# Time theory (theory of non-relativity)

- Author:
- Tomáš Košumberský

Deformation of space-time? Dark matter?? Black holes???
The author wrote the book "Time theory" and created an entirely new theory of mechanics, based on the Euclidean 4D space-time. After reading this book, you will always be clear about the physical phenomena that are real in our world, and what, on the contrary, is just science fiction!
The real world is much simpler (and much less bizarre).
Mathematics of a “simple” trigonometry reliably describes whole (space) mechanics, “mysterious” spacetime, time-dilatation and the phenomenon of gravity as well … nothing more is needed (whatever more is wrong).
With the help of Geogebra, he demonstrates the main physical principles.
