I think this makes a lot of sense:
this seems more like metaphysics, or philosophy than actual science, this would be more appropiate in that discussion. you odnt want to mix religion into science.
It would be science, because I'm asking if something that isn't physical in origin exists.
It sounds like you're trying to use the wrong tool, though. Science is a great system for learning about the observable universe, but less so for other things. To put it another way, science is great for telling you how, philosophy is great for exploring why.
But aren't most philosophers Physicalists who just say "Listen to the science"
No reason to doubt it.
It doesn't mean that there's no soul, god, or after life, just none that we can prove in any meaningful way.
It also depends how you define physical matter.
If it's something you cam touch, then there definitely is, starting with neutrinos.
If you mean particles we know about, can describe and sort of understand, then there's dark matter, which is probably particles we don't know yet, but have several candidates we didn't manage to confirm or disprove yet. They can only interact by gravitational (and perhaps weak?) force.
If you mean something we know at least something solid about, there's dark energy, which isn't absolutely 100% certain that it exists, but is widely accepted.
If you mean something physics doesn't detect and try to explain, then obviously not.
How is Dark Matter non-physical?
In the sense that it isn't particles we know about, can describe and sort of understand, as I wrote. Plus you can't touch it. You didn't say what you mean by physical, so I tried 4 different definitions I thought you might mean.
No free will would depend on everything being predeterminable. Which isn't. Look up quantum physics, if you missed it in school.
Which evolves deterministically undisturbed, or with complete randomness if you pick an interpretation that accepts the literal existence of measurement. Free will is very specifically neither of those.
