This is due to the phenomenon of length contraction, predicted by Einstein's theory of special relativity. Objects in motion appear shorter in the direction of their motion relative to a stationary observer. This phenomenon is known as length contraction, which is a consequence of special relativity. As the object moves faster relative to the observer, its length appears shorter in the direction of motion.
