real quasi-particles

[AntonioLao]

In an effort to make sense why the true vacuum must exist is tantamount to questioning the reality of quasi-particles.

As pointed out in the 3rd paragraph of page 1, Volume 9, Statistical Physics, part 2: Course of Theoretical Physics, a successful physical theory must ultimately consider the important of the following fundamental point of view: any weak excitation of a macroscopic body must be quantum mechanically considered as separated elementary excitations. These form a dynamic system of quasi-particles in a volume exclusively defined for the macroscopic body in question. Within the confine of this volume, the distribution of these quasi-particles defines a unique energy spectrum. Outside this volume and collectively of all macroscopic bodies (e.g. atoms), the energy spectrum of quasi-particles and that of the individual atoms and molecules cannot be distinctively identified.

For each level of existence (LOE), different manifestations of quasi-particles can be described meaningfully. For the entire universe, its quasi-particles are galaxies. For a galaxy, its quasi-particles are stars. For a star, its quasi-particles are the chemically ionized elements. For each chemical element, its quasi-particles are the electron and nuclei of proton and neutron. For each baryon and meson, its quasi-particles are the quark constituents.

Traversing these different LOEs, transporting energy or mass or both depending upon the collision cross section, are the various types of bosons: photons, gravitons, gluons, and other integer spins particles called W± and Zº.

The true vacuum supports the universe. Without it the universe will collapse back into a singularity or a black hole.

We all need support,or we will all collapse!
