About this episode

The episode discusses the concept of the ruliad and its implications for physics, mathematics, and the possibility of alien life.

The ruliad is every possible computation. What could you possibly say about such an enormous, all-encompassing object? Well, that’s where we come in. Particular observers sample the ruliad in particular ways. Observers like us sample the ruliad in ways that give rise to physics as we know it. Ruliad + observer = physics. In this excerpt from my conversation with Stephen Wolfram, he explores how physics, mathematics and biology all arise from this same enormous, all-encompassing object, the ruliad. He gets to aliens, too, asking such provocative questions as how far from us in rulial space are the nearest aliens? — Stephen Wolfram Stephen Wolfram The Wolfram Physics Project Wolfram Institute Wolfram Institute Community Discord References Ruliad definition Ruliad article Second Law of Thermodynamics article Second Law of Thermodynamics history Metamathematics article Metamathematics book Biological evolution article Biological evolution follow-up Computational irreducibility — The Last Theory is hosted by Mark Jeffery founder of Open Web Mind I release The Last Theory as a video too!
