I know exactly what you are saying....but light does display both wave and particle characteristics...they just both can't be seen at the same time. I guess I am just not understanding what you are trying to get at here? And about the Newton equations.....it's risky to use them if one were to live on, lets say murcury. that was a problem that Newton and scientists after him had, were pertubations in Murcury's orbit and a rogue planet in between Murcury and the Sun. This is all cleared up with Einstien's formulas and physics....I am not trying to say that Newtonian mechanics are obsolete, they are extremely usefull in basic understanding of space and orbits and gravity and stuff like that, but if you REALLY want to know how things are going to work, for exact predictions, you had better go with Einstein's equations.
