Articles on the Casimir effect do not mention any relationship between gravity and the Casimir effect although an article on (http://physicsweb.org/articles/world/15/9/6) does mention ongoing experiments using different materials to neutralize the local gravity. I have come across a gravity/Casimir effect relationship that might be just a mathematical coincidence or it might be applicable to current studies; it implies that the force of the Casimir effect should vary with changes in the Earth’s gravitational force affecting the experiment. I should like to know if this is a known or predictable effect, or if it has already been proven to be incorrect. Have separate experiments (preferably using the same equipment), been conducted on the Earth's surface and repeated in deep mines or space? Please keep in mind that I have no professional training and do my work using linear (not quantum) physics, so replies need to be simple.
