A Simple Experiment to Probe the 'Relativistic Mass/Energy' Concept in Special Relativity against Asymmetry Theory Prediction

As a particle accelerates, its resistance to further acceleration increases, challenging Newton's constant mass theory. Special relativity explains this using "relativistic mass" or "energy," where momentum-to-speed ratio rises with speed due to increased energy requirements. Both "mass" and "energy" are scalar quantities, making special relativity's explanation direction-independent.

Based solely on the principle of the constancy of light velocity, a comprehensive set of ground-breaking results was derived through strict mathematics, named “Asymmetry Theory”. Aligned with all established experiments, Asymmetry Theory provides mathematical derivation of “resistance to acceleration”. Remarkably, it predicts that the ratio of momentum to speed change not only depends on the object's speed but also the direction of applied momentum. For instance, as an object's speed increases, it becomes more challenging to accelerate, yet easier to decelerate.

We propose a simple experiment involving an electron moving at a constant high speed. Apply momentum in various directions and calculate the ratio of momentum to speed change. If special relativity holds true, this ratio should remain constant regardless of direction. Conversely, Asymmetry Theory predicts that the ratio will significantly exceed 1 when accelerating the particle and drop below 1 when decelerating. The results promise to provide unequivocal insight into which theory better describes the behavior of accelerated particles.
