Time Dilation

Time dilation is a fundamental concept in Einstein's theory of relativity, which states that the passage of time is relative and can vary depending on the observer's frame of reference. It is the phenomenon where time appears to pass slower for an observer in motion relative to a stationary observer. Proper Time and Observer Time Proper time is the time measured by a clock that has the same motion as the observer, while observer time is the time measured by a clock in a different frame of reference. Observer time is always greater than proper time, and this difference is what constitutes time dilation. Examples and Applications Time dilation has been observed and studied in various contexts, including high-speed travel, gravitational fields, and even in the behavior of subatomic particles like muons. For instance, if a spaceship travels at 95% of the speed of light to a planet 9.5 light-years away, the crew would experience time dilation and perceive the trip as taking only 3...
