Abstract

Even though a medium that carries sound clearly exists, the question regarding what exactly the transmission speed of light is in relation to the medium remains unknown.
 This has led to various theoretical contradictions involving travelling objects.
As a result of our pursuit of the medium of light, we discovered a ‘law of the speed of light’, and here, we report the findings. If this theory is correct, it would have an impact on other research fields such as optics, GPS system design, frame theory of moving objects and space engineering.


1. Introduction

1.1 Consideration of what light travels through
 In 1887, Michelson–Morley experiment (cf. 1.3) was carried out in order to confirm existence of the ether of light. The interpretation of its result brought about the hypothesis that the speed of light is constant.
 But, the concept of constant speed of light and the conventional theory behind it seems strange to some researchers, including us. This theory states that the elapsed time can vary depending on observed moving objects. This is based on relativistic theories (1905, A.Einstein).
 In 1913, Georges Sagnac reported an experiment similar to the MGP experiment(1), which is key to our paper. In Sagnac's experiment, differences or the so-called Sagnac effects in the optical paths of two light rays travelling in opposite directions on a circular ring rotating with respect to an inertial frame were observed. This phenomenon is likely due to the same effect as in the MGP experiment in 1925; however, the explanation of Sagnac effects includes the concept of time dilation based on relativity.
 However, our arguments are based entirely on real phenomena and are different from the explanation regarding the Sagnac effects, which are irrelevant to our paper. In the MGP experiment, the ring was not rotated. Yet, the two light rays that were split and aimed in opposite directions made a 0.25 λ difference between their optical paths. In this experiment, the times elapsed for these two rays were strictly equal.
 On the contrary, this paper was motivated by the attempt to study the true characteristics of light.  This is purely basic physics in which we study the properties of nature entirely on the basis of real phenomena and actual experiments. What induced it was MGP experiment.
 For both inertial frames and non-inertial frames, we have based our analyses on conceptually constructed geometric frames to study these physical phenomena.  But, frames cannot affect internal changes such as light. It is impossible to change the speed of ocean waves regardless of how fast a ship travels or any effort to make changes in the wave speed from the deck of the ship. The ocean waves occur as a result of the internal properties of seawater. Similarly, it is impossible to render a mechanical effect on light because light does not have mass. Modern physics assumes that physics depends on the conceptual frames created by humans. This assumption has led to strange hypotheses of time and space, leading physicists to cover the contradictions arising from them.
 Therefore, we feel the need to take on a new perspective. This perspective takes a stance of understanding nature based solely on its phenomena. Instead of frames, there might be an interactive field where natural systems are driven. What kind of real space would that be? This paper reports a discovery of a real picture of nature—a law of nature—based on the above perspective.


 1.2 Mysteries and contradictions in the pre-existing theory of light speed
  Discussions regarding travel mediums for light have been addressed by the ether theories *2. It is generally accepted that ether does not exist. However, this conclusion carries some inevitable contradictions. I offer the following solution to this issue.
