Sometimes to understand things I need to come up with ideas and have them shot down. This is what I am doing here. I have been informed that the Cashmeir effect may not be due to negative energy so I have an idea for an additional experiment. Suppose we were to make a "box" with little "Pockets" and these "pockets" simulate the cashmeir effect by having the walls of the pockets be a very small distence from each other. If the cashmeir effect is indeed due to negative energy we would expect the box to weigh less than the materials that make it up, because the negative energy in the pockets would have negative mass. On the other hand I would assume this apparent decrease in mass would be very small, on par with weighing a photon. Futhermore gravity would most likely pull on the negative energy like it does postive energy so weighing the box would not be a simple matter of just putting it on a super acurate scale. I would love to hear all kinds of comments on this possible experiment.
