Does Time Cause Gravity?

Season 7 Episode 9

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 does gravity causes the flow of time to slow down? In a sense, it’s no. Gravity does NOT warp the flow of time. It’s the other way around the warping of time causes gravity.
