General relativity cannot predict or calculate anything, specifically the attributes G, g, M, m, GM, r, v, t and others of solar objects.

G, M, m are not predicted by the theory.
But the trajectory parameters r, v, t are.

If r=50000km what is the corresponding v under GR?

That's insufficiently specified. You need to specify m, and then specify 
r and v as vectors at some point in time. GR then gives you v and r, 
again as vectors, for any other time.

My gravity theory can, GR cannot.

Prove it. Do it for the v at r=50,000km from Alpha Centauri.

I would be happy to give you the t for any r in the solar system but please tell me first how GR can calculate r, v, t.

I've done that. Now your theory: Any theory of gravity would not be 
limited to our solar system. This is why I asked you to do it for a star 
other than our own sun.

If I position myself 50,000km from the centre of the sun, then I'll be 
inside it. Not helpful.

Let's say 50 million km from the centre, and at the instant in question, 
not moving relative to the sun.

Now I can project an object at an arbitrary velocity in an arbitrary 
direction. One of three things can happen.

a) The object disappears into interstellar space, never to be seen again.

b) It follows a trajectory that impacts the sun.

c) It orbits the sun along some ellipse, repeatedly returning to where I am.

Clearly there are very many different velocities that can result in (c), 
so no valid theory can possibly give a single velocity, and any theory 
that purports to do so, such as yours, apparently, has to be wrong.

Sylvia.

Let's define specific parameters: An object is in orbit around the sun at say 50,000,000km or any other distance. My gravity theory can predict in what time t it will return to its original position.

I am still waiting on Bod to tell me how GR can predict or calculate r, v, t of solar objects. I am of the opinion he can't.

I expect he can.

For this situation, with an object with a mass small compared with that 
of the sun, GR reduces to Kepler's third law. Since your orbit is at a 
constant distance, it is circular, and the semi-major axis is 50,000,000km.

You are basically correct but the orbit is not necessarily circular and Bod's claim is refuted; GR cannot predict/calculate t nor v or r.

If the orbit is not necessarily circular, then your statement that the 
object is in orbit around the sun at 50,000,000km makes no sense.

Since GR reduces to Kepler's third law, and that law gives t, it follows 
GR tives t. The value of v is obtained by simple geometry (distance over 
time). I don't know what you intend by saying that it doesn't give r - r 
is an input to the calculation.

The object is at a distance from the sun of 50,000,000km which is the semi major axis of the object. All the planets have a fixed semi major axis and at the same time are elliptical.

Kepler's third law gives t but GR does not. The phrase 'GR reduces to Kepler's third law' is ambiguous. It is either one or the other and it is not GR.

Another request: Can you tell me what is t for a semi major axis of 50,000,000km?

If you intended semi-major axis, you should have said so. Why are you so 
imprecise in your wording?

A full expansion of the equations of relativity applied to this 
situation will include a large number of terms. Given the values of the 
Sun's mass, the object's mass (considered to be small compared with that 
of the Sun) and the distance involved, almost all of those terms will be 
vanishingly small, and can be ignored. What's left corresponds to 
Kepler's third law.

I can't be bothered. Plug the values into Kepler's third law formula if 
you want to know.

It means GR is not necessary. It is superfluous.

The time for the orbit of an object at a distance from the sun of 50,000,000km 
is 70.58 days and the orbit may have an eccentricity range of e = 0 to .9999. GR could never predict/calculate this. Confirmed by you and the silence of Bod.

In this situation. Go near a black hole, and you'll find that the other 
terms are not vanishingly small.

If that's what Kepler's law says, then GR says pretty much the same 
thing (the difference lying in those vanishingly small terms). So it's 
manifestly incorrect to say that GR cannot predict this.

More honest would be to say
you have no idea how to predict it by GR. ( Neither I have )

GR is to  Kepler/Newton gravity
like a  parabolic function to linear function.

Newton gravity as a special case of GR,
as linear function is a special case of a parabolic one.

Saying GR cannot address what a Keplers laws can
as as rudiculous like saying
there is no way to interpolate points in a line
by a parabolic function.
