The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.

Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

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?
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?
Technically, the moment science would show an interaction between physical entities and something else, that something else would immediately be classified as a physical entity. In a very real sense, the discovery of radioactivity involved physical entities being found to interact with an as-yet unknown, invisible, intangible force.
If ghosts existed, the same would happen as with radioactivity. They would be researched, hypotheses on their nature would be tested, and a scientific theory would arise, and then they would be a part of the "physical world" too. And then all the mystics would be bored with ghosts because they are just incorporeal noospheric echoes of old people, as boring as neurology or biochemistry or stellar fusion.
If a bunch of people were going around saying I got this weird burn on my skin after holding this rock for a while, scientists would have discovered radioactivity a lot sooner.
There are a bunch of people going around claiming to have interacted with ghosts, and we've got bupkis.
That reminds me of this meme:
I found it here after an internet search trying to find it again, but I'm not sure if it is the original source:

The indigenous Australians, the Mirarr people, identified an area in Northern Australia as sickness country which was very coincident with a high concentration of uranium.
They just avoided the area instead of poking it

Aw man. The northern tip of Australia has the cleanest air in the entire world. That data is from pre-y2k
Not sure about that, you might be thinking of the Southern tip. Indonesia often conducts burn offs with a lot of wind blowing smoke over Australia as well as cultural burning conducted by the indigenous in the region. I remember seeing the haze growing up and walking through the burnt country at the start of the dry.
Fucking magnets,
How do they work?

Magnetism is a physical force, like gravity. Measurable and consistent.
Nope.
Explain please?
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.
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"?
One of the definitions of "physical" in the American Heritage Dictionary is:
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.
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.
https://en.wikipedia.org/wiki/Interactionism_(philosophy_of_mind)#Problem_of_causal_interaction
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
So you’re hung up on the phrasing “physical forces” not appearing in a textbook?
I think you could rationally explore ghosts in the “radically redefining” them arena. Ghosts could rationally exist as an artifact of your mind, and saying that is not the same thing as saying they don’t exist. Hallucinations exist. They aren’t real, but they exist. Ghosts could rationally exist in the exactly same way, as processes in our own heads. It’s when you start saying they interact with the world in a way outside people’s heads that you can’t really reconcile.
Except that’s not what we mean when we talk about ghosts. Ghosts are meant to be actual beings with an actual existence, if very different from living beings.
The concept of ghosts exist (as does for all things for which we have words). Some people do believe ghosts exists, and some might have seen ghosts (just like someone actually sees a hallucination). All this doesn’t mean ghosts exist, or else the actual concept of non-existence doesn’t exist - which makes the fallacy evident: if we are to consider that all concepts actually exist (further than just an idea), non-existence has to exist.
