# Casimir effect

The estimated total aetheric pressure within the gap between the plane objects, according to the particle model (see "Mass and inertia"), is: $P=\rho v^2=\frac{Ke^2}{16\pi^2\varepsilon_0}\frac{1}{d^4}$ $$K$$ is a dimensionless coefficient, which depends on the particles concentration and their aetheric vortices geometry;
$$e$$ is the elementary charge;
$$\varepsilon_0$$ is the vacuum permittivity;
$$d$$ is a gap size.
According to the quantum theory, this pressure weirdly does not depend on the material properties: $P=\frac{hc\pi}{480}\frac{1}{d^4}$ The experimental measurements are technically difficult and, therefore, questionable.
