Then you are attempting the wrong way.<quoted text>
And this is in spite of many, many attempts to find a way to measure it. At what point do we simply admit it doesn't exist?
All forces occupy space. Space is part of the circuitry of the universe. If you are just measuring the energetic paths, what we call matter, with matter, then you will miss a lot. Those forces transverse space. Space is a carrier.
Space is essentially the ground plane. You have to develop a method to read changes in it. Believe or not, you do that with material observation. You are inserting a resistance or displacement, and thus a polarity.
