The perception of time dilation, where time appears to slow down for objects in motion, is a concept derived from the theory of relativity, specifically the theory of special relativity proposed by Albert Einstein. According to this theory, as an object's velocity increases relative to an observer, time for that object will appear to move more slowly from the perspective of the observer.
However, it's important to note that the effects of time dilation become significant only at speeds approaching the speed of light, which is far beyond the velocities typically encountered in everyday life. The speeds at which humans and objects move in their daily activities are significantly slower than the speed of light, so the observed time dilation is negligible and not perceivable in normal circumstances.
As a result, the motion of objects in everyday life, including the apparent motion of stars in the night sky, is not noticeably affected by time dilation. The stars are extremely far away from us, and their distances and motions are typically measured on astronomical timescales, which are not subject to significant relativistic effects.
In summary, while time dilation is a real phenomenon according to the theory of relativity, its effects are only perceptible at speeds close to the speed of light, and not relevant for the relatively slow motions we observe in our daily lives.
