Phonons, stable solutions i momentum space of Field theory, at zero temperatures and superfluid conditions have been proved to be part of acoustiv waves that transfer mass due to gravitationally inflicted pressure differences in superfluid that makes the trajectory of wave non straight line.
If one extends this to vacuum phenomena with hypothesized superfluid conditions and photin excitations in the other parts of the standard momentum space curve, is it possible to discilover alternative explanation to gravitational lensing, explained by Einstein's General Relativity?
