the walk. take any number, divide 1 by it, add 1, repeat. the set point is where the answer equals the input: x = 1 + 1/x, which solves to 1.6180339887…, the golden ratio. near it the walk undershoots and overshoots by a factor of 0.382 each time: a damped swing, the shape of any good regulator. the stops from 1 are ratios of neighbouring Fibonacci numbers (2/1, 3/2, 5/3, 8/5, 13/8 …). your "1.6.5" reads right as 8 ÷ 5 = 1.6, step five. the swing shrinks 2.618× every step, so 84 steps take it from 1 to within 1.6 × 10⁻³⁵ of the set point, the Planck length: your "walk it to plank 0.0.0". the chart past 10⁻¹⁵ is drawn from the exact Fibonacci formula, since ordinary computer numbers run out of digits there. almost every start comes home. any positive start does. −1 passes through 0 and then 1/0 (infinity), which the next step turns back into 1. the one start that never comes home is the other fixed point, −0.618, but only if it's exact to infinite digits. nudge it by the last digit a computer holds and it drifts away, then settles at 1.618 like the rest. the chart shows that too. gen 3. the first stars (population III, no metals) lit a few hundred million years in. the second generation (population II) is the old halo and globular clusters, 12–13 billion years old. the Sun belongs to the third (population I), rich in metals from both earlier rounds. that's why there's gold here at all. the Sun is 4.6 billion years into a roughly 10-billion-year life: halfway round. 13.2 billion years ago is 0.6 billion after the start, when the first galaxies were assembling. "third black hole" and (16 − 6) ÷ 2 = 5 as generation totals are yours: the arithmetic is LIT, the meaning is AMBER.
