curvature

A flat earther showed me this video where Eric Dubay builds a small scale model consisting of block towers of the same size, and from a certain angle it does not appear to obey linear perspective, and the block towers appear to curve downward, despite apparently being in a straight line on a...

Hi everyone, this is my first time posting such a thread. Hope to get it right, in case I make any inaccuracies regarding the posting guidelines please let me know. With that said, I begin: Many here at Metabunk, and even more so on the Flat Earth forum, will know that Panorama Maker...

So, Ile d' Yeu is a small island off the coast of western France in the Vendee region. Being pretty much flat and at around 20 km from shore minimum, this makes it a good target for observing the effects of curvature. Went to Plage de Sion in St Hilaire de Riez, where the closest point on the...

My video proves beyond any doubt the earth is curved. I even give the location and details how it can be checked in person. I felt this was important since a video can obviously be faked. I only found out flat earthers still existed a few months ago and while walking on the beach at Felixstowe...

...I don't know how these images work yet -- I'm still learning!... The first one (above) was not taken using a solar filter so the sun appears bigger than it really is, then the second one, taken later (supposedly) appears higher in the sky after zooming in with camera. Zooming in should...

In this thread we'll be examining the very first image taken from space from a V-2 Missile and the claim related to it: It is claimed from “official sources” that a “V-2 Missle” was launched from the New Mexico desert on October 24, 1946, and that it took this black-and-white photo below...

Hello. I'm Teme and I want to debunk some of the FE curvature claims (observed curvature does not match the globe earth model etc.) using screencaps from FE balloon videos. I believe using videos from made by FE community itself presents a good basis for discussion, as many times other videos...

New to this forum but I signed up because a) I'm concerned about the whole flat earth issue in that people are stubbornly asserting its validity and b) they all seem to know some version of 'science' to significant degrees and so I need to educate myself in order to, well, debate them properly...

Im quite active against the flat earthers by posting actual scientific sources. Ofcourse earth isnt flat. Its impossible. My question is this. When claimed that according to the curvature charts and the various calculations ( 8 inch per mile squared) there will be something like "this distance...

Hey guys, I decided to whip up this experiment at my shop when somebody questioned a graphic of mine that I created to help demonstrate the horizon of a sphere the size of the earth, by zooming in it and showing the FOV. This was the graphic: (Yes I wrote in the wrong FOV for the last pic :/...

DarkStar presented his measurement using the Eratosthenes triangulation method to prove the globe earth model curvature is right. http://flatearthinsanity.blogspot.com/2016/07/simple-proof-for-convexity-of-earth.html Here is the heart of the proof. Simply pick a line of longitude (along which...

This thread documents the progress of planning, execution, and analysis of an Experiment conducted by Sandor Szekely (a believer in the "Flat Earth" theory) on Lake Balaton in Hungary. The goal of the experiment was to measure the curvature of the surface of a lake by shining a laser across it...

So, this supposedly shows Three Lakeway Center, in Metairie, Louisiana, a 403-foot (123 m)-tall skyscraper from the other end of Lake Pontchartrain Causeway. Curvature should show a 116m drop for that distance, and the buildings around it are lower than 116m. (Google Street, from the...

Hello! First post. I lurked a bit and this forum looks very interesting for me... I have had a look for this info here but haven't found anything yet, as a Noob, I'm sorry in advance if this has been discussed already... damn let me edit, of course this image is broken.. OK. We know that...
