Why this formula appears here
A bound built from a quantum price that improves with more atoms and energy, set against a relativistic rent that gets cheaper the larger the clock, does something a naive “smaller is always better” or “bigger is always better” intuition would not predict: it selects a best size. The relativistic rent falls as 1 over R, so a larger clock pays less rent per unit of energy fluctuation. But a clock cannot be made arbitrarily large without breaking its own coherence — the paper takes Salecker and Wigner’s clock-size ingredient and repurposes it as a constraint rather than the punchline it was built to be: a clock’s different parts have to stay in synchronized causal contact within a single tick,…
