>>14197506Casimir forces are basically the absence of most quantum wavelength from an engineered space, it's like the universal equivalent of atmospheric pressure is the easiest way to explain
>>14197719They were investigating the emdrive, and when that went to shit they continued to investigate engineered spacetime warping. The casimir force could be considered negative energy density because of how it works, so it might be able to stand in for the required exotic matter in the original solution
