In summary, today the conversation focused on a paper in Foundations of Physics by Anatoli Andrei Vankov that proposes a theory to extend SR to include gravitational effects. The theory improves on Nordstroem and has been able to accurately predict the perihelion of Mercury. However, there may be some weaknesses in the way the theory deals with the speed of light. It also does not address gravitational waves or the orbital decay of binary pulsars, which could be a more severe test for the theory.

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!
 

FAQ: Theory of graviation for lazy people

What is the theory of gravitation for lazy people?

The theory of gravitation for lazy people is a simplified explanation of Isaac Newton's law of universal gravitation, which states that every object in the universe is attracted to other objects by a force called gravity. This simplified version is meant to be easier to understand for those who are not familiar with complex scientific concepts.

How does gravity work?

In the theory of gravitation for lazy people, gravity is described as a force that pulls objects towards each other. This force is determined by the mass of the objects and the distance between them. The bigger the objects and the closer they are, the stronger the force of gravity between them.

Why do objects fall to the ground?

Objects fall to the ground because of the force of gravity. The Earth has a large mass, which creates a strong gravitational force that pulls objects towards its center. When an object is dropped, it falls towards the ground because of this force.

Is gravity the same everywhere on Earth?

No, the force of gravity can vary slightly depending on location. This is because the Earth is not a perfect sphere and has variations in its mass distribution. However, these differences are very small and not noticeable to most people.

Can gravity be turned off?

No, gravity is a fundamental force of the universe and cannot be turned off. It is always present and affects everything in the universe. However, its strength can be counteracted by other forces, such as the force of air resistance or the force of electromagnetism.
