Yes, of course. Classically speaking you are correct. I should have mentioned that I'm referring to the chiral properties of subatomic particles. My apologies.The "chirality" I mentioned is very simple natural space property. Take a spiral spring or a drill and observe it carefully and you will get it.
Of course Einstein knew about phase and group speeds. He was referring to the group speed of light, which is labeled "c".In the whole course of derivation of SR, Einstein did not mention what light speed c exactly is. Actually, light speed has two different concepts: phase speed and group speed. It's impossible Einstein did not know that. I feel interesting.
