Astrophysical structures from primordial quantum black holes

TL;DR

This paper proposes that the sizes of large astrophysical structures can be explained by quantum properties of primordial black holes, linking quantum field theory to cosmic scale structures.

Contribution

It introduces a novel approach connecting primordial black hole quantization to the characteristic sizes of astrophysical systems, suggesting gravity's role from microscopic to cosmic scales.

Findings

Astrophysical sizes can be derived from primordial black hole quantum properties.

Yukawa corrections in Newtonian potential relate to characteristic interaction lengths.

Quantum field theory underpins the emergence of cosmic structure scales.

Abstract

The characteristic sizes of astrophysical structures, up to the whole observed Universe, can be recovered, in principle, assuming that gravity is the overall interaction assembling systems starting from microscopic scales, whose order of magnitude is ruled by the Planck length and the related Compton wavelength. This result agrees with the absence of screening mechanisms for the gravitational interaction and could be connected to the presence of Yukawa corrections in the Newtonian potential which introduce typical interaction lengths. This result directly comes out from quantization of primordial black holes and then characteristic interaction lengths directly emerge from quantum field theory.
