True Earth 101: Curvature

By katkanning on Sun, 11/26/2023 - 13:52

A mirror has to be flat to give a true reflection.  We often see crystal clear perfect reflections in bodies of water.  That means this water must be flat.  For the globe model to be true, bodies of water must curve.

Microwave communications happen over distances that should be blocked by the curve of the earth, if the earth were really curved.

Photoshopped NASA Images

Hopefully I can explain what I'm looking at here.  This is an image I took from NASA's website.  People think they are looking at a beautiful photo from space.

So I took a measurement of the distance across Mexico near Mexico City that you can pick out on this globe image.  Measurements on google maps match up with what we measure on our cars.

NASA Images vs. Photos

Screenshot from nasa dot gov. Notice how they can have photos of their headquarters in Washington, but anything to do with space is an "image" . An image is a "a visual representation of something". A photo is "a picture or likeness obtained by photography" and photography is " the art or process of producing images by the action of radiant energy and especially light on a sensitive surface (such as film or an optical sensor)". The pics you see from "space" are images created on a computer, not photos.
