Dr. Andrew Marsh (drajmarsh) is a glober and software developer. He is not active in the flat earth debate and does not have a social media presence. However, his models can be used to debunk flat earth claims such as what was claimed about TFE and the 24 hour sun. The models he created are intuitive and simple to use.

Background

Since he is not purposely active or vocal in the FE debate he is often referred to as drajmarsh. He appears to be mostly interested is writing software and has developed several web-based software models. Most of his software demonstrate different interests and are not related to either flat earth or globe arguments. His models were brought to attention of many by Jeran because they could easily demonstrate how the sun path has symmetry between the northern and southern hemispheres.

Flat Earth Debunking

According to most FE models the sun circles above the earth around the North Pole and/or Polaris. This basic circular movement would necessitate predictions that are easily testable. One test would be to see if the sun makes a counterclockwise path when observed from below, constantly rotating to the right. With the sunpath3d model anyone can see the globe prediction for the sun path and how it compares to the flat earth prediction. The difference between the two models is easily testable and more pronounced the further the observer travels south. In fact, Jeran, Josh Monday, and MxXxD are planning a Dec 2026 trip to Punta Arenas to record the sun path and compare it to a comparable northern location.

Some flat Earthers like Fred think the 24-hour Antarctica sun cannot work on a flat earth, but also can't work on a globe. This comes from a misunderstanding that the sun is local, and they believe a local sun could not be seen from Union Glacier for 24 hours while people in Canada have a normal day. However, the earthsun model clearly demonstrates how it works on a globe.

The same model could be used to debunk many of the arguments used by ShandTV. He often claims the fact that multiple people from vastly different locations can see the sun disproves the globe.
Shand has also used the July 8th argument where 99% of people are in daylight. Again the same model easily demonstrates how daylight could be visible by 99% of earth's population.

Direct Links to Apps

While many of the apps are interesting, not all would be helpful in flat earth arguments. The following is a list of relevant apps and links that may be useful.
