You did not grasp it. I am not trying to calculate G; I am using it to establish relationships between elements of free fall objects and secondly if it has the same value in other star systems. You have too narrow a view.

As for determining whether it has the same value in other star systems, this would involve finding gravitationally bound stellar objects, and determining their mass otherwise than by using orbital mechanics. Estimates based on brightness and stellar physics are much too inaccurate to be useful unless the constant G is hugely variable. If it were, that would have been noticed already. Sylvia.

I agree and submit that the mass of the three Alpha Centauri stars and their surface acceleration as stated in the literature are grossly inaccurate. Furthermore the value of G is defined only for the solar system and no evidence exists it is the same in other star systems.

It's value beyond that is constrained by the requirement that the orbital periods of binary stars be consistent with their separation and their masses, as estimated using the brightness (or period, in the case of some variable stars) using stellar physics. So while there's no direct evidence that the value is exactly the same beyond the solar system, there is evidence that its value is not hugely different. Given its constancy out to Voyager 1, there is no present reason to think it varies. Either way, your circular analyses contribute nothing to our knowledge. Sylvia.

Thank you for your information. I shall hesitate to calculate G beyond the solar system as the assumptions of the experts do not affect my gravity theory.

I may be guilty of some circularity of my own here, since the brightness of a star of given mass depends on the local value of G. For higher G, the star will be brighter (and shorter lived) for a given mass. However, I'd be surprised if the relationship were linear, so inconsistencies would still show (unless I'm wrong about the relationship). It should also be noted that stars get brighter as they age, even thought their mass is reducing. Sylvia.

Moon's force of gravity is greater than the Sun.Yet the Sun is 99 % of the mass of solar system.The reason for this is well known.Moon's gravity force also has the start of an objects falling much slower than object starting to fall in Earth's gravity field. Best to keep that in mind. TreBert

I see the other way.Reason stars that use up their fuel faster are brighter.Think density.Trebert

I am trying to confirm it. I have failed to confirm it in the case of stars because I was not able to get the correct values of some elements of the stars I looked at. The equation that I used showed a difference in the value of G of the sun and Alpha Centauri A, B, C. The assumption that G is the same in the universe is not supported by evidence.

The only problem is that you've not been able to research and find the correct evidence.
