Hi everybody, I have a question concerning length contraction/time dilation. I read about how time dilation is calculated using transverse motion and how length contraction is calculated using longtitudinal motion in order to preserve lightspeed and it got me thinking: why not use length contraction for both types of motion. So instead of dilating time for transverse motion, why not contract the length by the same amount you contract it in the longtitudinal directon. I know this may sound weird and I'm not sure if I'm formulating it very clear, but I was thinking about it and I couldn't figure out why we need TD and LC to preserve lightspeed. Can you tell me if there's something I'm missing or that maybe I'm looking at it the wrong way?
