Drake Equation for the Multiverse: From the String Landscape to Complex Life

TL;DR

This paper refines the application of the Drake Equation to multiverse scenarios, emphasizing that conditions for primitive life do not necessarily lead to complex or intelligent life, and proposes renaming the anthropic principle as the prebiotic principle.

Contribution

It introduces a framework distinguishing conditions for primitive life from those for complex life within multiverse models, challenging traditional anthropic reasoning.

Findings

Selection criteria for life are insufficient for complex life emergence.

Transition to complex life requires additional planetary conditions.

Proposes renaming the anthropic principle to prebiotic principle.

Abstract

It is argued that selection criteria usually referred to as "anthropic conditions" for the existence of intelligent (typical) observers widely adopted in cosmology amount only to preconditions for primitive life. The existence of life does not imply in the existence of intelligent life. On the contrary, the transition from single-celled to complex, multi-cellular organisms is far from trivial, requiring stringent additional conditions on planetary platforms. An attempt is made to disentangle the necessary steps leading from a selection of universes out of a hypothetical multiverse to the existence of life and of complex life. It is suggested that what is currently called the "anthropic principle" should instead be named the "prebiotic principle."
