Supernatural, to my knowledge refers to some force beyond scientific understanding or the laws of nature.
So it seems to indicate that even if it were a phenomenon that were observed, it is not possibly to measure with current instrument, and baffles the observer - it surpasses his understanding.
To clarify, a supernatural event is not just one that baffles the observer - lots of natural stuff baffles observers all the time. Same with measurement - there's lots of stuff out there in the physical universe that we haven't measured and can't currently measure. Something supernatural would, presumably, violate the laws of nature or be completely beyond measurement because by definition it is beyond nature.
So here's the critical decision point: if we observe something that we can't explain, or can't measure, how do we know if it's something supernatural, or something natural that we just don't have enough information about yet?
I think this question is unanswerable, which is why I don't think we can ever conclude that something is supernatural. There is always a possibility it will turn out to be natural once we learn more about it - which has happened many, many times in the history of human discovery. Feel free to tell me if you think I've got it wrong.
Do you find that different to a force that indicates a presence, but cannot be currently measured - such as 'dark energy' as one example?
Dark energy is a proposed natural explanation for a phenomenon we've observed. The difference between that and a supernatural explanation is that dark energy can at least some day, once we get the proper technology, be tested and/or falsified. Supernatural explanations can't, they're unfalsifiable.
If there were no instruments to measure wind, magnetism, and other forces, these phenomenon would still exist, and their effects observed, even if not understood scientifically.
Correct. And we would be wrong to ascribe a supernatural explanation to them simply because we don't understand them. That would be an argument from ignorance.
Did you read the small excerpts I included in the post?
They have not - cannot - directly observe them. What we can observe, is affected by something - some unobserved force.
So, based on what appears to be a misunderstanding, I think I should ask the question again. Why do you accept these hypotheses?
Full disclosure, I have only done minimal research on this topic. So I really don't know that much. So when you ask, do I "accept these hypotheses" - I think they're plausible? They could very well be wrong. I don't know, because I don't have the physics knowledge to really understand the complexities of these ideas. I should do more reading on them, I just haven't.
So you are convinced of something that cannot be directly observed. You consider it to be real, because whatever it is... whatever is there... it has an effect on matter. So you believe. Agreed?
I believe there is something causing this phenomenon yes. And I'm highly confident that something is going to be a natural rather than a supernatural thing, because all the other verified causes of everything else we know of in the universe have been natural.
Do you require a measure of faith to believe that it is what others have proposed, or suggested, as an explanation for the phenomenon?
That depends on what you mean by faith. Confidence? Yes, I have confidence that physicists are the most capable people on the planet of accurately answering these questions. Belief in the absence of evidence? No.
Oh. I see. Can you elaborate please. It sounds interesting.
Let me think...let's take the Loch Ness monster. The idea that there's a plesiosaur hanging out in a loch in Scotland can be tested by - going and looking in Loch Ness, and say, seeing him and videoing him (not the crappy home videos of floating logs, I mean like Nat Geo quality video).
We can't do that with, say, I don't know, what's inside a black hole. I'm just spit balling here. I just mean that different hypotheses require different tests to verify them.
Now you will have to explain what you mean by empirically detect something, since you have said you believe, and are convince that something is true even though it cannot be directly observed.
Sorry, by directly observe I was thinking of actually seeing something with my own eyes. "Empirically detecting" would be like using instruments.
