@ElectroquasistaticMagnetoMan Did you think of a way of proving your trip to spain yet, one that meets your definition of proof?

so why doesn't the moon change size as it goes away from us

if it were close and local it would

but how do you know that, if you don't know what it is

can't say that

are there ever any light sources that behave this way? gonna need an experiment to back up that idea

No i don't think thats true

Where did you hear that

That says that it actually doesn't change size, and ppl mistakenly think it does

@Citizen Z from your citation : The angle that the full Moon subtends at an observer's eye can be measured directly with a theodolite to show that it remains constant as the Moon rises or sinks in the sky. Photographs of the Moon at different elevations also show that its size remains the same.

i copied it
