apparently this "method is valid out to 30,000 light years...only!

even the above seems suspect 30k ly is an awful lot of space using trig type method. I dont think the instruments used can employ such resolution - it starts to get silly.

in fact the guy who was talking bollocks earlier is now making sense... the age of the light coming from these stars and the fact that you are looking at a stationary object... it makes no sense to quantify using distance/time - itself an illusion.

by the way I absolutely know nothing of what I am talking about - I'm only making assumptions on what I have read these last few minutes...
