Critique of a Model for the Origin of Life
Analysis
This paper critiques a model by Frampton that attempts to explain the origin of life using false-vacuum decay. The authors point out several flaws in the model, including a dimensional inconsistency in the probability calculation and unrealistic assumptions about the initial conditions and environment. The paper argues that the model's conclusions about the improbability of biogenesis and the absence of extraterrestrial life are not supported.
Key Takeaways
- •The paper identifies a dimensional error in Frampton's model.
- •The model's assumptions about initial conditions are inconsistent with established physics.
- •The model's conclusions about the improbability of life are not supported.

“The exponent $n$ entering the probability $P_{ m SCO}\sim 10^{-n}$ has dimensions of inverse time: it is an energy barrier divided by the Planck constant, rather than a dimensionless tunnelling action.”
