You can't use the zoom of lens as proof. Research how the curvature and grade of lenses correct contrast, mirage, and so on. This would not be an accurate representation of what would be seen at distance.
That's why we use math to calculate the difference / error %.
If you start with a lens, that's dimensions are known values, you can use those, with other information, like known real distance being observed, and use some basic math to calculate what % error there will be, if any with said lens.
Most likely it would be negligible even at distances of millions of light years.
Regardless, as I said before, basic maths lets us account for error's like this.
Or are we tossing basic mathematics out the window as a way of proving distance/curvature/ etc?
You could do something like this; Error % for X lens = distance viewed through X lens with N dimensions over X distance. Effecting observed light with an error variable of X% to X%.
Our brains do it all the time, on their own, without us even thinking about it, that's how fundamental this type of math isThis post was edited by Ep0ch on Jul 15 2017 08:24am
