... Morley looked and looked, and decided it wasn’t there. How do waves travel??? Electricity and magnetism are “relative”: Whether charges move or not depends on which frame we use… This was how Einstein began thinking about his “theory of special relativity”… We’ll leave that theory for later…maybe. ...
