If I get two clocks. One at a very high mountain and the other is at the sea level. Why does the clock moves faster than the ones which is at the sea level?

Or look through some of the older threads in this forum - one of the SAs worked it out and posted the derivation fairly recently.PeterDonis said:And to answer it you would have to do the maths.
Gravity and time are both fundamental aspects of the universe and are intricately connected. According to Einstein's theory of general relativity, gravity is the curvature of space-time caused by the presence of mass or energy. This means that the stronger the gravitational force, the more it bends space-time, affecting the passage of time.
Due to the connection between gravity and time, clocks at different elevations experience time differently. At higher elevations, where the gravitational force is slightly weaker, time passes slightly faster compared to clocks at sea level. This is known as gravitational time dilation.
As mentioned, clocks at higher elevations are affected by the weaker gravitational force, causing time to pass faster. This is because the gravitational force is not as strong, meaning it does not bend space-time as much, resulting in a faster passage of time.
The difference in time between clocks at sea level and mountain is very small, on the order of billionths of a second. However, this difference is measurable using highly accurate atomic clocks, and it is a crucial factor in GPS technology.
Yes, according to Einstein's theory of relativity, time is relative and can be affected by factors such as gravity and velocity. This means that time can pass differently for different observers depending on their relative positions and movements.
