Velocity = distance x frequency
You f**king idiot; my point is, that if the DISTANCE is incorrect, then the VELOCITY will be incorrect.
& as a telescope can NOT tell me the DISTANCE, then I can NOT know whether what I am looking at is truly flying at the claimed altitude of the ISS or is a
SLOWER object flying at a
LOWER distance.
Like a pimped-out spy-plane, for example...
Wtf is WRONG with you, retard?
Oh; I forgot - you're a Troll!
So STFU.
& LOL!!!
