Comparing high precision atomic clocks, one flying in a airplane and one on the ground had demonstrated permanent time dilation presumably due to special relativity (speed) and/or general relativity (gravity) .
While similar experiment with a ruler would demonstrate length contraction only when flying due to be measurement and simultaneity but not permanently changed when compared with the ground ruler?
Should I understand that SR does not permanently cause time dilation nor length contraction, while gravity does change length and causes time dilation permanently as per general relativity does? Consequently, gravitation has a real effect on length contraction locally.
Thank you, AlephClo
