A man used a photo of Lake Michigan near his hometown to prove that the Earth is not flat. Despite overwhelming evidence to the contrary, some people still believe that our planet is actually flat.
But Greg Pagel, using a photo taken near where he lives, is ImgurHe showed that our planet cannot be flat, and even filmed a video of it. Youtubeto.
He proves by his example that the Earth is “spherical”.
The first photo in his presentation shows Lake Michigan in Manitowoc, Wisconsin, the right photo shows the beach at Silver Creek Park in the distance – the left is the south side of the two rivers.
More photos, I found that the landscape looked flat in every photo, even when I took a panoramic photo, the landscape looked flat.
With the help of Google Earth satellite images, he shows that the planet is not really flat, enough to show the landscape of his hometown, Two Rivers and Silver Creek Park, which are 13.5 kilometers apart.
The circumference of the Earth is 40,075 kilometers, and a circular arc of 13.5 kilometers subtends an angle of 0.12 degrees. Then he shows some pictures of what a right angle looks like, a 45 degree angle, and then a 1 degree angle.
On a pie chart, a one-degree angle looks fairly straight even when magnified. So the 0.12 degree angle it presents is barely noticeable, which explains why a scene can appear flat in photographs and to the naked eye.
