I was exposed to the flat earth theory recently. I watched a video called "the Globe's End. The New Distance to horizon" which puzzled me. Could...
An amusing anecdote about forgetting the curvature of the Earth. In 2 Miles the pipe would drop 32 inches, and have a "bulge" in the middle of 8...
[ATTACH] Walter Bislins has created a very useful tool for visualizing what things should look like from certain positions, and with certain...
[ATTACH] A classic experiment to demonstrate the curvature of a body of water is to place markers (like flags) a fixed distance above the water...
Hi guys, a while ago I came across this photo. Which I just couldn't explain. How is it possible to capture a full Earth which is 12,000km in...
Given that some people claim the curvature of the Earth is not accounted for in surveying, I thought it would be interesting to document various...
Had an idea about how to very clearly and very easily show that the horizon isn't at eye level: take some pictures of some eyes! You will need:...

[ATTACH] From past the orbit of Mars, the solar system looks a bit like the above. Earth is just a speck, not even visible here (at the end of...
This question originates from a YouTube video called "NASA Blue Marble 100% Debunked" by Flat Earth Asshole (pardon the language, but that is...
