Again, I think you’re replying to the wrong person. I never disagreed with any of this. I literally learned all of this years ago. I appreciate your attempt to educate, but I’m unclear on its purpose. The dude claimed that the speed of light is defined based on the meter, and that that makes it a tautology. That is simply, provably false. Then the dude tried to move the goalposts. Never did I say that our measurements are anything less than relative. Never did I suggest that our derived units are not based on fundamental constants the nature of which can be only guessed at. Now, you’ve said that the statement I made didn’t tell the dude “how to make use of” dimensionless units, which is a complete non sequitur. If you feel that that lecture is an important one when a dude demonstrates a fundamental misunderstanding of what c even is, that’s your own affair, and I invite you to give this lecture a few comment levels up to the guy who thinks that c is defined based on the meter.
