As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Which raises a question familiar to aficionados of The Matrix—might life and the world as we know it be a simulation on a super advanced computer? “Digital physicists” have developed this idea well beyond the sci-fi possibilities, suggesting a new scientific paradigm in which computation is not just a tool for approximating reality, but is also the basis of reality itself. In place of elementary particles, think bits; in place of fundamental laws of physics, think computer algorithms. But is this a viable approach? Is the universe the ultimate computer running some grand cosmic code? A discussion among the brightest minds in digital physics to explore math, computer science, theories of consciousness, the origin of life, and free will—and delve into a world of information that may underlie everything.

Edward Fredkin’s computer career started in 1956 when the Air Force assigned him to work at MIT’s Lincoln Laboratories. In 1968 he started at MIT as a full professor. From 1971 to 1974 he was the Director of CSAIL and he spent a year at Caltech as a Fairchild Distinguished Scholar, working with Richard Feynman.Read More
