We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow of time to slow down. And I’m not going to explain it now – because in a sense it’s not true. Gravity does NOT warp the flow of time. It’s the other way around – the warping of time causes gravity.
