It from bit. It’s an unorthodox theory, which starts with the assumption that information is at the root of all existence. When we look at the moon, a galaxy, or an atom, their essence, he claims, is in the information stored within them. But this information sprang into existence when the universe observed itself. He draws a circular diagram, representing the history of the universe. At the beginning of the universe, it sprang into being because it was observed. This means that “it” (matter in the universe) sprang into existence when information (“bit”) of the universe was observed. He calls this the “participatory universe”—the idea that the universe adapts to us in the same way that we adapt to the universe, that our very presence makes the universe possible.
