Musician uses math to refute theory that the earth is flat

Musician Greg Pagel, 47, used pure math to definitively prove to supporters that the earth is flat that none of this makes sense.

To do so, the artist took some pictures of Lake Michigan, a place that has intrigued him since a young age. "I used to look at the horizon a thousand times and ask myself: Am I seeing a curve? Or is my mind playing tricks on me? I used to look at it a lot when I was a child."

But unlike the guys who simply assumed the earth was flat because of it, he did some calculations and, with Google Earth as a tool, was able to conclude why it looks flat even though it is spherical.

In this Google Earth image, it shows what you can see on the horizon: on the left, the shore of Lake Two Rivers; On the right is the beach of Silver Creek Park. As the beach line is curved, one cannot see beyond each point because it is blocked by the earth.

The straight line distance between the two banks is 13.5 km. To find out whether this stretch is curved or straight, he compared this route to the circumference of the earth: if it is 40, 075 km, then that 13.5 km corresponds to an angle of approximately 0.12 degree.

First, he showed what a 1-degree curve would look like on a circumference the size of the earth - which in itself is straight enough. When he showed the 0.12 degree angle then it was possible to realize that it is almost insignificant but still flat!

The problem is that our vision only captures a very short stretch of the planet's size, and that makes us not see the whole!
