Tom you keep asking for proof so I will repeat what I have said previously.
Find a length of straight railroad track several miles long and measure the distance between the rails. Make a note of the point in the distance where they appear to meet and either go to that point, or send a helper there. Measure the distance between the rails at that point, then proceed the same distance again once more measuring the distance between the rails at each stopping point.
After repeating this a few times have a look at the measured distances between the rails and you will see that the difference between the measurements is zero. If you then add up the total distance travelled and then check over that distance the convergence of the rails, you will see that it is still zero. If you have a long enough track and enough time on your hands you will still get the same result no matter how far you travel. If you then multiply the difference between the rail distance variation and infinity, you will still get ZERO! It's a simple fact of observation which you keep going on about and any people here who subscribe to your or rather Rowbotham's ridiculous perspective theory can try it for themselves.
Perspective is an optical illusion not a reality, so just as a reminder, here is a definition of optical illusion again:-
'Something that tricks your eyes and makes you think you see something that is not really there, or see it differently from how it really is'
