Yes, logic must indeed be central. Sorry to dissapoint you on all counts Tycho. You have totally misunderstood my arguments; that is because you've taken a cursory glance and reached a super quick and super wrong conclusion. On time having a zero point? I claim the exact opposite - the whole construct of time is a mathematical convenience to measure the flow of energy. Time, length, speed and direction are derived from energy flows and not vice-versa.
As for the existence of nothingness? It ties up with our concept of zero, to have a starting point, there has to be a zeroth point (a point of total emptiness devoid of energy). In any event, what does zero really mean? If theres no measurable zeroth point ...and there's none; zero goes out the window like the mathematical construct and mental bound that it is. You have to start from an equilibrium.
C is constant for a medium, just as the speed of sound is contant for a medium. I do not argue that does not vary with condition, to the contrary, if you pay close enough attention to the papers logic, you'll find that I don't treat C as a rigid constant.
