The distinction between van der Waals force and the Casimir effect is not clear, and both have to do with what might be called quantum atmospheres. I proposed years ago how the Casimir vacuum could be pumped to generate coherent laser-like states. The Josephson-Junction is a soliton result in

I have not been following this. However, your formula for the gravitational force should be F = -GMm/r^2, with the acceleration a = -GM/r^2. It appears you wrote the equation for the velocity of an orbit. LC On Friday, May 6, 2022 at 6:36:38 AM UTC-5 johnk...@gmail.com wrote: > I'm changing
