By Ananya Choudhary 11A Time dilation is a concept from einstein’s theory of relativity, describing how time does not pass the same way for everyone, everywhere. Depending on two main factors- speed and gravity, time can move slower or faster for different observers. This means that time is not absolute, but rather flexible, depending on conditions in space and motion. According to einstein’s special theory of relativity, when an object moves at extremely high speeds, close to the speed of light, time appears to slow down for that object relative to someone who is not moving. For example, if a person were to travel in a spaceship at very high speeds, time would move slower for them than for people left behind on earth. To the traveler, everything would feel normal, but when they return, they would find that much more time had passed for those who stayed behind. This effect has been observed in real world experiments, including with highly accurate clocks flown on airplanes or orbiting ...
