Part I, II, III
In this multi-part article, I will attempt to explain the cause of gravity. My explanation is based on the premise that normal matter is immersed in an immense lattice of energetic particles. I will argue that gravity is instantaneous and is a by-product of a specific type of interactions between normal matter particles and lattice particles. In today's post, I go over the state of Newtonian and Einsteinian gravity theories and I explain the nature of physical cause. If you have not already done so, please read Physics: The Problem With Motion and Understanding the Lattice before continuing.
Newtonian Gravity and General Relativity
Newtonian gravity assumes that gravity is instantaneous whereas Einsteinian gravity claims that gravity travels at the speed of light. Both theories agree that the gravitational force between two bodies is inversely proportional to the square of the distance between them. Newtonian gravity theory is simple yet extremely accurate, so much so that it is the theory used by NASA and other space agencies to place satellites in orbit and send probes to other bodies in the solar system. General relativity, by contrast, introduces all sorts of strange and convoluted complexities in order to explain why gravitating bodies behaved as if gravity acted instantaneously. The relativist explanation fails for two reasons, in my opinion. One is its lack of parsimony and the other is that it appeals to magic (more on this in an upcoming post).
Publicly, when asked about the cause of gravity, Newton offered his famous hypotheses, non fingo response. However, privately, he speculated that it was the result of some type of flux radiating from every massive body and traveling in straight lines and in every direction. This would explain the inverse square law of gravitational attraction. Of course, the flux hypothesis would not explain the instantaneous nature of gravity unless one assumed that the flux moved at infinite speed, at which point the flux explanation gets into serious trouble.
Most relativists claim that gravity is caused by the curvature of spacetime. When it is pointed out to them that spacetime is just a fictitious math construct, they will either admit that they don’t know or assert that physics is not about the why of things but the how. Whatever. Some relativists are trying to revive Newton’s flux idea by proposing the existence of an intermediary massless particle called the graviton. One of the problems with the graviton hypothesis is that the graviton has never been observed. Another problem is that gravitons are affected by the same spacetime curvature that they create. This results in a troublesome infinite regress that brings down the entire house of cards. From my perspective, the graviton hypothesis is dead on arrival.
A cause, in physics, is an imbalance and an imbalance is a violation of a conservation principle such as the conservation of momentum, spin orientation or energy. What we observe as gravity is nature’s way of correcting one or more imbalances. The correction is an interaction that manifests itself as gravitational attraction.
In my next post, I will explain what type of imbalance causes gravity and what generates the imbalance.
