Critical density

In Binary Pulse Theory: Critical Density

Same thing, new name

In standard physics

The density at which the universe is spatially flat, 3H²/8πG.

In Binary Pulse Theory

The same density, carried over as the threshold data density at which expansion and matter balance.

The BPT terms behind it

Critical Densityρ⨶

Critical Density is the cosmic density at which, in Binary Pulse Theory, expansion and the balance of matter and geometry meet: the standard critical density of cosmology multiplied by a recursive amplification factor.

Critical Density Relationρ⨶

The Critical Density Relation is the standard cosmological critical density, three times the Hubble constant squared over 8πG, multiplied by a recursive amplification factor that the book says is embedded in cosmic expansion.

Critical Mass Densityρ⨶

Critical Mass Density is the matter share of the standard model's cosmological critical density, carried over by the book as the threshold data density that separates computational substrate regimes.

Also known as

density of the universe · flat universe

The standard physics term is here to help you find your way in; the book itself writes in BPT's own terms. Read them in the lexicon, or start the book at Binary Pulse Theory.
