The possibility of travel forward and backward through space-time intrigues a vast number of people. I find it curious that many believe that Back to the Future is really possible and eventually someone will implement a process/machine to do exactly that. I, on the other hand, believe that time travel through space-time is impossible and in this book, I put forward, what I consider to be, a valid proof. The expansion of the universe and ultimately the Heat Death of the Universe means that energy is continuously lost and is not recoverable. To travel through space-time it is necessary to remove energy from the universe to move forward in time or add energy to the universe to move backward in time and that is, therefore, impossible. My purpose in writing this book is to put forward a paradigm where travel in time-space, not through space-time, is possible. Where movement about in three-dimensional space does not require energy to be either removed from or added to, the universe. Professor Da-veed's accidental discovery of this paradigm forces him to take measures to avoid being taken into custody by the FBI, DHS, and NSA because he fears that the government would weaponize ZTAD and use it to dominate other countries.
