If two clocks with observers attach to them move away from each with symmetrical acceleration, they will experience symmetrical time dilation, meaning they both see the rate of each other's clocks slow down relative to their own. However, if the acceleration is asymmetrical, the time dilation will be as well (e.g. Clock A will see clock B slow down, and clock B will see clock A speed up). Stop me if I'm wrong here, but I think that's correct. Does this same principal apply to length contraction, or is it always perfectly symmetrical? As always, thank you.
