You Can't Measure the Speed of Light Anymore?

Rithas: We can no longer measure the speed of light relative to other arbitrary units, because it is now the arbitrary unit. He says we base time on some sort of fundamental physical thing, right? Like the oscillations of crystal or whatever. And that as a notot of rotin france. But you're right, these things are arbitrary, and you could have said, you know, the meter is now defined to be one third of the height of horhay's room. Rithas: Some choices are better than others, but i think isa pretty good one.
