According to the theory of relativity, as an object moves faster, time dilation occurs, and time appears to slow down for that object relative to a stationary observer. This phenomenon is known as "time dilation."
Special relativity, formulated by Albert Einstein, states that the perception of time is relative to the observer's motion. If you were traveling at speeds close to the speed of light, time would appear to pass more slowly for you compared to a stationary observer.
From your own perspective as the moving object, time would appear to pass normally. However, when you compare your experience to someone else who is stationary, it would seem that time is passing more slowly for you.
This effect has been experimentally verified and is a fundamental aspect of the theory of relativity. It has practical implications, such as the need to account for time dilation in certain technological systems, like the Global Positioning System (GPS).
So, in summary, as you move faster, time dilation occurs, and time appears to slow down from the perspective of a stationary observer.
