AI Thread Summary
A recent paper by Anatoli Andrei Vankov proposes a theory that extends special relativity (SR) to incorporate gravitational effects, improving on Nordström's work by suggesting that mass increases with gravitational potential. This theory successfully predicts the perihelion of Mercury and aligns closely with general relativity (GR) in weak gravitational fields, making it appealing due to its simplicity. However, concerns are raised regarding Vankov's treatment of the speed of light, as setting a different limit speed may be a flaw. The discussion highlights the absence of considerations for gravitational waves and binary pulsar orbital decay, which are critical tests for gravitational theories. Overall, while the theory shows promise, it may face challenges in making accurate predictions in stronger gravitational contexts.

Today I stumbled on a paper in Foundations of Physics that seems to successfully extend SR to include effects from gravitation:

On Relativistic Generalization of Gravitational Force
Anatoli Andrei Vankov
http://arxiv.org/abs/physics/0611161

Basically what he does is to improve on Nordstroem; the theory has higher mass at higher potential. That allows him to obtain the correct perihelion of Mercury, so that its predictions are approximately the same as GR for little gravitation. The theory is still not really finished but it looks promising to me, if only because of its simplicity (elementary mathematics, good for lazy people like me!). It also seems to naturally fit well with quantum mechanics.

What I suspect may need correction is the way he deals with the speed of light; I consider his choice to set c0 instead of c as limit speed (if I understood him correctly) to be a mistake.

Any other comments? (Are there other obvious weaknesses?)

There is no discussion of gravitational waves or the orbital decay of binary pulsars. It is possible that quantitative predictions are already precluded by experiment.

Thanks! Could you elaborate why you think that binary pulsars are a more severe test than Mercury?

Binary Pulsar orbits slow by exactly the amount predicted by decay through gravitational radiation. It is a precise, strong field, test. Essentially every other candidate theory that matches on the weak field tests fails to make any or an accurate prediction for this decay. While GW have not been detected directly, the success of this prediction is extremely strong indirect evidence.

OK, that will be interesting to compare!
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
