A friend and I are arguing over ghosts.

I think it’s akin to astrology, homeopathy and palm reading. He says there’s “convincing “ evidence for its existence. He also took up company time to make a meme to illustrate our relative positions. (See image)

(To be fair, I’m also on the clock right now)

What do you think?

Magnetism is a physical force, like gravity. Measurable and consistent.

    You keep saying "physical force"...

    That's not a real term in physics.

    The only possible explanation, is you mean any force that is already explained by physics, is that what you mean?

    Because that would be the same as insisting we know everything, which no one who knows anything about physics would ever try to claim.

    So...

    What exactly do you mean when you keep saying "physical forces"?

    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.

    Why do you say ghosts' purported impact is on a scale above that which is unexplained?

    Quantum fields impact the universe on a scale above their own. It's entirely possible that the explanation for ghosts is on the quantum scale or smaller, and the observable effects are just that: effects of a much subtler phenomenon.

    Yes, quantum scale has macro effect, but the macro scale is predictable and rigidly causal, negating any meaningful quantum scale interactional impact. A macro causation effected via quantum interactions is a de facto macro interaction.

    None of what you've said is n this thread makes any logical sense...

    Which would be fine cuz it's about ghosts, but you keep acting like physics backs up your wild statements and made up vocabulary...

    I’m not making shit up as I go. If you don’t understand something, it isn’t consequently nonsensical.

    What exactly do you mean when you keep saying “physical forces”?

    The phrase doesn't appear once in your link. Or anywhere else in reference to physics...

    You 100% made that up, and at this point I don't really care why

    The earth's magnetic field is fluid and changing, magnetism is affected by electrical current or heat.

    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.
