I place no faith in the einsteinian stuff - seeing it as bunk sold to Us because it does not predict the energy in the aether. With ad hoc "dark matter," "dark energy," and "bending of spacetime" to make it all work. Not to mention "renormalization..."
Far better was the late Dr. Paul A. LaViolette's SQK (subquantum kinetics) where He used the "as above, so below" principle, taking chemical kinatics and applying them to the subatomic realm.
SQK predicts all the "mysteries" of the einsteinian bunk, including the Biefeld-Brown effect, needs no as hoc matter, energy, renormanization, and is euclidean.
