Statistical Evidence Against Simple Forms of Wavefunction Collapse

TL;DR

The paper presents statistical evidence challenging simple wavefunction collapse models by arguing that the observed fine-tuned physical constants are unlikely under such models if the universe's initial state is a multiverse superposition.

Contribution

It introduces a novel argument against simple collapse models based on the statistical improbability of observed physical constants.

Findings

Observed coupling constants are statistically unlikely under simple collapse assumptions.

The argument suggests the need for more complex or different collapse mechanisms.

Supports the view that wavefunction collapse models must account for fine-tuning evidence.

Abstract

If the initial quantum state of the universe is a multiverse superposition over many different sets of values of the effective coupling "constants" of physics, and if this quantum state collapses to an eigenstate of the set of coupling "constants" with a probability purely proportional to the absolute square of the amplitude (with no additional factor for something like life or consciousness), then one should not expect that the coupling `constants' would be so biophilic as they are observed to be. Therefore, the observed biophilic values (apparent fine tuning) of the coupling "constants" is statistical evidence against such simple forms of wavefunction collapse.
