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 Massive Body, the velocity, and the direction of motion of this spectator, relative to the velocity and the direction of motion of this Massive Body, does affect the measured velocity value of this Massive Body, by this Human spectator. But, when a moving Human spectator, measures the velocity value of a Light beam, the velocity, and the direction of motion of this spectator, relative to the direction of motion of this Light beam, does not affect at all, the measured velocity value of this Light beam, by this Human spectator, which always results in a constant Light velocity value, which is also the maximum velocity value that Humans can measure.This should be regarded as a severe peculiarity, in any velocity value measurements of Light beams, by Humans, which must be also explained. Because it seems reasonable that the velocity of a Light beam measured by Humans, when the Light beam and the Human travel at opposite directions, should be bigger as compared to the velocity of a Light beam measured by Humans, when the Light beam and the Human travel on the same directions.This paper presents a prediction that Space and Time, as Humans perceive these notions, do not really exist, and Velocities (and Movements and Changes in general) are only the result of Interactions between Energies.The author of this paper presented this prediction in an additional paper titled: "A discussion related to the existence of the entities of Space and Time" (12) which is referenced in this paper.The details related to this prediction are also presented in this paper.In view of the above-mentioned prediction, that Velocities (and Movements and Changes in general) are only the result of Interactions between Energies, this paper proposes a tentative explanation, to the uniqueness and the severe peculiarity mentioned above, relating to measurements of the velocity of Light by Humans.The referenced paper mentioned above, (12) also suggests an experiment, which if implemented, and its result will be successful, might provide validity, or disprove, the predictions presented in that referenced paper, and, as a result, also might provide validity, or disprove, what is presented in this paper.That experiment is also presented in this paper.
