Okay I am new to relativity. I have been reading some books. Let me see if I understand this correctly. Consider the following scenario. There are 2 observers or inertial fames. They are moving apart at a constant velocity. Each ovserver can consider itself at rest relative to the other. Observers move through spacetime at the speed of light. In each relative frame the following can be considered true. Motion is converted from the time dimension into space through adjacent frames of symmetry, so that each observer can consider the other as falling over a sort of horizon as frames transate. These distortions are from the perspective of each observer a sort of fleshing out of an underlying symmetry in which mirror images or probability zones can be considered equal even though they are kind of negative opposite. Sorry if I am not very coherent, but am I on the right track?
