Why? It's just two competing effects.InquiringMind said:

Just to be sure you are clear, neither one of these statements is true as an absolute statement. What you have left out is "relative to <something>". That is, your time ALWAYS moves at one second per second no matter where you are in a gravity well or how fast you are moving relative to something else.InquiringMind said:
If you eat too much food, you put on weight. If you exercise a lot, you lose weight. If you eat a lot and exercise a lot you should put on weight and you should lose weight. Is that a paradox too?InquiringMind said:

The Time Dilation Paradox is a phenomenon in which time appears to pass slower for an observer in a higher gravitational field compared to an observer in a lower gravitational field. This is due to the effects of general relativity, where gravity can bend both space and time.
Geosynchronous satellites orbit the Earth at a height of approximately 35,786 kilometers, where the gravitational pull is weaker compared to the surface of the Earth. This causes time to pass slightly faster for the satellite compared to an observer on the surface, resulting in a time dilation effect.
The time difference between a geosynchronous satellite and the Earth's surface is approximately 45 microseconds per day. This may seem insignificant, but it is crucial for accurate timekeeping and communication systems.
To account for the time difference, scientists use a concept known as gravitational time dilation, which is a correction factor applied to the satellite's clock to ensure it stays synchronized with clocks on the ground. This correction factor takes into account the difference in gravitational potential between the satellite and the Earth's surface.
Yes, there are other factors that can affect time dilation in geosynchronous satellites, such as the satellite's velocity and the Earth's rotation. However, these effects are relatively small and can be accounted for in the correction factor used for time synchronization.
