| I understand GR explains motion under a gravitational field a curvature of space. I have NO problem with this. The bending or light during a solar eclipse proved GR correct. But how does GR explain a stationary object exerting a force while on the surface of a planet? -- Danny Dot [Only registered users see links. ] |

| Dear Danny Dot: "Danny Dot" <don'[Only registered users see links. ]> wrote in message news:AN1Dg.3167$[Only registered users see links. ].com... Not "space"... spacetime. The force is an inertial force, as the surface of the planet accelerates the "stationary object" into a circular orbit. An orbit for which it has insufficient momentum to maintain on its own.

| Because every bit of matter tends to move towards its gravitating center which is the center of earth in a local way while altogether they move towards the solar system's gravitational center which simultaneously moves towards the galactic center and so on and so forth towards the center of the total Universe which maybe in fact more than one Universe or which could be termed 'Entirety' [including our Universe {known and visible} and if they exist more such Universes] Thomas Walker "Danny Dot" <don'[Only registered users see links. ]> wrote in message news:AN1Dg.3167$[Only registered users see links. ].com... -- Posted via a free Usenet account from [Only registered users see links. ] |
