The theory behind Chernobrov and Frolov involves the aether, which in itself needs more evidence. Imagine every magnetic dipole, like one emerging from an electromagnetic solenoid or a bar magnet, being a “check valve” for the aetheric flow. One is outflow, the other is inflow. Now imagine creating a magnetic monopole. This is artificial, as to the extent of my knowledge, no natural magnetic monopole exists. The monopole is a unidirectional flow of the aether, and this time dilation. Their setup allegedly create such and altered the rate time flows
