For instance you have time dilation in special relativity which is said to be due to something moving faster than something else relative to it. You also have the time dilation in GR where time speeds up the further away you go from a body such as the Sun, Earth, etc. Now could it really all be due to the same thing? Is time slowing down for an object closer to the Sun the same overall process for time slowing down for something moving fast. Could it be that time dilation for both SR (moving faster in this case) and GR (gravity in this case) are due to the same thing?
