Sorry, I was merely replying to your comment.

Taking gravity as an example (simpler than magnetism, no cross-products, Curie points etc..), the PE lost by the falling weight is exactly equal, _by definition_, to the work that must be done to lift it back up. If PE wasn't real there would be no real counterpart to the real work done when lifting the weight, as there would be no counterpart to the kinetic energy of the weight when it falls. > Besides you can't replace PE by a _quantifiable_ energy as you suggest (annihilated or weakened electrons), because PE has an arbitrary zero. We can't tell how much intrinsic PE there is in the weight because we don't know on which planet we are going to let it fall, agreed? --- No offense intended, but it seems you are not grasping the depth of my theory, as what you say adds even more credence to my theory, which dismisses the idea of PE; i.e., you don't know how much PE you'll ever need. If you carefully read this entire reply I believe you could only agree with my theory in all honesty. Two iron atoms could have been created 1 micron apart, which would constitute a certain amount of PE. The iron atoms could have been created in different solar systems, which would constitute a certain amount of PE. The iron atoms could have been created in different galaxies, which would constitute a certain amount of PE. The iron atoms could have been created in different universes/big-bang (see M-theory on beyond our big bang), which would constitute a certain amount of PE. You are asking way too much from nature. I've written far too many simulation programs to know such an idea as PE is a nightmare for the simple reason that you can ***add*** energy to the system from nowhere. This is very clear and simple in a simulation program. If you want to add more energy to the system you simply create two iron atoms that are even farther apart and then allow them to accelerate toward each other. :-( My theory simply states energy is simply moved from one location to another. When the two magnets accelerate toward each other it consumes energy. And guess what, my theory is already confirmed as much as we know two air core electro-magnets do indeed consume energy as they accelerate toward each other. Ah, and here's another surprising confirmation. :-) We now have technology to create electric fields on demand, which is in complete agreement with my theory. Consider two separated objects. One is negatively charged and the other is positively charged. When separated there exists an appreciably charged space, which constitutes energy. We know that it requires energy to charge space-- capacitors. As the two objects accelerate toward each other the net electric fields decrease, as the negative & positive fields cancel. :-) In a nutshell, we started with energy that constitutes charged space, and we ended up with "energy," the moving object. Lets see if the theory holds up to the opposite situation-- two objects charged with the same polarity. Again we initially have charged space. It requires energy to force the two objects closer together. This consumed energy goes in the way of charged space, as the two fields overlap. To top it all off, my theory is far simpler. In physics we strive to find the most fundamental theory. Your theory requires KE and PE. My theory requires one, plain old "energy." :-) I am sorry, but IMHO the evidence is overwhelming that my theory is correct-- knock on wood, lol. Think about it for a while.
