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.How do you effectively set 'c' to infinity? c is c, it is not even C.

It's hand-wavy, yes, but obviously it works, since the maths check out.Another bloomer?

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.See, do not rush to wiki or stackexchange everytime.

My argumentation may be all over the place, my conclusions weirdly are always the same. I don't consider that "fickle minded".Learn properly, make up your mind, then you will not be unclear. You are being so 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.You don't decide what is necessary or not.

Have you already forgotten about those experiments we mentioned earlier? They give the value of G just fine.Reject Newtonian and get me G, that's the question I asked, you conveniently continued with your wikis and stackeys and retracted too. You can't.

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.What bends between you and another person sitting infront of you?

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.What is "strength" in GR? Another 'unclear' stuff?

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.Bye bye. You need to study quite extensively on basics of gravity, GR will come later.

I strongly suggest you do the same. You might even learn something!Why not take help from your free/unsolicited advisors on this thread, Origin and DaveC, may be they can lift you.
