I have had an idea regarding an experiment similar to that of the "Double Slit" experiment that most of you will be familiar with
For those that aren't familiar watch the video below.
My idea stems from this, but expanded upon only slightly.
What if the observation method was done from another room. Astral projecting. Would be interesting to see what results this yields. I understand it's not something I can practically ask any of you to do, I don't know many people with Particle Accelerators in their front rooms... Nor do I know any Astral travelers that can pick up on the energy of a single particle (Though I have heard rumours/stories of such possibilities)
For now this shall remain a theretical debate,
