Physics doesn't explain the universe. Computation does – Stephen Wolfram
In a recent talk, Stephen Wolfram argues that computation, rather than traditional physics, is the fundamental principle underlying the universe. He presents his concept of the "ruliad," a vast computational space from which all physical laws and phenomena emerge.
Background
- Stephen Wolfram created the software Mathematica and the answer-engine Wolfram Alpha. Since his 2002 book *A New Kind of Science*, he has argued that simple computational rules (not equations) underlie everything in nature.
- The "Wolfram Physics Project" aims to find a fundamental theory of physics by modeling the universe as a computation running on a "hypergraph" — a network of abstract relations. Space, time, matter, and forces would all emerge from this single computational process.
- Mainstream physics mostly uses equations (like Einstein's or Schrödinger's) to describe reality. Wolfram claims these are just approximations of a deeper, purely computational law — a startlingly different approach that most physicists view skeptically.
- The talk is timely because the rise of AI has made "computation as a worldview" more accessible to general audiences. Wolfram connects his physics project to how large language models work, arguing that computation is the right language for understanding intelligence and the cosmos alike.
