Equation 22 · Part 4 · A Horizon Is a Toll Booth, Not a Loophole

Symbol H

N⊥[Γ]=2πℏ∫Γ[⟨H(τ)⟩−E0(τ)]dτ.N_\perp[\Gamma] = \frac{2}{\pi\hbar}\int_\Gamma\left[\langle H(\tau)\rangle - E_0(\tau)\right]d\tau.

The passage around this formula

Define the object this paper needs: for a worldline Γ\Gamma traced by a processor, with instantaneous mean energy above its own ground state ⟨\langle H(τ\tau)⟩\rangle - E0(τ)E_0(\tau) measured in the processor’s own comoving rest frame at proper time τ\tau , the cumulative orthogonalization count is N⊥[Γ]=2πℏ∫Γ[⟨H(τ)⟩−E0(τ)]dτN_\perp[\Gamma] = \frac{2}{\pi\hbar}\int_\Gamma\left[\langle H(\tau)\rangle - E_0(\tau)\right]d\tau. N⊥N_\perp[Γ\Gamma] is a real-valued, non-negative functional of a timelike worldline in a fixed background spacetime together with a…
