- TL;DR Summary
- Does the inverse square law hold for luminosity distance at very, very large distances?
Does the inverse square law hold for gravity at very, very small distances?
Quoting from Modern Cosmology by Andrew Liddle on pages 130 and 131: "Let me stress right away that the luminosity distance is not the actual distance to the object, because in the real Universe the inverse square law does not hold. It is broken because the geometry of the Universe need not be flat, and because the Universe is expanding."
In the book "Reality is not what it seems", in the chapter on "Quanta of Space", Carlo Rovelli, states that space must have a minimum dimension and posits that atoms of space must exist. This is part of the proposed Loop Quantum Gravity theory. In the book, it is explained that this assumption is necessary to prevent infinities from arising during normalizations from quantum physics to classical physics.
