False-vacuum decay and flaws in Frampton's model of the origin of life

TL;DR

The paper critiques Frampton's model of life's origin via false-vacuum decay, highlighting mathematical inconsistencies and physical implausibilities that undermine its conclusions about biogenesis and extraterrestrial life.

Contribution

It identifies fundamental flaws in Frampton's phase transition model for the origin of life, questioning its mathematical validity and physical assumptions.

Findings

The probability calculation is mathematically ill-defined.

The initial configuration assumptions are inconsistent with physical chemistry.

The model's conclusions about biogenesis suppression are unsupported.

Abstract

We briefly review false-vacuum decay and examine a recent proposal by Frampton to model the origin of the first single-celled organism (SCO) as a phase transition between no-life and life vacua. In his calculation the exponent $n$ entering the probability $P_{\rm SCO}\sim 10^{-n}$ has dimensions of inverse time: it is an energy barrier divided by the Planck constant, rather than a dimensionless tunnelling action. The resulting probability is mathematically ill-defined and does not determine a tunnelling rate. Apart from this dimensional issue, the assumed initial configuration, a toroidal structure made of long molecules, and its treatment in empty space are inconsistent with soft-matter physics and with the hot, collisional environment expected for prebiotic chemistry. Consequently, the claimed exponential suppression of biogenesis, and the inference that extraterrestrial life is likely absent, are not supported.
