Symbol t_P

The passage around this formula

…Push the clock to that boundary — as large as coherence allows, no larger — and the two prices combine into a floor whose shape is set entirely by the constants already on the table: $\mathcal{A}_{\min}(\tau) \gtrsim \chi\left(\frac{t_P}{\tau}\right)^{2}$. one Planck time, $t_P$, set against however long a lab is willing to average, squared, times a geometry factor χ the paper’s appendix fixes and does not pretend is order-unity by assumption. The exponent is the point, not the coefficient: it is what makes this a floor derived from an accounting of two established…
