The TYCHOS forum
The TYCHOS forum (opens in a new tab) started in 2022 and is a companion to the TYCHOS book and 3D Simulator.
Description: “This forum is dedicated to discussions of the TYCHOS, a new geo-heliocentric model of our Solar System researched and developed by Simon Shack. The Tychosium 3D simulator is developed by Patrik Holmqvist.”
Everybody are welcome to participate. But a requirement before posting is to read the TYCHOS book. This is fully understandable, since many questions which I have seen on the forum is already explained in detail in the book.
