The Fallacy of the Light Clock Experiment
Keywords: uniform rectilinear motion, Special Relativity
Even if an object is in uniform rectilinear motion, the relative speed of the object with respect to a stationary observer who is off the line of motion of the object is not constant. (The term 'line of motion' means an imaginary straight line along which an object moves.) In this case, the speed of the object with respect to the observer changes continuously as the object moves on. A noteworthy fact in this case is that the speed of the object with respect to the observer becomes zero at the moment the angle made by the object becomes 90 degrees. This is so regardless of the proper speed of the object (in its line of motion) or the distance of the observer from the line of motion of the object. These and other related discoveries discussed in this paper reveal that special relativity was born from the ignorance of the relative character of speed or motion.
