The Dependency Chains

The successful debut of human life depended on an unimaginably long cascade of prior conditions—a hierarchy of interlocking dependencies stretching from the behaviour and properties of minuscule sub-atomic particles to the those of galaxies and their relationship to the vast cosmic web.

No law or principle in the foundational sciences stands alone in complete isolation; every layer of reality is scaffolded by countless laws already functioning in synchrony.

The dependency chain that begins with subatomic particles and forces and extends through atoms, stars, heavy element formation, planetary architecture, and finally the arrival and maintenance of living systems, reveals a universe in which complexity emerges, not from a series of fortuitous incidents but as a consequence of deep structured interdependencies.

Dependency chain of items, forces and laws, from the minuscule to the gigantic.

This cosmic lattice mirrors the biological one: just as sexual reproduction requires a densely entangled web of mutually contingent processes (see the article ‘Daddy, where do babies come from?’), the very existence of matter, chemistry, stars, and habitable worlds requires an intricate network of finely balanced prerequisites to sustain their coherence.

Together, these chains form a comprehensive answer to the enigmatic puzzle explored in The Code at the Dawn of Life: Life is manifestly not the product of fortuitous isolated events, but the culmination of a vast, coordinated symphony of precise conditions that had to be in place long before biology ever began, and that therefore occurred before any possibility that evolution, mutation, and natural selection could even get started.

Below is a somewhat technical summary of some of these links, each of which is essential for the complete picture of the arrival and maintenance of comfortable life:

A galaxy is only meaningful if stars exist,

which depend on finely-tuned gravitational collapse within molecular clouds,
which depend on atoms capable of radiating away heat,
which depend on stable nuclei forged in earlier generations of stars,
which depend on protons and neutrons bound in the atomic nucleus,
which depend on quarks held together by gluons,
which depend on the strong nuclear force operating at femtometre scales,
which depends on quantum chromodynamics and the behaviour of gauge bosons,
which depend on the deeper structure of quantum fields,
which depend on the very fabric of spacetime that allows fields to exist at all.

Stars depend on nuclear fusion,

which depends on quantum-tunnelling overcoming Coulomb barriers,
which depends on precise proton masses and charge values,
which depend on the balance of fundamental constants,
which depend on the conditions set in the first seconds following the birth of the universe.

Life essential heavy elements depend on supernovae and neutron star mergers,

which depend on massive stars eventually exhausting their fuel,
which depend on stellar nucleosynthesis cycles,
which depend on long term gravitational stability,
which depends on dark matter scaffolding around galaxies,
which depends on non baryonic particles interacting only weakly with light,
which depends on the primordial density fluctuations seeded by the very energy of spacetime.

Planets depend on proto-planetary discs,

which depend on angular momentum conservation during star formation,
which depends on turbulence and magnetic fields in collapsing clouds,
which depend on charged particles and plasma behaviour,
which depend on electromagnetic interactions between particles.

Life depends on planets with stable environments,

which depend on long lived stars,
which depend on delicate balances between gravity, pressure, and fusion,
which depend on the interplay of fundamental forces.

(See also the many additional attributes of our earth, moon, sun and solar system, the fine balances of which are required for the support of comfortable life, in the section 'Planets - Nurseries for Life' on the 'Planning' page.)

Atoms depend on electrons bound by electromagnetism,

which depends on photons mediating the electromagnetic force,
which arise from the U(1) gauge symmetry that governs how electric charge interacts,
whose topology determines charge quantisation,
which reflects the deeper structure of gauge symmetries,
which are shaped by electroweak symmetry breaking via the Higgs field,
which depends on vacuum energy and the stability conditions of the universe.

And the cosmic web—the vast architecture of galaxies, filaments and voids—depends on gravitational amplification of tiny quantum fluctuations,

which depend on cosmic forces stretching microscopic irregularities to universal scales,
which depends on physics operating at energies far beyond current experiments,
which depends on the finely-balanced properties manifest in spacetime, fields, forces, and particles in the first place.
