The Post-modern Explanation of the Refraction of Light

Subtitle: Post-modern Corpuscular Theory

“Do not bodies and light act mutually upon one another; that is to say, bodies upon light in… refracting it…”

Sir Isaac Newton

Author’s Note: The explanation of refraction as presented in this article emanates from absolute science which is the new foundation by which we investigate and understand the phenomena of nature. So, a complete understanding of this article will only follow from a composite study of my other articles and The Theory of the Universe.

Refraction is an everyday observed property of light. But why does it occur? In this article, I want to show you an understanding of refraction that goes beyond the undulatory nature of light to the very essence of light as a limit of inertia.

Basically, refraction is defined as the deflection of light when it moves through the interface between one medium and another, both of different densities. This property of refraction has been interpreted to be due to the wave nature of light. 

Now, what’s interesting about post-modern physics is that the availability of The Theory of the Universe gives us advantageous hindsight at the development of science, and in regards to refraction, we will make reference to Newton’s corpuscular theory.

While both Newton’s corpuscular theory and Planck’s quantum theory proposed the particle nature of light, Newton’s corpuscular theory views light as tiny particles called corpuscles is a description closer to the nature matter than quantum theory which views light as chunks of energy called quanta.

So, unlike quantum mechanics, the corpuscular theory describes light as one would describe matter. This is important in the post-modern explanation of refraction, even though we shall be modifying in a fundamental manner the corpuscular theory of light.

If there is anything refraction informs us about light, it is that the presence of matter affects the way light travels. This becomes evident when we are observing the motion of light in a transparent medium like water.


The speed of light changes when light moves from one medium to another. Why? I will inform you in this short article, and it will be the background upon which we shall build the new understanding of the cause of refraction.

Before now, we have concluded that refraction occurs because light is a wave which on closer inspection is not an explanation of refraction. Light maintains a constant speed c in empty space, however, this speed changes when light moves through a medium.

Thus, in a way matter and light are in interaction, and they cannot interact if they don’t share a similar property. So, what is this property? Listen, this property is inertia. I want you to now understand why refraction happens in the universe.

Now, a body moving at a particular speed would have its speed reduced when it comes into contact with another body. This occurs because both bodies are made from inertia. Inertia is the content of all matter. I call this form of inertia static inertia. Try to read this my article about this.

Bodies and light carry inertia, and we must realize that during refraction, light carries only dynamic inertia and it is also a limit of inertia in the universe, while bodies by virtue of their mass possess static inertia due to gravi-electromagnetic wave.

The new fact that light and matter carry inertia, though in different forms, is the post-modern description of the corpuscular theory. What this article informs you about refraction goes to the tangibility of reality.

When we observe light’s speed change when it moves through a stationary medium like a prism, we cannot explain how a stationary body can affect light this way. When we go to the deeper level of reality, we will realize that what varies underlyingly when light moves through a medium is its inertia.

These variations in the underlying inertia of light manifest within the domain of physical observation as variations in the speed of light. Refraction occurs because inertia is a common property of both light and matter.

The movement of light from one medium to another is simply the movement of light from one medium of static inertia to another medium of static inertia. So, in post-modern physics refraction is defined thus:

Definition 1: Refraction is a phenomenon that occurs due to the variation of the dynamic inertia of light as it moves from one medium to another with different static inertias.

Inertia is the substance of an otherwise transcendental reality. The whole concreteness and sensations we have in the universe are different manifestations of inertia. It just comes in different forms which I have discussed in some of my articles. I sometimes call inertia the materia prima of all things. This is very important.

So, basically, refraction occurs because the dynamic inertia of light is affected by the static inertia of bodies. Also, in post-modern physics, what we call visible light is the light that moves in uniform space, and in uniform space, light is the least resistance to uniform motion.

Now, uniform rest being the maximum resistance to uniform motion when light moves from empty uniform space dx into a medium, its inertia increases as it tends towards uniform rest. This new description is diagrammatically presented below:

The Refraction of Light

The above shows that light also exists in accelerated space Δx, but because it co-exists with gravity as superluminal gravi-electromagnetic wave we do not observe refraction in accelerated space.

However, if refraction were to occur in accelerated space, then the inertia of light would decrease as it tends to towards accelerated rest. This occurs when light moves from absolute accelerated space into a medium.

So, because of the two forms of space, we can distinguish between two forms of refraction. The first is uniform refraction,  while the second is accelerated refraction. These two conceptualizations of refraction take us further beyond the domain of appearances into the very nature of reality.

Now, uniform refraction is the real refraction that we observe, while accelerated refraction is hypothetical, which only describes how refraction would occur if light exists alone in accelerated space. But this is not the case as the gravi-electromagnetic wave is the non-mechanical wave in accelerated space and not light.

So now let’s define uniform and accelerated refractions.

Definition 2: Uniform refraction is the refraction of light that occurs in uniform space as the inertia of light increases due to the presence of a medium.

Definition 3: Accelerated refraction is the refraction of light that occurs in accelerated space as the inertia of light decreases due to the presence of a medium.

Thus, with light moving through different media, its inertia either increases or decreases depending on the changes in the static inertia or density. The above diagram, however, shows us that in uniform space, the inertia of light varies between uniform rest 0 and –c which is the least resistance to uniform motion and also the resistance of light in the absence of matter. 

And in accelerated space, the inertia of light varies between accelerated rest 0 and +c which is the maximum resistance to accelerated motion and also the resistance of light in the absence of matter.

Bodies act upon light because both bodies and light carry inertia, and light act upon bodies for the same reason. Newton had even suggested that heating occurs because light acts upon bodies. This also is tenable since bodies and light carry inertia. 

This article, therefore, explains to us why bodies act upon light and it presents a clearer explanation of Newton’s corpuscular theory which view light just as matter. The correlation between bodies and light exists because inertia is the basic constituent of all things.

Bodies are composed of elements, and all elements are composed of the element, which is inertia.

Until next time.
