It is deeply connected to the concept of information theory, particularly the idea that the universe's fundamental building blocks might be bits of information rather than traditional particles or fields. 94: 322:, all of which are central to current physical theories.

Despite these challenges, covariant discrete theories can be formulated that preserve the aforementioned symmetries.
