Digital information is the fundamental block of all reality

Reality as a pattern of information

In this speculative picture, the basic ingredients of the universe are not tiny bits of matter but distinctions and relationships: which state a system is in, how it changes, and how it connects to other systems. A “bit” is the simplest unit of information, distinguishing between two possibilities, such as on and off. The proposal is that physical things may arise from vast networks of such distinctions rather than existing as independent building blocks.

How information could become a world

A bit alone does not make a sunset. The idea requires rules governing how bits relate and change. If those rules produce stable patterns, those patterns could correspond to familiar physical features: particles, forces, space, and time. On this account, matter would be less like the underlying substance and more like a durable pattern in an immense informational process.

The computation metaphor helps make the picture imaginable. A sunset depends on light interacting with air, clouds, and an observer; those interactions unfold according to physical laws. Calling the whole process a computation suggests that its outcome follows from information and rules. It does not necessarily mean the universe is running on a computer built by someone, or that pixels and software literally lie beneath the sky.

A proposal, not a settled result

Physicists can use information to describe systems and predict what measurements may show. The stronger claim—that information is the ultimate foundation of physical reality—is a philosophical and scientific speculation, not an established finding. A key challenge is explaining precisely how familiar laws and objects emerge from information, and how that account can be tested against other explanations.

If the view is right, the world’s richness would come not from a separate ingredient for every thing, but from the patterns formed as fundamental distinctions interact. In that sense, a sunset would be both a physical event and the visible consequence of an underlying informational story.
