We can find advanced aliens not by listening for their radio broadcasts, but by looking for the 'exhaust heat' of their supercomputers.

Thermodynamic Limits of Advanced Intelligence: The SAIERA Framework
SSRN · 6283658
The Takeaway
The SAIERA framework defines the absolute thermodynamic limits of any possible intelligence, predicting the exact infrared signature they would leave in space. It turns the search for E.T. into a heat-seeking mission based on the fundamental laws of energy and computation.
From the abstract
Advanced intelligence, whether biological, artificial, or post-biological, is constrained by strict thermodynamic and informational limits. This paper presents the SAIERA (Self-Amplifying Intelligence for Entropy Regulation and Ascension) framework, a physicsbased model that applies known upper limits of computation, energy use, and entropy management to any system attempting to approach maximal efficiency. Drawing on Landauer's principle, the Bekenstein bound, and Lloyd's computational limit, t
