Correct me if I am wrong, but, if electromagnetism is relative then in a frame where charges have relative motion between the observer, the observer would detect electromagnetic radiation being emitted from the charge, and that to an observer moving alongside the charge at the same speed, no electromagnetic radiation would be detected. So, if what is above is correct then this paradox comes up in my mind. Lets say we have two observers, each is inertial with one standing on the ground and the other moving by in his rocket. Inside the rocket is a van de graaf generator with a strong electrostatic charge and a bomb that is triggered by EM radiation. To the observer on the ground, the charge emits radiation as the rocket ship begins its flight, setting off the bomb and destroying the ship, while the observer in the rocket detects no radiation and believes himself to be safe from the bomb exploding. Can someone clear this up for me?
