Even with those uncertainties, standard candles are usable to a strong degree. How accurate are your FE measurements and what methods do you use with those? How far away is the 'dome'? How do you measure that distance? Why can't I see coastal Lisbon, Portugal from coastal New York city with a telescope? Where are these answers?
I'm not sure how far away the dome is, give me a trillion dollars and I might be able to find out.
Have you tried to see portugal from new york? Where are the videos of that? I can't find any.
I imagine if anyone actually tried, the refraction of light off the atmosphere would make it hard to see. (Same reason the sky is blue and we can't see stars during the day.)
Maybe some kind of special infrared camera with an amazing zoom lens could do it...
