That life might be information, as biologists propose, is far more intuitive than the corresponding idea that hard matter is information as well. When we bang a knee against a table leg, it sure doesn’t feel like we knocked into information. But that’s the idea many physicists are formulating. The new science of digitalism says that the universe itself is the ultimate computer — actually the only computer. Weaving together the esoteric teachings of quantum physics with the latest theories in computer science, pioneering digital thinkers are outlining a way of understanding all of physics as a form of computation.
