A new model of gravity is offered at:
newbielink:http://www.my-read.com/What_is_gravity.html [nonactive].

This new model proposes that since:

(1) a body accelerating toward another body due to gravity seems driven only by the other body, i.e., something that the other body is influencing is causing it to move; and

(2) bodies accelerated in space void of gravitational fields experience gravity-like pushes on them as a result of the acceleration per Einstein's equivalence theory in general relativity, i.e., when bodies are accelerated in space, something pushes against them; and

(3) the units of the universal gravitational constant reduce down to a volumetric consumption rate per unit of mass (cubic-meters per second-squared per kilogram in the mks system of units;

gravity can be modeled as the flow generated toward a mass as that mass consumes the vacuum around it. 

Mass consumes vacuum at the rate specified by the universal gravitational constant.  The greater the mass the more vacuum consumed per unit time and the stronger the flow of vacuum toward the mass.  The flowing vacuum drags unrestricted bodies with it toward the consuming mass, producing the effect of gravity.

The model acknowledges that while vacuum is not commonly thought of as a substance (not matter or energy as we know them), Einstein's equivalence of gravity and acceleration in general relativity suggests that the vacuum does interact with matter and energy.  Vacuum is the only thing in empty space that can push against bodies.

The suggestion that mass is constantly consuming vacuum may also provide some insight into its nature.  Does mass exist because it is burning vacuum?  Is the consumption of vacuum vital to some other aspect of a stable universe and mass is a fortunate byproduct?  Who knows?

What are some of your thoughts on the proposal?

Gravity is a natural consequence of the quantum nature of electromagnetic fields. The nature of the field is that it always moves as a ripple of potential electric and magnetic amplitude driving points of saturation through space. Left alone, the points always move in a straight line. But when the points of saturation move through the fields of others they must reach saturation at an offset toward increasing field strength of the other fields.

It is a little difficult to get your head around it, but when you see it, it is logically demanded.

I'm holding out for the relativistic view of it being the non-linear shape and density of space-time.

[yor_on]

Yep, the troughs and heights of SpaceTime.

Well, there is the little problem that electromagnetism doesn't work to attract everything, while gravity does. That would be an empirical problem.

I don't know if you read it and didn't understand it, or that you understand it and don't accept it as possible.

It seems consistent to me. Electric and magnetic fields extend out forever diminishing in amplitude as the square of distance from their point origins. The points of the fields origin are saturated electric and magnetic amplitude. Points of origin achieve saturation with the help of diminished fields in their path. So saturation happens at a very slight offset toward increasing field strength of the diminished fields.

That is speculation; it may or may not be what happens; but it is consistent with observations; and it does work to produce the effect.

The observations and their implications are simple and clear.

Newton observed that massive bodies that are seemingly unconnected tend to move toward each other.  Something has to be causing the motion.  If the bodies are not connected, the simple explanation is that something exterior to the bodies must be pushing them together.

Einstein posited that a man in a closed chest, in deep space that is void of gravity, feels the sensation of gravity if a constant acceleration is applied to the chest.  Again, something in the void of space must be pushing against the man when he is accelerated.

The acceleration a body A imparts on body B is proportional to the mass of body A, and the inverse of the square of the distance separating A and B.  The dimensions of the proportionality constant (the universal gravitational constant), Newton-meters-squared per kilogram-squared, simplify to cubic-meters per second-squared per kilogram, which implies that each kilogram of mass is processing a volume of something per unit time.  Since the constant is negative, the processing the mass does appears to be either draining or consuming something.

Together, these seem to suggest that something in empty space, or space itself, pushes against matter to create the effect of gravity.  Since there is no indication of coulombs involved in the observations, it seems unlikely that gravity involves electromagnetism.  Because gravity seems to be pushing masses together, the motive force appears to originate away from, and move towards, the gravity source, like water moving toward an open drain, pushing objects with it.  This seems contrary to the idea of the source mass emanating particles (gravitons) that interact with objects they encounter, causing the objects to move toward the gravity source.  Both of these approaches to gravity have been pursued for many years with no conformation; which seems to suggest that, perhaps, they do not represent the true nature of gravity, just good approximations on some level.

