Length contraction of falling things

 Quote by harrylin Well, what can I say?

When you are sawing a log, the frequency of the vibrations changes if the speed of the saw changes. If the log does its own motion that also changes the frequency, if the saw contracts or expands that changes the frequency too.

But we can calculate the frequency in a simple way:

number of saw teeth / duration of one sawing stroke

Well, once you learn some GR then please come back and try your derivation again.

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, right?

Since the metric is what determines which paths are null geodesics, it matters a lot. The rest of your post is really nonsense.
