random question, but in the course of travelling a supoosed 16k years, how is there no observable flicker or disturbances in the light from there? surely with all the shit floating through that long path there would be flickers and anomalies, instead of it just being constantly visible at times or not visible? also, how does the light have that much power to travel that many years? wouldn't the source of that light be insanely powerful at the start? also how does the light travel in such a straight and uncorrupted path through all the shit in space? in that many years wouldn't the light also differ in speed and get mixed up with other streams of light?
