I see this a strength, not a weakness. Note that if black holes increase density, then you *need* a decrease in density....which leads to another thought. If a magnetic field is caused by "pile up" of aether in front of a moving charged body, then there should be a decrease in density behind it. :) >While my relativistic theory doesn't exactly match either concept the "up >shifted" concept Thomas Prevenslik first introduced me to comes from a thermal >dynamic perspective of Casimir effect - I used to consider this the "other" >camp for Casimir theory vs. the "displacement" camp that I was more >comfortable with - Thomas comes at this from a perspective of thermal >dynamics and will argue the plates are not "pushed" together and that ether >doesn't need to exist to explain the effect, he explains the effect as an >imbalance created by "up shifting" causing the plates to self attract. Milonni wrote a paper that was based on attraction. I think this is in Phys. Rev. A, #25 page 1315 (1982).
