Researchers at the University of Lisbon in Portugal have proposed an explanation for EmDrive, which has yet to be explained in terms of conservation laws. In their opinion, the engine does not violate the known physical principles if its operation is considered in the framework of the pilot wave theory. The article by scientists was published in The Journal of Applied Physical Science International, according to Science Alert.
Pilot wave theory explains concepts such as wave function collapse and Schrödinger's cat paradox from the point of view of classical physics. According to this concept, all the uncertainty arises from the fact that the particles have a certain position and momentum, but these parameters are unknown to the observer. However, the currently accepted Copenhagen interpretation of quantum mechanics asserts that uncertainty is inherent in the particles themselves.
According to scientists, the pilot wave theory states that an object generates a field, and then is attracted to certain areas of that field, where the energy density is highest. Simulation results showed that a sufficiently strong and asymmetric electromagnetic field produced by the cone-shaped EmDrive can act as a pilot wave. This is what creates cravings.
