An Analysis about the Origin and Essence of Mass Based on Particle-Propagating Model and Wave Equations of Scalar Waves

If the singularity of the cosmic Big Bang is taken as the origin of the reference coordinate system, the surrounding vacuum in the initial moments of it would exhibit radially-outward right-handed spiral motion at light speed.Based on this spatial motion hypothesis, we derive a unified field equation and a set of Maxwell's equations for vacuum SWs (Scalar Waves) generating a huge spiral force field that drives the energy to spiral inwardly and distort, leading to the formation of mass.Furthermore, they also uncover that mass is fundamentally an ultimate expression of energy, manifesting as the result of spiral motion of space at light speed.And then, we indirectly validate the theory that coherent light waves' collision generate SWs and subsequently mass through the experiment verifying the Breit-Wheeler process.The establishment of our theory offers a new analytical tool for the exploration of mass origin, the cosmic Big Bang, unified field theories.
