Is the spherical shock front the only excitation that pumps volume into its carrier field, such that it locally deforms and globally expands?

A spherical shock front is a solution of a second order partial differential equation, such as the well known wave equation. The shock front is not a wave and it is not a wave package. During...

The Hilbert Book Model introduces ultra-high frequency waves that cannot be observed but that configure potentials. Sensible model?

At every progression step elementary particles emit wave fronts. These wave fronts combine into ultra-high frequency waves. On their turn these waves constitute the potentials of the particle. The...
