ITU Tier 1+ #19: Astrobiology (Kₐstrobio)

Key Points

This research aims to unify key concepts in astrobiology, specifically habitability, biosignatures, and the Drake equation.
Developed the modular Hamiltonian K_astrobio from integral concepts in astrobiology.
Utilized numerical results from the Drake equation, JWST observations, and upcoming missions like Europa Clipper.
Explored ten falsifiable predictions regarding biosignatures and interstellar habitability.
Introduced K_astrobio as a new operator encompassing various astrobiological factors.
Predicted confirmed biosignature findings by 2030 with a probability of 0.30.
Forecasted Mars sample returns by 2033 with a probability of 0.55.

Abstract

Tier 1+ Pass-1. 5 paper 19 of 45. ITU-derived astrobiology unifying habitability + biosignatures + Drake equation + SETI. Defines Kₐstrobio = -log ρₐstrobio as the operator-algebraic modular Hamiltonian on Hₚlanet ⊗ Hchemistry ⊗ Hbiosignature ⊗ Hₚanspermia ⊗ Hdrake. Kₐstrobio inherits from KQG via the CLPW 2023 type II crossed-product specialised to this scale. Numerical results.
