How Volume Portions Form and Found Light, Gravity and Quanta

Volume in nature is a foundation of present-day physics.
The volume dynamics, VD, is implied by evident properties:
invariance of the speed of light and zero rest mass of volume

The VD includes:
– the existence and reality of volume portions, VPs
– change tensors of VPs, including electromagnetic waves
– the differential equation describing change tensors, form of wave packets, formation and propagation of VPs
– real quantities are identified via the Hacking criterion

The VD implies and explains present-day physics, e. g.
– gravity and transmission of gravitational interaction
– curvature of spacetime
– general relativity as a semiclassical and averaging approximation
– universal formation of quanta, a generalized Schrödinger equation, the postulates of quantum physics
– the Schrödinger equation as a nonrelativistic approximation
– an improved and generalized version of quantum field theory, including nonlocality & causality, without infinity – as expected, as real volume inside the light horizon cannot cause a real infinity

The VD implies, explains and clarifies properties of space, e. g.
– VD implies density of volume in our heterogeneous universe
– VD provides the time evolution of the Hubble constant (front cover), this solves the Hubble tension
– real VPs represent the wave function and its generalization
– VD clarifies real zero-point-oscillations, real Casimir force and real VPs and solves the cosmological constant problem
– causality with nonlocality is clarified
– formation of matter has been derived
– the era of cosmic ‘inflation’ has been derived and clarified
– the elementary charge, the electroweak couplings and many elementary particles have been derived and explained
– the cosmological parameters have been derived fundamentally

Thus, the VD clarifies, generalizes and unifies present-day physics. All results are in precise accordance with observation. Thereby, no fit has been executed, and no hypothesis has been introduced.

We derive all findings in a systematic, clear and smooth manner. We summarize our results by definitions, propositions and theorems. We are classes from grade 10 or higher, courses, research clubs, enthusiasts, observers, experimentalists, mathematicians, scientists, researchers...
