:::::::::::: The Mercury and binary pulsar observations were used to support the gravity theory, and relativity remains the most accurate explanation. Andy, you asked about electromagnetism, not gravity. There is no way to understand electromagnetism without relativity, as far as I know. The Kaufmann experiments were supposed to disprove relativity. More precise experiments were consistent with relativity, as with all the other electromagnetic experiments. Just turn on an old-style TV set with a tube. How do you think that those pixels get lit up?