Atom Smasher, I appreciate your efforts and will spend some time evaluating your theory. But I see a few problems with your theory. For one how do you explain the link between gravitation effects and the electromagnetic effects? For example, when objects travel near a gravitational mass, their acceleration is doubled as they reach the speed of light.

Sir Arthur eddington's observation of the bending of light around the sun during a solar eclipse was considered the first proof to einstein's theory of gravitation. However, the important fact of that experiment was that light appeared to bend twice as much as gravity would of bent a stationary object relative to the surface of the sun. That's why it is said that gravity is a bending of space itself, gravity has an additional component for relative velocities. Your theory provides a conceptual picture for an acceleration, but that picture doesn't appear to add up when you consider moving sources.

The other problem I have with your theory is that it doesn't appear to have a purpose. It's not simpler, and it doesn't predict anything new. So why this model of gravity?

Please provide a reference for the point made in your first paragraph. I am not aware of an observation supporting this claim, nor can I see how it connects gravity to electromagnetism based on what you offered.

The claims made by Eddington from his photographs of the eclipse in 1919 are commonly referenced as proof of the bending of light predicted by general relativity.  However, there have always been questions surrounding the validity of those claims.  The quality of the images on the photographic plates and the quality of the evaluation of the images continue to be questioned even today.  Not saying that it is wrong, but many people then and now were not convinced of the result reported.

Finally, the purpose of the theory is to explain the source of gravity.  Not how gravity behaves, but what causes gravity to happen.  Newton conceded that he did not know what caused gravity and Einstein's warped space still does not explain why the space warps, only that it does around massive bodies.  As far as I know (and I admit I don't know everything there is to know), the mechanism that causes gravity is still unknown.  We've spent a lot of time and money trying to devise experiments to validate what we desire gravity to be in order to support our theories, but I haven't heard that it has been pinned down yet.  If you know something different, please share it with me.

I'm holding out for the relativistic view of it being the non-linear shape and density of space-time.

Of course that is the mainstream view. My only problem with it is that you must consider space-time as variable. I have never found it necessary to do that. All the workings of the universe are much more easily explained without it.

Even time dilation?

well atomsmasher, if you don't believe that gravity bends moving objects more than stationary ones than we are at an impasse. We disagree as to what experimental evidence says.

Yes; especially time dilation. It is case number six in the evidence.

[thebrain13]

If something has to push on another to make it move, how do you explain the effects of quantum entanglement? Quantum Entanglement shows that objects here can affect objects way over there. And recent experimentation, has shown that it's not just random spins that are affected.

There is a new experiment that shows that objects can entangle momentum together. Meaning if you had two objects entangled regardless of how far apart they were their velocities would affect each other. Not many people know of this yet though, modern theory has some catching up to do. But even without this new experiment that appears to fly in the face of ether/stationary frame logic (and a lot of other things as well). I really don't see any reason why ether is needed to explain any experiment. It's also a step in the "more complicated" direction, you have to assume one more thing.

Yes; especially time dilation. It is case number six in the evidence.

If I've understood that explanation correctly, the relationship between movement and time-dilation should be linear i.e. the degree of time-dilation is proportional to the speed, but the experimental evidence supports the Lorentz solution where the degree of time dilation is proportional to the square root of the speed.

[Vern]

The Lorentz solution is exactly correct. I think your assumption about linear speed is invalid. It doesn't take into account the forward to back reduction in distance. Taken together the two causes follow the Lorentz transforms.

Link it.

It's not a question of linear speed but of the relationship between the speed and the degree of time dilation, which appears to be linear.

[Vern]

I understood your first response. I suspect that the relationship is not linear because the distortions do not operate independently but must be taken together. Each distortion affects the other. The interrelationship requires the Lorentz solution. It is interesting that Poincare who completed the Lorentz transforms knew the possibility of the electromagnetic nature of the universe.

Your statement is not correct. It is only theory. The idea that a remote object takes on a certain state when its entangled partner is observed is theory. There is no experimental evidence of it.

Statements like this show up continuously because the underlying philosophically unsound Quantum theory is never questioned.  However, there has never ever been a single experiment that upholds this most fundamental part of the theory.

Edit: Most fundamental part: An object with equal probability of existing in several states takes on the observed state at the time of observation.  Before observation it exists in a superposition of all its possible states.

The observed states of entangled particles could have existed from the time of the particles creation. There is no experimental evidence that suggests otherwise.
