“Newton’s law of gravity applies not only to rest mass but also to inertial mass.”
Author — Post-modern Gravity, 2017
I have published an article which discusses the acceleration of light. Now, I want to set aside this short article to discuss the acceleration of gravity. Both concepts or scientific truths are indispensable in post-modern physics.
Before now, I had always understood g as representing free fall acceleration of a body. This is what classical mechanics had made me understand. It all changed when I came into contact with the principle of universal equivalence.
The letter symbol g became the acceleration of gravity itself and not the acceleration of a body due to gravity. This is all the more fitting when you realize that light is well represented in physics as a separate essence with constant speed c, so gravity must also be represented as a separate essence with its own acceleration which g now represents.
Ironically, we have for so long neglected gravity despite our tremendous efforts to understand gravity. The acceleration of gravity which produces the acceleration of bodies (due to gravity) is absent from the whole of physical science.
This absence of the acceleration of gravity further reveals to you the underlying cause of the overwhelming problem of unifying light and gravity. When we come to the realization of the acceleration of gravity, the principles of relativity become an easy aspect of gravitational interaction.
Listen, just as bodies cannot move faster than the speed of light, so also can bodies not move faster than the acceleration of gravity. This is one of the most important consequences of the theory the universe which now explicitly reveals to us the connection between light and gravity.
So, in this blog, and in all my elucidations of gravity in this post-modern era, g represents the acceleration of gravity and not the acceleration of bodies due to gravity. If you don’t take note of this, then my mathematical methods will not make sense to you, especially when I am talking about gravi-electromagnetism.
What now happens to free fall? How is the free fall of bodies then denoted or represented in post-modern physics? Remember that prior to post-modern physics, we made the distinction between two kinds of acceleration, gravitational and non-gravitational accelerations.
The letter g was used to indicate the acceleration of bodies due to gravity or gravitational acceleration, while the letter a was used to represent non-gravitational accelerations. This classical distinction between free fall or gravitational acceleration and non-gravitational acceleration can be derived from the understanding of the weak equivalence principle.
It is assumed that rest mass is what is involved for bodies under gravitational or free fall acceleration, while inertial mass is involved for bodies in non-gravitational acceleration. This simple yet incomplete understanding of gravitational and non-gravitational accelerations based on the weak equivalence principle changes under the light of the universal equivalence principle.
According to the universal equivalence principle of post-modern physics, inertial mass is what is involved for both gravitational and non-gravitational accelerations. All accelerated motion whether due to gravity or not involves only inertial mass or by extension inertial interaction.
This is why in post-modern physics both gravitational and non-gravitational accelerations are represented by the letter a and not g. In post-modern physics, g takes a higher significance as the acceleration of gravity itself and does not any longer represent the acceleration of bodies.
According to classical physics, free falling bodies above the Earth surface falls towards the gravitational or rest mass of the Earth. This is not true. Now, according to post-modern physics, free falling bodies above the Earth surface falls towards the inertial mass of the Earth.
This new truth is a consequence of another greater truth, which is that no accelerating body can accelerate greater than the acceleration of gravity. This profound truth sums the whole mystery of gravity. This is what we should have learnt about gravity from the early 20th century revolutions of relativity, and expecially of general relativity.
I want to at this point let you also know that modern relativity as it currently stands is flawed. It misses like quantum mechanics vital truths about the universe which are necessary for a simple and universal understanding of the cosmos.
General relativity which is the modern theory of gravity in the ponderable universe, should have revealed as its most vital consequence the great truth that gravity is the limit of accelerated motion in the universe, just like light is the limit of uniform motion in the universe.
Notwithstanding, post-modern physics through its conceptual framework of gravi-electrodynamics has brought this truth to us. The letter g which now represents the acceleration of gravity is an alignment to this scientific truth.
So, if g represents the acceleration of gravity which embodies both rest mass and inertial mass, and a which is associated only with only inertial mass represents the acceleration of bodies whether due to gravity or not, what then is associated with only rest mass?
This new quantity associated with only rest mass is called rest gravity. It is denoted in post-modern physics as gr. In post-modern physics, free falling bodies falls with acceleration a towards the inertial mass of the Earth, while bodies at rest on the Earth surface rest with rest gravity gr on the rest mass of the Earth.
Let’s just outline these three new quantities necessary for the post-modern description of gravity:
g → the acceleration of gravity
a → the acceleration of bodies
gr → the rest gravity of bodies
This is the new way in which the Newtonian concept of gravity has become greatly improved upon in order to truly complete and also cover the lapses in the theory. Newton’s gravitational law or inverse square law, according to the principle of universal equivalence, applies to both rest mass and inertial mass.
The acceleration of gravity g now represents this elevation and generalization of Newton’s gravitational law to the two kinds of mass in the universe. This revolutionary new understanding of gravity unravels some of the mysteries of science.
Gravity has never been real in classical and modern physics. We have been observing free falling bodies due to gravity and erroneously taking effect for cause. Bodies free fall due to the acceleration of gravity. This is the post-modern way of describing free fall which is more illuminating than saying “bodies free fall due to gravity” like we normally say.
The theory of the universe has come down to us, thus we should all come to the maturity of scientific knowledge. Our perception of gravity and all things should align with the great truths of the cosmos, of which the acceleration of gravity g is one of them.
The acceleration of gravity g which is a cause is what is indispensable to the unified description of the cosmos and not free fall which is an effect.
Until next time.
Keep loving science,
