Intersting comments and observations Chumbly, thanks for sharing that. I agree with Nakis good post.
Oh but to have the crystal ball of truth and knowledge for the realms of the paranormal, we could remove the bubble that envelops those minds demanding proof to dispell logic. I like most everyone needs proof from time to time and certainly look for the logical or plausible explanation first. However I also know there is much yet to be discovered and explored and that which may never be explained to close my mind for but one explanation. You have given some food for thought here.
I imagine when it comes to orbs there is not just one explanation to them but several that may lend credence to both scientific and paranormal thinking. We just now need to determine which of those an orb is when it is captured on film or seen by the naked eye.
Having witnessed one first hand with my naked eye in a dimly lit room that no light reflection or camera flash could have caused, which occured directly after seeing an apparition, I know for certain in my own mind that spirit/ghost orbs do exist. Having witnessed the wonders of mother nature and her electrical energy I believe that some of those balls or flints of light we see or capture on film may simply be just that. I can't explain how the latter comes to be as I do not have the scientific mind and knowledge nor can I explain how a spirit/ghost manifests into an orb for I am still of body, but it's a pretty cool talent.
What a boring world this would be if we had only one explanation for everything we see, touch, smell, taste, hear and acquire knowledge of. =)
