You effectively set it to infinity. If you say "all speeds are below 100m/s", then how can c (a speed) be its official value? It's effectively infinity in that model. It's hand-wavy, yes, but obviously it works, since the maths check out. And perhaps you should do that more often. I may be wrong in the details sometimes, but you've been wrong overall all this time. My argumentation may be all over the place, my conclusions weirdly are always the same. I don't consider that "fickle minded". By the way, I'm still waiting for you to point out any mistakes in the mathematical derivation of Newtonian physics from GR. Indeed, reality does and has. If a choice has to be made between Newtonian physics and GR, GR wins hands down. Have you already forgotten about those experiments we mentioned earlier? They give the value of G just fine. Perhaps you should read an introductory text to GR. You've been talking about GR quite a lot now, but it seems you are missing the most basic understanding of it. What bends is spacetime. Coupling strength, strength of the interaction. You know, the constant of nature that turns up as a multiplicative factor in the gravitational force in Newtonian physics. It's like turning a knob to set the strength of gravity. In actuality it is you how needs to study up on the basics. You didn't even know what bends in GR. You can't even do any of the maths involved. You don't understand the process of limit taking. I strongly suggest you do the same. You might even learn something!
