Speed of gravity

Newton’s Speed of Gravity is essentially right, Einstein’s is another matter.

Abstract

 

The title may appear to be contradictory, but as I will elaborate in this article, there is a big difference in concept and magnitude between the two speeds of gravity in space. Effectively, we are dealing with two different wave propagation modes for gravity ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

dimensional space-time.

 

1. Introduction     

 

 There is a debate on whether the speed of gravity propagates at the speed of light as Einstein said or whether it is extreme superluminal like Newton said. It is an established fact that unlike light, gravitational affects do not display aberration effects. This alone is sufficient to satisfy Newton, but Einstein says the speed of gravity is finite and equal to the speed of light. It is obvious that there is then a propagation delay for gravity to reach across and influence other matter. But proponents of Einstein’s speed of gravity carry out a lot of mathematical jugglery and appear to show that the aberration due to this delay is exactly cancelled out to zero, at least for stable orbital motion. I cannot see how a physical fact can be cancelled out by any argument. One physical reason they argue is, that Einstein’s gravity is a space-time curvature effect and therefore is a local action rather than having to act across distant space. This is not a valid argument, because the local conditions of the space-time curvature which directs the orbital geodesic motion of matter is dictated by the far distant gravitating mass. There will always be a delay to update the local curvature conditions and in turn the direction gravity acts must point towards a retarded position of the source. Let me clarify on this, if two bodies are held far apart and let loose with the same velocity in a parallel direction they will each feel each others gravitational force pointing towards each other at the moment of release. That is, the space-time curvature field was correct at first. Soon after they are released with the constant parallel velocity we would assume that they are in an inertial frame of reference and both continue to coast at the same velocity. Each body will send out space-time curvature update signals at the speed of light announcing their current locations continuously from along their trajectories. Because of the finite delay, they will each see a curvature from the other pointing to a previous position in time, which must bring about aberration effects for gravity.

 

These incompatibilities and the fact that there is no clear experimental evidence to date are good reasons to look into other ways of how gravity speed can be superluminal. Einstein’s speed limit maybe a different manifestation of space-time waves. Is it contradiction again? Not quite, as explained below, basically, Einstein’s description of the curvature of space-time as the cause of gravity is essentially correct, but the speed of ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

This is extreme super luminal, as it should be. I hope I have given a reason for why gravity wave experiments have failed so far, possibly no experiment on earth can detect the kind of speed given by equation 8.

 

3. Conclusion

 

I have hypothesized a possible scenario for gravity to operate as expected without aberration. I stated that the Einstein’s speed of gravity at the speed of light is not the ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

observations.

 

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

extreme superluminal speeds. After all Newton may have been right with respect to the speed of gravity. Like T. Van Flandern suggests may be the weird effects of non-locality in quantum theory is communicated by gravity waves at these extreme superluminal speeds.
