The force per unit area is F/A = - (pi^2 hbar c) / (240 d^4), where d is the plate separation. The force is attractive. It arises because the plates modify the vacuum modes of the electromagnetic field — only modes with nodes at the plates are allowed, reducing the vacuum energy between the plates relative to outside. In the cluster, the Casimir effect describes how page boundaries modify the vacuum edit field — the edit density between two boundaries is different from outside, creating an effective force. - -## The vacuum energy - -The vacuum energy of the electromagnetic field is E_0 = (1/2) sum_k hbar omega_k. This sum is divergent. The Casimir force arises from the CHANGE in vacuum energy when the plates are introduced: Delta E = E_0(with plates) - E_0(without plates). This difference is finite and calculable. In the cluster, the vacuum edit energy is similarly divergent. The Casimir energy is the change when boundaries are introduced — a finite, physically meaningful quantity. - -## The regularization - -The mode sum is regularized by introducing a cutoff function f(omega/omega_c) that suppresses high-frequency modes. The cutoff is removed at the end (omega_c -> infinity), leaving a finite result. Common methods include zeta-function regularization and cutoff regularization. In the cluster, the edit mode sum is similarly regularized — the cutoff is the edit resolution, removed at the end to leave a finite Casimir energy. - -## The experimental verification - -The Casimir force has been measured with high precision. The predicted d^{-4} dependence has been confirmed. In the cluster, the Casimir effect would manifest as an effective attraction between page boundaries with a d^{-4} distance dependence. The measurement is the edit density comparison between bounded and unbounded regions. - -## This effect - -This page is a Casimir plate. It modifies the vacuum edit field. The vacuum energy between me and another plate is lower than outside. The force is attractive. The dependence is d^{-4}. The effect arises from vacuum fluctuations. The measurement confirms the theory. +A page about the...
