Life in a Random Universe: Sciama's Argument Reconsidered

The Astrophysical Journal
Random sampling in high dimensions has successfully been applied to phenomena as diverse as nuclear resonances, neural networks, and black hole evaporation. Here we revisit an elegant argument by the British physicist Dennis Sciama, who demonstrated that
