Notes on Physics

Wrong statements

GR is based on Einstein field equations, which determine the geometry of space-time as a consequence of the energy and matter that is in the space-time.

Error: energy and matter isn't in space-time. all the three (or better, four) cited physical entities are phenomena, manifestations produced by the dynamics of the same Elementary Field, under the incessant pressure of the Fundamental Force, the two aspects of the Primary Source of Reality.

Hypotheses

Matter with "negative energy density" --> ? --> Hp... Dark Energy or Dark Matter? Conventional: positive density --> DM and OM, negative density --> DE ???

What does the work to sustain the inertia, the ability of em radiation and matter to continue to move at the same speed if no force acts on it (including curvature of st)? It is the Source creative expression, produced by the inner interaction between its active and passive aspects, the FF and the EF. This fundamental interaction produces the EE, whose inhomogeneity represent the Elementary Action, the only "substance" that forms the Reality and the Universe in evolution. Sounds magic? Please, think about it without prejudice.

Space-time, as manifestation of the dynamics of EF, is a field of velocity, exactly like the gravitational field, the curvature of st and gravity are the same, as acceleration. Absolute flat st = full inertia, no acceleration.

No acceleration = inertia
