This seems to imply that for a particle that is absolutely at rest, its phase velocity is infinity. So, if the universe has zero linear momentum it's at rest for all practical purposes and hence its phase velocity is infinity but its wave function is also zero. |
Just suppose for a moment.that a particle was
in between attractions,and at temporary rest,would that be possible,and further is there not room in the theory for a momentary pause!
kind regards michael.
