Percolation Of ‘Civilisation’ In A Homogeneous Isotropic Universe
In this work, we consider the spread of a ‘civilisation’ in an idealised homogeneous isotropic universe where all the planets of interest are habitable.

Non-Living Intelligence: Cracking The Code For Materials That Can Learn
It’s easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors.
![[L] The x-axis is the Sagan’s parameter of the Kardashev civilization Type K. The y-axis is the mass of PBH in solar mass for a fraction fPBH = 0.01. The colour-bar of the contours shows the quantity Kachieved/K − 1, which Kachieved is the amount of civilization parameter achieved by PBHs.
