This becomes a question about the resolution of the human eye, not one of general physical principles. If you cared about how close something has to be for our eye to make out its dimensions accurately, you should have asked a question about peoples eyes from the very start. Posing the question as two light-emitting objects without eyes in makes it sound like a question of the fundamental properties of light. Which is it?

As far as I can tell this is fundamental problem with all of the "questions" TheBox asks. There seems to be a complete inability to comprehend the difference between the fundamental properties of something and observation dependent issues that can be traced back to the equipment being used to measure a thing.

It's both, it's observation and relativity.


When an object moves away from us it relatively visual contracts to the eye, the light that we did see in 3 dimensional form of the object becomes 0 dimensional over a distance away ,   relative to the observation and the object the light between eye and object collapses from 3d into a 1d singularity whole, a thread with zero diameter.
This is true no matter which direction you look into space.
When you look at the black background of space, it is not an edge or an expanding space, it is simply there is nothing in range to see, the two reasons are the inverse square law and the relative observation contraction of objects., showing space to be n-dimensional.

n to n is a singularity of zero, 1 to 1 is a length and relative visual dimension of light.

The quanta visual tunnel collapses to n.

added- sorry


Each individual Galaxy must be an individual singularity , (singularity your definition).?


Maybe even every single particle?


Could there be a singularity single particle(s)?

When an object moves away from us it relatively visual contracts to the eye, the light that we did see in 3 dimensional form of the object becomes 0 dimensional over a distance away..., a thread with zero diameter. ... there is nothing in range to see

When an object is close, you can perceive it as a 3-dimensional object because of binocular vision. But this only works out to about 5m, after which it is effectively 2-dimensional (although, if it is a familiar object, your brain can fill in the third dimension).
See: https://en.wikipedia.org/wiki/Stereopsis

The angular resolution of the human eye is about 0.02 degrees. When an object subtends less than this angle, it effectively decreases to a point. It appears zero-dimensional.
See: https://en.wikipedia.org/wiki/Naked_eye#Basic_accuracies

But humans can see things that are farther than this. The star Sirius subtends an angle of 0.006 seconds = 0.0001 minutes = 0.000002 degrees. According to this theory, it should be zero-dimensional and invisible; and yet it is easily visible as one of the brightest stars in the night sky.

Thank you for the links which learnt me some new phrases/words. 


What I am asking you , is that when an object moves away from you it becomes an x,y plane and 2d, the greater the radius the more x,y visual contracts and the angular diameter contracts.   At point ? the X,Y plane will visually contract to a zero point source and 0 x,y   .     The angular diameter collapsing to a 0 diameter ''thread'' leaving the observer looking into n-dimensional space?


0 degrees←→0 degrees in any direction, a Quanta whole of light passing through space.


The only perfectly flat thing in the Universe is light passing through space,   surfaces are never perfectly flat because of the electron shell is a sphere.

You said infinite, surely my ideas have premise to argue with the teacher.

In these last few posts, I think you have drifted off towards infinity and beyond...

Not really , it is what I observe with my eye when I look next to a star in the relative ''empty'' space .  My symbol in the last diagram is correct?  it means angular diameter from the links that were provided


Visual angle and angular diameter of an object, by radius increase from the observer,  visually contracting the X,Y plane 2d  view of the object to a 0 visual angle and 0 angular diameter.  The light between observer and object becoming L₀ that is equal to L_n and extends into oblivion.


added VL₀=VL_n  (that's visual length)


λ₀  =  λ_n

I have 'zoomed in'' on an area next too the furthest away observed point source, I have measured it by calculations in my  mind, can you please confirm your measurement of the same Length please?

added- I have now panned my imagination telescope to the left observing the furthest away point source and now I have a different measurement
