Hi all. Suppose we have two objects A and B, and suppose we tie a rope R to the objects with the rope R's two edges hooked to a pole or hook on each of the objects. The rope is loosely connected to the hooks on such a way that as objects will move away from each other, then as the rope will get stretched to the maximum the rope will go off hook as a result of the farther motion. Now as par classical physics when one of the objects A will move away and the rope will get stretched to its maximum, than the rope will go off A's hook but not off B's hook. This is due to the fact that since A is the one in motion, and as such the tension to rope is applied at A, and as such the rope is immediately caused to get off hook. But while the tension is traveling towards B, the rope is no longer tied to A which result in the rope tension being released and as such the rope is not going off hook at B. This should be true no difference whether A is in accelerated motion or in linear motion, and in either case the rope will go off hook the object in motion and not at the object in rest. But according to relativity A might claim to be at rest and B in motion, and according to A then the rope should go off at B. But clearly only one of them can be right (note that if the rope goes off hook at both then both must be wrong!), so clearly one of them will get disproved. So how does this fit with relativity?
