Is the Whole Universe a Computer™?

Published Jan 5, 2025, 12:02 AM

"Is the whole universe a computer?", ask Jack Copeland, Mark Sprevak, and Oron Shagrir in chapter 41 of the book The Turing Guide. They split this question in two, first asking whether the universe itself is a computer, then whether the universe could even be computed. These are lofty, unanswerable questions, sure, but they encroach on our territory — philosophy, automata, nonsense. So, in our usual reverent style and with attentive pacing, the three of us explore the paper, the questions, the answers they choose to highlight, and even share a few perfectly reasonable answers of our own.
