1. ### Length contraction or Lorentz Contraction

Yes, I believe so. It requires an outside observer with a lower relative velocity to see light as traversing a distance.
2. ### Length contraction of falling things

How much does a metric really matter when we are discussing light? Light only has 2 spacial dimensions to deal with since distance for it has completely contracted. Keeping it symmetrical then requires a second time dimension at C, making it 2+2 spacetime dimensions. Relativity means symmetry...
