Time dilation

From the local frame of reference of the blue clock, the red clock, being in motion, is perceived as ticking slower (exaggerated).

What would time dilation look like?

What is an example of time dilation in real life?

Time dilation arises in two situations. In one case, time appears to move slower the closer you are to a massive object, such as the Earth. So a person hovering in a hot-air balloon, for example, actually ages faster than someone standing below. Time also ticks by faster for someone at rest relative to someone moving.
