A Modified Mass Concept could explain both the Dark Matter and the Dark Energy Phenomenon

TL;DR

A Modified Mass Concept proposes a scalar field-based approach that explains galactic rotation, universe inflation, and accelerated expansion without dark matter or dark energy, unifying these phenomena through inertia modification.

Contribution

It introduces a scalar field-dependent mass model that accounts for cosmic phenomena typically attributed to dark matter and dark energy, offering an alternative to standard cosmological models.

Findings

Explains galactic rotation curves without dark matter

Describes universe inflation and acceleration without dark energy

Predicts a constant energy density in the late universe

Abstract

Some consequences of a Modified Mass Concept (MMC) are discussed. According to MMC the inertial mass is not only determined by its energy, but also by a scalar field f depending on other masses. The concept consistently describes the galactic rotation curves, the inflation of the universe and its accelerated expansion, all without the necessity of Dark Matter (DM) and Dark Energy (DE). Instead, the effects attributed to DM are caused by a reduction of inertia acting as an enhancement of gravity. These results of MMC are similar to that of MOND. The effects usually attributed to DE in MMC stem from a new equation of state for baryonic matter, which always causes a negative pressure. In this respect the results are similar to those of the two component LCDM. In particular, according to MMC the late universe will pass into a state of constant energy density. Furthermore, the MMC can provide an explanation of the very high peculiar velocities found at large scales.
