I think I need to rephrase the question. I'll post again in a few days.
The replies so far have generally been very polite, given the subject. I was nervous about that. Thanks everyone!
... Hear me out, okay?
Back in 2000 I took my first solo, out of state trip, to meet an online friend. When I got off the bus, she greeted me, and let me know that we had to go stop by her friends house on the way back.
She was Wiccan and needed some Spiritual guidance because the night before she saw a black portal open up in the corner of her room that was giving her really bad vibes.
It wasn't my thing, but I never discounted it. Maybe it was real, and if nothing else it's just how her mind is rationalizing things.
But I guess my question is: Does the Scientific Method rule out the possibility that a "real" portal appeared in her room?
Taking wave function probability into account and the absense of data from the room, is it fair to say that the scientific method doesn't rule out the black portal being real?
Looking for black and white answers if possible, but I'd also love to hear your reasoning~
Given there available evidence, the theory that your friend was hallucinating or just lying is far more plausible and therefore preferable. However, it's fundamentally impossible to prove the non-existence of anything. The scientific method can only positively prove that something exists, not prove that something doesn't exist.
I'm gonna rephrase the question and post it again in a few days. I don't think I was able to convey the question properly.
