magnO, I see that you are pursuing a theory as to what is causing the Earth expansion.
We have a section on this Forum called “User Diaries†where users can post projects or ideas that they are working on.
It would be helpful for everyone if you posted your idea or theory there. It could help everyone here to understand what you are trying to accomplish and maybe even suggest a better way to test the theory.
Could there be another way to test it besides trying to determine the behavior of one spherical magnet inside another?
Your question has generated substantial interest here, so if they can see what your ultimate goal is, there is a possibility that someone could come up with a more appropriate way to test your theory.
I find the idea of Earth expansion interesting because it is related to one of my areas of research. For years I have been studying the possibility that the Big Bang is not a Bang but a Big Whoosh, as the remnant of stars, pulsars, quasars, and whole galaxies, in the form of quarks, gluons, neutrinos, etc…, pass through the center of a Black Hole at Planck temperature and at speeds billions or trillions of times faster than the speed of light.
This could be possible if what we call the Universe is in the shape of a Torus similar to this:
If the Universe is shaped like this, there could be billions of other Universes, some bigger and some smaller than ours.
And what if all these Universes are part of a larger Torus with an incomprehensible size Black hole at its center? Oh boy, I better stop there…
