The fate of black hole singularities and the parameters of the standard models of particle physics and cosmology
Lee Smolin

TL;DR
This paper proposes a cosmological model where parameters of particle physics and cosmology are selected through a natural selection process driven by black hole singularity removal, predicting that small parameter changes reduce black hole production.
Contribution
It introduces a novel scenario linking black hole singularities and parameter selection, suggesting parameters are optimized for black hole production and providing testable astrophysical predictions.
Findings
Small parameter changes decrease black hole production in spiral galaxies.
Predicted cosmological timescale aligns with galaxy star formation periods.
Model supports observed matter density parameter Ω ≈ 0.1-0.2.
Abstract
A cosmological scenario which explains the values of the parameters of the standard models of elementary particle physics and cosmology is discussed. In this scenario these parameters are set by a process analogous to natural selection which follows naturally from the assumption that the singularities in black holes are removed by quantum effects leading to the creation of new expanding regions of the universe. The suggestion of J. A. Wheeler that the parameters change randomly at such events leads naturally to the conjecture that the parameters have been selected for values that extremize the production of black holes. This leads directly to a prediction, which is that small changes in any of the parameters should lead to a decrease in the number of black holes produced by the universe. On plausible astrophysical assumptions it is found that changes in many of the parameters do lead to…
