Time and time dilation has always been a big mystery which people have been trying to solve for hundreds of years. How does time move? Why does it run slow or fast? Does this have anything to do with our own movements?
Imagine if two people were to create clocks that measure time with light beams that bounce off a mirror. If both of them stay motionless, their clocks will work at the same rate.
However, if one of the people changes his position, his clock will slow compared to the other person’s clock because the distances change. As the speed of light is a constant, the light beam needs more time to reach the clock and to return to the mirror.
Scientists have found that if you move faster, then you will believe time moves slower. However, if you move at the speed of light, this will actually freeze your perspective of time and time won’t run slow or fast.
