Time Dilation Explained
Moving clocks experience time differently depending on their speed relative to an observer. When a spaceship travels at a significant fraction of the speed of light, the time experienced by those onboard is less than that measured on Earth. Proper time, measured by a clock present at both events, represents the shortest time interval possible, highlighting the fascinating effects of relativity on our understanding of time.In this clip
