Building on work done in 2015-2018, the standard text on subduction theory is a collection of relativity debunking and reformulation, ether experiment test results, and 4D graphics. The history of the thruster created in the research is covered and the 4D manifold theory is explained. Includes exclusive findings and test results. The textbook is the main outlet for the research currently and is not like a typical textbook, organized chronologically. this text in the current version includes only 43 pages but is being updated to include 300, as the material is available but is currently being added in.
