Since there is a process of matter creation in the DSSU, doesn this represent a violation of the sacred conservation of energy rule? And hence invalidate the theory?
In terrestrial physics the conservation of energy law is accepted as being valid. It means that matter is neither created nor destroyed; and of course, when we speak of matter, the term includes both normal energy and frozen energy (commonly called mass). In astrophysics, however, things are not as constricted. The creation (‘formation’ is the more accurate term) of matter-and-energy is permitted —in fact it is essential. You simply can’t have a universe without it. Practically all theorists use the concept of matter creation. The subject of serious debate is not IF matter is being created but rather HOW. The vast majority believe that it was created all at once long long ago in some spectacular big bang scenario. A minority of theorists, on the other hand, believe that matter formation takes place continuously in a sedate steady state universe. Understanding the essential ingredient of matter formation/creation to any functional theory of the universe means that the various Big Bang
