curve

By simply observing how much of an object is hidden by the ocean (or lake) horizon we can calculate the radius of the Earth. Take the three values (h = height of camera about the water, d = distance to object, x = amount of object hidden) and get the radius of the earth (r)...

https://www.metabunk.org/curve/ To use it you just put in the distance to the object in miles and your height above the surface in feet. The Metabunk curve calculator was written to provide a simple answer to the question: "how much of a distant object is hidden by the curve of the earth from...

The following post was made by @jeranism, using a fake account "PeteShasta". This is a bannable rule violation. I have been watching this forum and the videos made by Eric Dubaz, Jeranism and Mark Sargent for about a year now. I thought the flat earth dudes were ridiculous. Dumbest thing I...

A surprising fun science fact is that the curve of the earth is detectable simply by standing up. This works best with the surface of the ocean or a large lake, and it's something you can easily do at the beach. I recently gave it a go in a visit to Venice Beach near Los Angeles. With my Nikon...
