The Great Simulation

Twenty-odd constants tuned to one part in 10¹²⁰. An absolute speed limit. A minimum scale below which the world stops answering. A universal digital code at the heart of every living thing. Science calls all of this coincidence; this book argues they are parameters.

Drawing on Bostrom, Wheeler, Hoyle, Weinberg and Penrose, Cristian Cruzat Valdes builds a case in fifteen pieces of evidence and answers the ten most serious objections one by one. The conclusion is uncomfortable and hard to evade: every argument exists for asserting that we are inside a simulation, and none exists that rules it out.
