At one point you said you agreed with me that another observer's reference frame would not lead to a force appearing, but it seems that you again take that view again. So let me ask you the following, in the example with the compasses and the charged car's, or the same experiment with charged tennis balls already described, what if the negatively car's compass has a bomb hooked up to it, so that if it points up the car will explode. >From the cars reference frame no magnetic field in expected and they do not experience an explosion. >From the stationary observers frame let's say the compass points down, no explosion. But from an overtaking cars POV the magnetic field of the car should make the compass point up and explode. Now we have one reality that expects there to be an explosion and no more car, and 2 other reference frames where the cars should still exist. It seems that you would think that this is what should occur? Different permanent fates for each reference frame. That is what would happen if everything happened according to each observers view and expected consequences of their reality being right. Maybe I can see why you are fearful of traps, traps are only in issue if your concept is flawed. John
