If the Earth were flat, plate tectonics the movement of rigid plates that make up the planets crust wouldnt work either, says James Davis, a geophysicist at the Columbia University. This, obviously, is never going to happen. If the Earth was flat, the shadow it would cast on the moon’s surface when it got between the sun and the moon would, in turn, look flat, as it does in Tyson’s photo. This is possible because the Earth is both spherical and huge. During a normal lunar eclipse, we look to the sky to see the moon go completely dark - a consequence of the Earth’s shadow blocking light from the sun from reaching the moon. Here is an interactive Flat Earth Model that can explain Sunrise, Sunset, Moonrise, Moonset, Moon Phases, Moon s apparent rotation, Sun s position on. The major claim in flat Earth theory, of course, is that it is flat. Here, he lets the (obviously photoshopped) photo speak for itself. an early big-name supporter of the movement - but this time he exercises unusual verbal restraint, to great effect. It’s not the first time Tyson has gone after flat-Earthers - he famously went after rapper B.o.B.
