Why change the definition of mass? This is a property that is used throughout physics equations. Changing the interpretation and units of mass will affect the interpretations and units of almost everything else. It is a property that is so integral to theoretical physics that no change will receive serious consideration without giving a very strong reason for the change. Even then, resistance will remain due to the prevailing opinion: Why change what has worked so well?
Theoretical physics is very successful at making predictions. Any erroneous change in mass and its units could be expected to immediately and persistently foul up theory yielding results that make no sense and are incapable of reproducing those successful predictions. Should the change to mass not harm physics equations. Should it reproduce the successful predictions and even improve on them, then that makes a very strong case for seriously evaluating its potential correctness.
That correctness would be immensely bolstered when comparing it to current theory, if it also produced clear, always present fundamental unity. That is what occurs as a result of redefining mass using only empirical evidence for direction. Any other direction allows theorists to mix their imaginings into physics equations. It is that infiltration of theoretical inventions into physics equations that can immediately and permanently cause the loss of fundamental unity. The new work that I have presented on several occasions shows that fundamental unity does exist and is incompatable with retaining theoretical inventions.
The change in the definition of mass, as indicated by empirical evidence, is that mass is the inverse of acceleration. That acceleration is the evidence for a fundamental property that remains a major part of physics theory. It reveals itself as the unifying cause for all effects. That is why my many examples of results given here in essays for all five contests are successful in producing unifying connections between all effects. I included for a second time a result that would seem to be unrelated to thermodynamic entropy. That result is the demonstration of how the two expressions for the fine structure constant are unified. They become unified for the same reasons that thermodynamic entropy becomes a known property.
