Reachability places discrete worlds by life tier and by distance from our physics, with edges showing whether you could get to them and how.
Shells puts home at the centre. Each ring is a shell of neighbouring physics
at a given distance dWLD, coloured by what kind of life is possible
there. Ring radius follows the N-sphere law r = R₀·W⅓,
so a ring's area is proportional to how many worldlines it holds.
Pair map puts two constants on the axes with everything else at our values. The white line is the life threshold and the dashed yellow line the marginal threshold. Zoom past the edge of the sampled box and the physics out there is computed on the spot.
Per constant gives one panel per constant. The control that matters is how far the other constants may move. With everything free almost any value is survivable, so the signal is how fast the curve lifts. α and the strong force barely lift at all, while Λ and the mixing angles lift immediately.
Affinity shows how well two constants tolerate being dialed together.
Every cell is an evaluated sample. Scoring runs a multi-pass filter bank over baryon stability, nucleosynthesis, stars, chemistry, cosmology and flavour, plus a consistency pass for the constants that are not independent of each other. The passes combine so that a violated hard barrier drives the score to zero instead of being averaged away.
The bounds are order-of-magnitude anthropic windows in the tradition of Rees, Carr & Rees, Hogan, Tegmark, Adams and Barnes. Eight of the constants show flat panels because nothing in that range moves the result.
Distance is dWLD, a weighted log-decade distance from observed
physics: d = √Σ wᵢ δᵢ² with
δ = log₁₀(X/X₀).
