how do flat earthers explain day and night

Have them pull out their smart phone and open up Google maps and touch the icon to zoom to their current location. Geographic layout in the original question. If you assume that the sun is at the location consistent with observations (1) and (2), person (3) cannot see the sun just being to his/her west given the This is easy to spell out if you pick the times/places such thatġ) For one person the sun is directly overhead,Ģ) Another person is due north of person 1,ģ) Another person is due east (on the same line of latitiude) as person 1.

(Eratosthenes used the fact that the rays from the sun are all parallel - I'm not giving the flat Earthers that much credit). Here we need three observation points to eliminate a possible objection of the conspiracy theorists: the sun actually isn't all that far away. This is a more modern way of doing Eratosthenes's experiment. The set of angles that they report will be inconsistent with their locations being on a flat disk laid out as in the map in the question. You need three flat Earth theorists on different continents (or otherwise well separated) all in on a (video) conference call, and have them measure the azimuth and elevation angles of the sun at the same time. This question is more focused towards convincing a doubtful scientific person using (preferably low-tech) experiments and observations. What are some good arguments or backyard experiments that could convince a layman that in fact the Flat Earth Theory is false?Ī similar question and useful related reading is What is the simplest way to prove the Earth is round?, but it focuses more on the theoretical and conceptually simple side, applicable to the proverbial 'numskull cousin'.

The Flat Earth Theory is a scientific theory, in the sense that it makes falsifiable predictions about the universe that can be seen to match observation (or not). NASA is part of a conspiracy to conceal the truth, and sends us animations and faked photo shoots.

The sun and moon are either spheres or disks floating above the earth and moving in a spiral pattern with the seasons.

The Earth is a flat disk, with the south pole blown up into a circular 'ice wall' where one would expect Antarctica to be.

I recently became aware that the flat Earth theory still exists in the 21st century, and has colored the views of a friend of mine.
