I am very interested to comment on this question.

I note, firstly, some of the things stated by one of the well qualified answerers below. Owen Jones said, inter alia, “but it says nothing whatsoever about why the bowling ball deforms the rubber sheet in the first place.” What he really said was that Einstein, in producing his brilliant maths work was unable to provide a working mechanism for his imagined distortion of his imagined space/time continuum. This was the downfall of his theory. It works, but no one knows how it works.

He also went on to say, “So I’m afraid the best answer I can give is that nobody really knows.”

Well, if someone as well qualified as he is can state that, then I feel that I am at least entitled to an opinion.

And the pleasant thing is that you have asked for our opinions. There is nothing better that people like than giving their opinions, so here goes:

So let me start on Newton, who did a very bad thing for science. He invented an imaginary attraction force between particles and was unable to provide a working mechanism as to how that attraction worked, why it worked, and so on. In subsequent years, his theory of attraction is still unable to explain how it works and why we have an expanding universe when his force of attraction should make it shrink.

In 1978 I developed a new theory of gravitation by proposing the existence of gravity waves. It has taken forty or so years of patient waiting for technology to catch up with my imagination. My DOPA gravitational theory does the same as Newton and Einstein; it makes a proposition, but the proposition is a working proposition that has a working mechanism that accounts not just for how gravity works, but why.

In my opinion gravity is caused by the partial absorption of gravity waves as they pass through matter. My book, published in December 2018, referenced below, explains all of the details, but to keep to your question, the absorption of gravity waves relates to the density of the matter through which it passes. So, yes, the property of matter is relevant.

You can see the book at:
In very brief, I postulate that throughout the majority of the universe there is a universal omni-directional gravitation wave flux. To put it simpler, gravitation waves exist in the same way as light waves, travelling in every direction uniformly. If we look around the Earth, we can see light travelling from every direction of the universe. The same for gravitation waves (not commenting on how they are created) and hence the simple concept of a gravitational flux.

Now, consider a sphere. It is being penetrated from every direction by gravitation waves which are partially absorbed, causing a frictional drag on every atom as they pass through. This is just the same as light when it passes through glass; it’s velocity falls through internal friction drag. So, I just extended this phenomenon from light waves to gravity waves. As the gravitational waves enter the Earth’s surface and travel through the Earth, they drag on the atoms, losing a certain very tiny percentage of their strength in the process. For any particular set of waves, this drag force is resisted by the gravity waves that have entered the Earth from the opposite side, and which are thus coming up out of the Earth. However, the upcoming waves have been weakened more than the fresh incoming waves and so there is a net force on the atoms downwards. That results in our case, in a net downwards acceleration of about 9.8 m/sec/sec. It’s easy. And the waves that leave the Earth travel on outwards to become part of the universal flux once more.

The consequence is the generation of pressure as the particles are subject to the the accumulating effects of the net force. The further down the force train from the surface, the the greater the pressure created which is resisted by the inter-atomic and inter-molecular strong forces.

So that’s how planets and stars are formed. The atoms in space dust clouds absorb gravity waves in the same way and are thus driven by the gravitational drag inwards towards one another.

My theory then goes on to explain why separate bodies such as planets or stars are forced together by the phenomenon we know as gravity.

As a result of the gravitational absorption explained above, the outward-travelling, weaker gravitational waves leaving the surface of a planet or star, produce a ‘shading’ effect around it. The theory explains that a planet absorbs a percentage of the incident and transient gravity waves. Thus all around the planet there is a zone where the universal flux is weakened by a zone of weaker outgoing gravity waves. That’s fine as long as the planet is isolated, but if there is another object nearby, such as a moon or even just a tiny human, then this weakened zone allows the flux to push the objects together.

Let’s see how.

Let’s take the example of two planets in proximity. Planet A and planet B.

Planet B receives waves that have passed through Planet A. They have been weakened by partial absorption and so when they cause internal drag in planet B, it is weaker than the opposing drag from the fresh wave flux on the other side of planet B. Thus, the fresh wave fronts moving towards planet A through planet B are stronger in that direction than the waves moving away from planet A through planet B. Thus there is a simple net drag on planet B forcing it towards planet A. The same applies to planet A as does to planet B.

Both planets experience a drag towards each other. The amount of drag is governed by the density of the two bodies (this is mathematically the same as Newton’s theory, but—you observe—my DOPA theory provides the missing working mechanism) and the distance between the bodies (same as Newton but I provide a mechanism for that too).

The mechanism for the distance factor results in an inverse square type law, because of the geometry. The further apart the planets, the more influence there is from fresh incident waves on the intervening faces of each planet. Let me explain that by giving the example of two discs placed immediately adjacent to each other just a fraction of a millimetre apart. In that case, they would both provide the maximum possible gravitational shading to each other. No extraneous slightly-angled gravity waves would get in to the intervening faces of each disc. This provides the maximum possible net drag effect. But, as soon as you start to move the discs apart, then more and more angled waves pass into the intervening space between the discs and start to dilute the shading effect. On an inverse basis, as they move further apart, the gravitational drag effect becomes less distorted and less uni-directional, so that eventually, it becomes unnoticeable and the disks attract each other less and less. I hope you can see this. If not, read my book as referenced above. The coloured diagrams there will make it clear to you.

And so, there is now a theory—DOPA gravitational theory—that has a very simple mechanism to explain all the features of gravity that we observe today, including the expanding universe. We replace attraction with internal drag—it is simply the creation of a shaded ‘umbral’ zone between bodies that allows the overall flux of gravity waves to drag bodies towards each other. Straightforward.

And, in the case of a person standing on the surface of the Earth, exactly the same thing happens. We are subject to fresh waves from outer space dragging our atoms down towards the core of the Earth, and that drag is being resisted by weakened waves coming up through the Earth. The net result is that we are subject to an acceleration downwards of about 9.8 m./sec/sec. If we stand on the moon, the absorption of the waves passing through it is much less, and so the scenario provides the correct outcome: the fresh flux waves drag us downwards to the core of the moon, but they are resisted by much stronger waves coming out of the moon—they have maintained their strength through reduce absorption because of the lesser density of the moon and its material. Again, easy.

So, Newton’s equation appears to apply, but I have provided an explanation and a mechanism for why it apparently works.
