I would like to say that many of the things discarded over the centuries have been in the area of what used to be woo. Science has actually come up with inventions, devices, and all manner of delicately precise instrumentation to detect/discover woo. And positive physical detection (of something, anything, that contains energy) is what science is all about. Ghosts, if one believes in them, are energy at some level, so is psychic energy. Everything that is generally in the area some woo emits energy. A portal open or closing is an energy disruption in the fabric of both electromagnetic energy, including the visual spectrum, as well as the molecular arrangement in any given field or medium.
And science is there, and apparently the woo isn't. I don't know everything, so maybe science will end up with some kind of new valid method of testing for such things. The point is science in the end should be able to see woo on their instruments. And if science can pick up the physical reaction of a plant when the person walked into a room and hacked off it neighbor growing in the pot next door? Then maybe only greater precision instruments are what is needed. And I almost hate to say it but if science can't seem to detect woo, it hasn't been for lack of trying. Now. Our lovable Sasquatch on the other hand has all of the physicality necessary for scientific detection. Psychic, portal jumping, telepathy and whatever else notwithstanding.
