The forgotten cause is to be found in the various sources of energy producing movement, in experimental settings in which, especially, the contamination with radon is not checked. Other sources of movement as well interact with the experiments - sometimes the experimenters’ imprecise behaviour leads to the result. The issue of the “Vacuum catastrophe” is hence solved. http://pubs.sciepub.com/ijp/7/3/5/ijp-7-3-5.pdf Bose-Einstein condensates helium superfluidity Casimir effect vacuum energy vacuum catastrophe
