Checking the absolute value of the speed of light in 1D

Journal of Modern Physics Vol.15 No.13, 2024

The self-rotating motion of the earth makes it possible to test the constancy of the speed of light in all directions by measuring the one-way speed of light. The review of the implemented experiments to test the constancy of the speed of light, based on the theory of the absolute system of reference, yields some indications that the speed of light is affected by the self-rotational motion of the earth. Newest experiments based either on the methodology of standing waves or on the Compton edge effect cannot contribute in this field of research. A proposed experiment to measuring the one-way speed of light, and the corresponding relativistic predictions, are discussed.

One-way speed of light has never been measured. This paper presents both a way to compare one‑way speed of light in opposite directions and also the beginnings of a modified relativity theory that accommodates a unique stationary frame of reference.

A discussion related to the uniqueness of the velocity of Light

Light velocity, when measured by Humans, would always result in a constant value and the maximum possible velocity that humans can measure, a claim that was presented by Einstein's Special Relativity Theory as an axiom, without any proof. The above demonstrates the uniqueness of the velocity of Light. But it should be also emphasized that the velocity of Light also presents a severe peculiarity, which is presented as follows: When a moving Human spectator measures the velocity value of any tangible substance, for example, the velocity of a moving Mass body, the velocity, and the direction of motion of this spectator, relative to the velocity and the direction of motion of this Mass body, does affect the measured velocity value of this Mass body, by this Human spectator.

The invariance of the speed of light in all inertial frames is shown to be an inevitable consequence of the relativity principle of special relativity contrary to the view held by Hsu and Hsu in taiji relativity where the speed of light is no longer a universal constant.The present approach is not only new but also much simpler than the existing approaches.

The success of Special Relativity (SR) comes from the requirement of Lorentz covariance to all physical equations. The explanation with regard to the Lorentz covariance is based on two hypotheses, namely the principle of special relativity and the constancy of the speed of light. However, the statements of the principle of special relativity are various and confusing. The covariance of physical equations and the equality of inertial frames of reference are mixed up. The equality of inertial frames of reference is obvious, but the covariance of the physical equations is a more advanced requirement. Additionally, the way that the propagation property of light is placed in a central position of SR has caused people misunderstandings towards space-time, and also there is a logical circularity between the measurement of speed of light and the synchronization of clocks. These have obstructed to correctly extend the theory of space-time from an inertial frame of reference to a non-inertial frame of reference. These are the main reasons why many people criticize SR. In present paper, the two hypotheses have been discussed in detail and a new requirement to the equations of Physics has been proposed. The requirement is the Requirement of Special Completeness, namely, the physical equations used to describe the dynamics of matter and/or fields should include the descriptions that not only the matter and/or fields are at rest relative to an inertial frame of reference, but also they move relative to this frame. Basing on this requirement and the equality of the inertial frames of reference, we can approach to SR. Thereby let the theory of Lorentz covariance has a clear and solid foundation. The constancy of the speed of light is just a deduction, not a premise. The Lorentz covariance is just a characteristic of the Special Complete equations. Maxwell equations automatically satisfy the Lorentz transformations without any modification, while Newton law of gravity does not, because Newton law of gravity is not Special Complete and Maxwell equations are. The new approach has paved a road leading towards the generalizing of the theory of space-time from the inertial frame of reference to non-inertial frame of reference without considering gravitation.

This article proves that speed of light in all uniformly moving inertial reference frames is absolute as postulated by Einstein. This is first done by considering light propagating with a speed c in all directions in an inertial frame of reference. If that frame is moving uniformly with a speed v relative to a second stationary inertial frame, we assume that light in the second frame is propagating in all directions with a different speed c= c. Consequently, modified transformation Equations are formed. The established Poincaré ellipsoidal light waves are then used to find the Equation that governs the relation of  at any speed v. The analytical solution and numerical calculations to this equation yield a value  =1. This proves that speed of light propagates through empty space with speed c independent of the speed of the light source or the observer.

It has been argued that the existence of a minimum observable interval of space and time (MOIST) is a model-independent result of the combination of quantum field theory and general relativity. In this paper, I promote this result to a fundamental postulate, called the MOIST postulate. It is argued that the postulate leads to the existence of a maximum signal speed and its invariance. This new result may have two interesting implications. On the one hand, it suggests that the MOIST postulate can explain the invariance of the speed of light, and thus it might provide a deeper logical foundation for special relativity. Moreover, it suggests that the speed constant c in modern physics is not the actual speed of light in vacuum, but the ratio of the minimum observable length to the minimum observable time interval. On the other hand, the result also suggests that the existing experiments confirming the invariance of the speed of light already provide observational evidence to support the MOIST postulate.

Here, we analyze the way the measurement of the speed of light is made and show that the relative time is not implied by the constancy of the speed of light in vacuum for all observers. It is rather the "universal" time that is consistent with the way the speed of light can be measured.

Albert Einstein was right when he proposed the constancy of the speed of light regardless of motion of the source and motion of the observer. The constancy of the speed of light follows directly from the non-existence of the ether. However, Einstein"s principle of relativity of space and time, which was derived from the light postulate and the principle of relativity, was wrong because: 1. it led to many paradoxes, and 2. absolute motion has been detected in other experiments. Special relativity was therefore a wrong interpretation of the light postulate. This paper provides a new insight that reveals the deep mystery underlying the many mutually contradicting light speed experiments. The new theory, known as Apparent Source Theory, states that the speed of light is constant and absolute motion exists at the same time. The speed of light is fundamentally constant relative to the observer but appears to be variable when measured. At the heart of Apparent Source Theory is the (one-way and two-way) constancy of the speed of light regardless of motion of the source, motion of the observer, motion of the mirror, for uniform velocity or acceleration.
