Since I have not read this article I hope my comments are not too far off the mark. As I understand it, the idea is that the force of gravity is due to some sort of material fluid of particles. This being an adaption of Descartes theory of magnetism in which a flow of subtle particles explained the force. The modern idea is that particles transmit the force by some kind of exchange of momentum. This idea is vague and unclear. In particle physics it seems to have become accepted although it seems absurd. If the particle being discussed is a graviton then it would appear gravity is caused by an exchange of gravitons.
These theories were first proposed by Empedocles thousands of years ago. His theory of magnetism assumed tiny particles were responsible for the force of magnetism. But these theories do not work well at all when faced with the wave nature of the electromagnetic force. This is still a major problem today.
The main problem with the particle exchange theories is that they don't account for the change in potential during the interaction. If a force is exerted the potential changes. But theses particles don't carry potential and the theories don't explain why or how the potential changes during the interaction.
I would really appreciate it if someone can explain how this works.What causes the potential change when a force acts by an exchange of particles which carry momentum? It seems to me that in this case, only a change in momentum can occur.

In this case, the best article answering this specific question is "21st centruy gravity" from the Meta Research Bulletin issue of 2003 June 15. (Single back issues of the MRB are just $5 for non-members or $2 for current members.) The basics of the Le Sage theory of pushing gravity are in the book "Pushing Gravity".
A <i>very</i> short summary is that the "potential field" can now be identified with the light-carrying medium, now called "elysium". And the graviton medium (with much higher speeds and much smaller particles than the elysons comprising elysium) produces the momentum changes both for material bodies and for the nearby elysium. So the reason that potential also changes when a body moves is that the density of elysium falls off in an inverse linear way with distance from any mass. So when gravitons accelerate a body, they drive it to a region of different elysium density (different potential).
