Contrary to popular belief, the uncertainty principle has another meaning, which is explained by the wave function and may be even more important when combined with Einstein's teachings, apart from the fact that the measurements must include "a certain uncertainty": according to this, the narrower the domain of a particle and the shorter the range, the energy of that particle. hence its mass must increase by that much; narrowing the position causes the wave function to fluctuate, increasing the fluctuation increases the speed, speed increases the kinetic energy, and energy increases the mass. (see: wave function) (see: emc2) The result of all this is that space-time has lost its continuity and that space and time have quanta.
