Preliminary Inconclusive Hint of Evidence Against Optimal Fine Tuning of the Cosmological Constant for Maximizing the Fraction of Baryons Becoming Life

TL;DR

This paper presents a preliminary and inconclusive investigation into whether the cosmological constant is fine-tuned to maximize the emergence of life, exploring multiverse and biophilic explanations.

Contribution

It offers an initial, inconclusive analysis questioning the hypothesis that the cosmological constant is optimized for life formation.

Findings

No strong evidence supporting optimal fine tuning

Hints suggest the cosmological constant may not be set to maximize life

Preliminary results challenge biophilic fine-tuning hypothesis

Abstract

The effective coupling `constants' of physics, especially the cosmological constant, are observed to have highly biophilic values. If this is not a hugely improbable accident, or a consequence of some mysterious logical necessity or of some simple principle of physics, it might be explained as a consequence either of an observership selection principle within a multiverse of many sets of effective coupling constants, or else of some biophilic principle that fine tunes the constants of physics to optimize life. Here a very preliminary inconclusive hint of evidence is presented against the hypothesis of optimal fine tuning of the cosmological constant by a biophilic principle that would maximize the fraction of baryons that form living organisms or observers.
