I don’t mean that any given magnetic field is unchanging, I mean that the principles are stable and well-understood. We never see magnetic fields just randomly change with no reason or else navigation and all kinds of other technologies would be fucked forever.
Explain please?
So you’re hung up on the phrasing “physical forces” not appearing in a textbook?
I’m not making shit up as I go. If you don’t understand something, it isn’t consequently nonsensical.

I mean there’s no way to go from immeasurable to measurable except in scale, and anywhere north of quantum scale, physics has been reliably predictable and measurable. Ghosts’ purported impact is on a scale well above that which is unexplained.
Magnetism is a physical force, like gravity. Measurable and consistent.
Science has never in the history of science reliably shown a single interaction between physical entities and any sort of non-physical force. The only way ghosts could be real is if you redefined the term “ghost” to the point of breaking, like saying that the memory of a person is a ghost.
Plus, it fails the smell test in a million ways. What makes a ghost exist? Why aren’t we positively lousy with ghosts? Are there rules? What would they be and what mechanism is there to both quantify and effect them? Why do ghosts follow the rotation and revolution of the earth but otherwise aren’t physically bound? How can one have any sort of cognition? If a ghost does, how can it perceive anything without intercepting photons or other physical phenomena? If there are ghosts and somehow they have cognition and perception, are we obligated to leave Netflix on when we leave for work?
