A interesting question came up to my mind, and it's related to the concept of different synchonization methods. If we change the synchronization parameter from 1/2 to some other value, light will have different velocities in opposite directions, which implies that two velocities with opposite directions but same speed value under 1/2 parameter will differ in value while using another synchronization parameter. My question is the following: if we take a rotating object or some other object that is undergoing uniform circular motion, it will change direction at each instant but the speed will be the same. For instance, all points on the equator have the same speed because the radius from the center is same or all of them, but they have different velocities since their direction is different. Under some other synchronization parameter, what will happen with the rotation, because it seems that now a point will also change its speed while changing its directions, since different direction implies diffrent speed under non-standard synchronization. So how will the rotation under 1/2 parameter look like under some other parameter? And this is maybe off-topic, but I think nonetheless it might be related. If we specify the speed of light in opposite direction, let's say on the x-axis, how can we specify its speed in all other directions, since there are infinite number of possible directions, and if light isn't isotropic how can we 'handle' each of them while defining our one-way velocity for each direction?
