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 & smooth manner. We summarize our results by definitions, propositions & theorems. We are classes from grade 10 or higher, courses, research clubs, enthusiasts, observers, experimentalists, mathematicians, scientists, researchers …
