What is the universe computing? As far as we can tell, it is not producing a single answer to a single question…. Instead the universe is computing itself. Powered by Standard Model software, the universe computes quantum fields, chemicals, bacteria, human beings, stars, and galaxies. As it computes, it maps out its own spacetime geometry to the ultimate precision allowed by the laws of physics. Computation is existence. —SETH LLOYD AND Y. JACK NG62
