Question on gravitational time dilation

In summary, the conversation discusses the effects of altitude on the speed of clocks. It is stated that clock a, placed at the top of a mountain, will run slower than clock b at sea level. The question is then raised about the potential difference in speed between clock b and clock c, which would be placed 6000ft below sea level. It is clarified that clock b at the bottom of the mountain runs slower than clock a at the top, and clock c in a hole would also run slower than both. A helpful link is provided for further clarification.

Hello,

I am new to the site and have question. I have three clocks (a,b,c). Clock a is placed on top of a mountain, 6000 ft higher than clock b, which is at sea level. Now I know that clock a will run slower than clock b. Now if were to dig a hole 6000ft below sea level and place clock c there, would c run faster than b?

You have it backwards, clock b at the bottom of the mountain runs slower than clock a at the top. And clock c at the botttom of a hole would run slower than either, see this recent thread.

so dyslexic sometimes... thank you for the link.
 

Related to Question on gravitational time dilation

1. What is gravitational time dilation?

Gravitational time dilation is a phenomenon in which time appears to pass at different rates in different locations due to the effects of gravity. It is predicted by Einstein's theory of general relativity and has been observed and measured through various experiments.

2. How does gravity affect time dilation?

According to the theory of general relativity, gravity is not a force but rather a curvature of spacetime caused by the presence of massive objects. This curvature can affect the flow of time, causing time to pass slower in regions with stronger gravitational fields.

3. What are some examples of gravitational time dilation?

One famous example of gravitational time dilation is the time difference between a clock on the surface of the Earth and a clock on a satellite in orbit. The clock on the satellite experiences time dilation due to the weaker gravitational field in space. Another example is the time difference between a clock at sea level and a clock on top of a mountain due to the difference in gravitational strength.

4. How is gravitational time dilation measured?

Gravitational time dilation can be measured through experiments such as the Pound-Rebka experiment, which involved comparing the frequency of photons emitted from the top and bottom of a tower. The difference in frequency was attributed to the difference in gravitational potential between the two points, demonstrating the effects of time dilation.

5. Can gravitational time dilation be observed in everyday life?

Yes, although the effects are extremely small and not noticeable in our daily lives. The difference in time can only be observed and measured in extreme conditions, such as near massive objects like black holes or in high-speed situations, such as with satellites in orbit. However, the concept of gravitational time dilation has important implications in fields such as astronomy and GPS technology.
