Wabbit had an interesting comment in the "Aeon to Zeon" cosmology thread. Here's an excerpt, for more follow the link.
I replied saying I'd start a separate thread.wabbit said:One stray comment here inspired by the zeon and related natural GR unit of length ## \Lambda^{-1/2} ##
...
So the largest possible measurable distance is ## D= \frac{1}{\sqrt{2\pi\Lambda}} ## ~ one zeon.
Or more directly, the maximum area of the boundary of the observable universe, and hence the maximum area of any sphere, is ## A_{max}=\pi D^2=\frac{1}{2\Lambda}## ~ one square zeon.
And the maximum volume of any observable spatial region at fixed comoving time is some constant times ##\Lambda^{-3/2}## ~ one cubic zeon.
This expresses in the flat case the zeon as kind of counterpart to the Planck length, or the inverse of the cosmological constant as the maximum area in units of the minimum area, the Planck area - which I also find interesting from an information viewpoint.
So it seems the zeon (or the zeon squared) may have something fundamental about it :)

This is interesting, and it could be a separate topic

"Smallest measurable angle" call it a "planckian" angle, might be a Planck length or Planck area held out at the "fundamental large distance". Or perhaps the distance scale is a consequence of the limitation on angle measurement instead of the other way round.
I will try to start a separate thread. Maybe it should be in BtSM forum...
