I was wondering how is our perception created according to relativity, since what we perceive depends on the perspective we have on the space-time around us. If two events are simultaneous in our frame by deduction from our perception we will realize that they are, and that the causal process and the propagation of light led to our inital perception. But what happens when the same variables are 'viewed' from another frame. For instance two events previously menitoned aren't simultaneous in some other frame, so basically the causal process that leads to a different description where space like separated events don't happen at the same time. For example, if two events are simultaneous w r to one observer and he perceives them like that, how would some other observer in a different frame describe the process of those events (which are not simultaneous) propagating by light to his eye, than to his nerves and brain and finally creating qualia which corresponds to the view from the initial frame? I hope you understand my question. Regards, Johnny.
