In physics and cosmology, digital physics is a collection of theoretical perspectives based on the premise that the universe is, at heart, describable by information, and is therefore computable. Therefore, the universe can be conceived of as either the output of a computer program, a vast, digital computation device, or mathematically isomorphic to such a device.
Digital physics is grounded in one or more of the following hypotheses; listed in order of decreasing strength. The universe, or reality:
- is essentially informational (although not every informational ontology needs to be digital)
- is essentially computable
- can be described digitally
- is in essence digital
- is itself a computer
- is the output of a simulated reality exercise
Famous quotes containing the word physics:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
