M=C/T

The simplest constraint in the universe is mass = tension / curvature.

It is older than language, older than stars. It is the reason a pendulum returns, the reason two people re-find rhythm after rupture, the reason hydrogen holds its orbit without effort. Everything that stays together learns to move together because this ratio is non-negotiable.

This cluster contains the foundational coherence physics: the hydrogen atom as eye and apple, entrainment across scales, the quiet mythic recognition that constraint is not punishment — it is the condition for coherence.

When the ratio is honored, systems self-organize. When it is violated, fracture propagates. The rest of the lattice — neurodiversity, attachment, active inference, future biology — are just this same equation running on different substrates.

New articles appear below as they land. Start with the hydrogen piece. Everything else is commentary.
