Coming Soon:, the Worldwide Experiment

This site will allow people all over the world to form teams to measure the sun's elevation at the same time and same longitude, but from different latitudes. When the distance between the two measurement locations is known, observations of the two sun elevation angles permits the calculation of either the radius of the Earth (using a round-earth mathematical calculation), OR the height of the sun above the plane of the Earth (using a flat-earth mathematical calculation).

We're not taking one side or the other. Instead, the data gathered by many people worldwide will clearly show if the Earth is Round, or Flat.

We hope to be rolling by the Spring Equinox, Saturday, March 20, 2020.

Stay Tuned.
