If you were a few thousand kilometers tall, would the cells in your feet age at a different rate than those in your head?

- tsimionescu 5y agoIf you're on Earth or in general near a strong gravitational field, yes, because your feet experience a different acceleration than your head (marginally, we're probably talking like a second every decade or less - atomic clocks on GPS satellites at 20k km from the surface run faster than atomic clocks on the surface by ~40microseconds/day, so that would accumulate to ~3.5s/decade). If you're floating around in the void, no, everything is stationary relative to each other, and experiencing the same acceleration, so no real difference. There would still be some small difference between the cells closer to your center of mass than the ones farther away, because you also have your own gravitational field, but it would be so weak it would almost not matter at all.
