We have just looked for how light could have the same speed for the fixed observer and for the moving observer: the deepening of this point revealed to us that a system S’, resulting from the splitting of a system … Read More

More generally, let us still call S a system immobile in the ether, and S’ a double of this system, which first coincided with it and then detaches itself in a straight line with the speed v. While S’ contracts … Read More
