Understanding the Propagation of Light in the Absolute Vacuum

Light, or any other form of electromagnetic waves, can propagate through a vacuum without the need for a medium. This unique property raises the question of how exactly light propagates through this three-dimensional "nothingness." To explore this, we must first understand what constitutes an absolute vacuum.

The Absolute Vacuum: A Journey from Volume to Nothing

The absolute vacuum is paradoxically "nothing" in a full-dimensional physical sense. However, by descending from a physical three-dimensional object to its constituent dimensions, we can see that the absolute vacuum is indeed everything. Let us embark on this visual journey:

Three-Dimensional Volume: An object has a physical volume in three-dimensional space. Two-Dimensional Plane: A single side of an object represents a two-dimensional plane, a line within which is a one-dimensional distance between two points. Dimensionless Point: A point is a dimensionless coordinate, the best physical description of a vacuum, as it has no physical volume or definite size.

With this understanding, we can see that light can be described as information echoing through dimensionless points in the absolute vacuum. This speed of propagation occurs instantaneously, as the coordinates of the absolute vacuum are dimensionless.

The Cycle of Electromagnetic Fields and the Role of Light

Light propagates through the vacuum via the continuous interaction of electric and magnetic fields. Here is a simplified explanation of this process:

A variable electric field induces a corresponding variable magnetic field in the vacuum. The changing magnetic field then induces another variable electric field in its vicinity. This cycle of induction proceeds through space at the speed of light.

While it may seem that a continuous medium is necessary for the propagation of light, this is not the case. The primary source of the initial variable electric field can be attributed to various fluctuating phenomena, such as:

The fluctuation of electrons in atomic energy levels. The fluctuation of radioactive nuclei. The change in direction of electrically charged particles. The fluctuation of electrons in electronic circuits.

These fluctuations create ripples in the electromagnetic field, which propagate through the absolute vacuum as light.

Clarification on the Speed of Light

For a deeper understanding of the speed of light, I advise reading answers to questions on the acceleration of light beyond c for more detailed insights.

Through this exploration, we can appreciate that the propagation of light through the absolute vacuum is a timeless echo of physical events, informational in nature and occurring across dimensionless points. This phenomenon provides a fundamental insight into the nature of light and its unique ability to travel through a seemingly endless "nothingness."
