Detailed explanation-1: -For example, time goes slower at the ISS, lagging approximately 0.01 seconds for every 12 Earth months passed.
Detailed explanation-2: -Time moves slower as you get closer to Earth, because, as Einstein posited in his theory of general relativity, the gravity of a large mass, like Earth, warps the space and time around it. Scientists first observed this “time dilation” effect on the cosmic scale, such as when a star passes near a black hole.
Detailed explanation-3: -Clocks run slightly faster at the equator compared to the poles because the earth’s rotation produces a slight bulge at the equator. However, the earth is also rotating faster at the equator. These two effects compensate for each other exactly, causing clocks to actually run at the same rate in both locations.
