He claimed to have seen, using a telescope, a flag positioned at the 6-mile mark. So in 1838, the president of the Flat Earth Society used a 10-kilometer (6-mile stretch) of the Bedford Level in England to prove that the Earth was flat. You can prove that this is an optical illusion by clicking on "inspect element" and checking that it's a JPG. I hope for their sakes they're never on a train when the one next to them begins to move. They claim you can see the Sun move.Īnd since our senses cannot be fooled, the flat-Earthers are also claiming that the image below is a gif with moving circles rather than a JPG. But apparently, all the mathematical and observational evidence is not good enough for the flat-Earthers.

We can easily prove that the Earth moves and that other planets cannot possibly be orbiting it. So there will be a very specific height where the vapor starts condensing and the bottom of the cumulus cloud forms.

Pressure, volume, and temperature are all connected. As it travels, the air expands due to the larger volume (how does that work on a flat Earth?) and the pressure drops. Water vapor can only condense below a certain temperature and, especially on warm days, can travel upwards by thousands of meters. The flat bottom of cumulus clouds is created by changes in pressure and temperature in the atmosphere.
