Curved space-time and MM

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>[mechanic]I'll ask you a just a single question: what's your choice between pushing graviton and GR?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>Here's the bump you stumble upon - there's no need or even the possibility to choose! GR is a phenomenological macroscopic theory that does not deal with the intricacies of low-level mechanisms that produce the spacetime appearance. Pushing gravity is considering the inner/deeper reality that may manifest itself macroscopically as GR-compatible reality. It's the same task that various quantum gravities pursue; but the "pushing gravity" does so at a very simple and intuitive level.

AgoraBoasta,

I concur on the pushing gravity view and its simplicity; plus ability to eliminate numerous ludricrus paradoxes when carried to its fullest explanation.

I am beginning to get a feel for MM but not entirely. From what I see my reaction is you have cracked the right door but then close it by making the infinity arguement before looking deeper.

From 123...0

I was really responding to mechanic's question of "Does space curve" (the curving being caused by gravity),
which I answered no, using MM's reasoning that an object cannot initiate it's own movement.

Actually, the notion of a body not being able to initiate a motion is more of a problem for the MM that for GR. Those understanding Physics will understand this. The rest will keep making just arguments of the 123...0 kind.

It is often the case of people making arguments and ending up with conclusions invalidating their very own points. 123...0 just did that in a glorified way. LoL

If I expect him to understand this, would I be asking a lot from him?

In most cases a lot.

Time to fix some cars.

I understand that to be an ad hominem attack but you haven't
answered the simple question Flandern posed: if gravity
was "just geometry", how can an object move by itself? If I
dropped a coin from my hand, how can it possibly move by itself
if gravity was "just geometry"?
