Gravity warps space-time. Satellites orbiting the earth are actually accelerating towards the earth. So time slows with Gravity also. If you were rotating around the earth much like the satellites in the above quotation say in a spacestation for many years would more time pass on earth that eventually it would become apparent? Eg the astronaught on the above spacestation had a twin brother born 2 mins apart. The astronaught went on the space station aged 18 and stayed on it until he was 68. When he returned would he technically be younger than his twin (by the 7% mentioned earlier due to time dilation) sorry in advance if this is a stupid question I was just looking to test the idea of lightspeed without going into the whole building a warp speed engine (velocity and mass side of things)
