Structural Origin of a Universal Acceleration Scale in Causal Cosmology

Key Points

The aim is to establish a universal acceleration scale derived from causal cosmological principles.
Applied concepts of relativistic causality and dimensional consistency.
Examined the implications of the cosmological horizon on acceleration scale.
Demonstrated the emergence of an acceleration scale independent of other cosmological models.
Identified an acceleration scale of order a0∼cH0.
Showed that the scale is a structural consequence, not influenced by dynamics or modified gravity.
Established the acceleration scale as a constraint within cosmological theories.

Abstract

This work establishes the existence of a universal acceleration scale as a structural consequence of causal cosmology. Using only relativistic causality, dimensional consistency, and the presence of a cosmological horizon, we show that an acceleration scale of order a0∼cH0a₀ c H₀a0∼cH0 necessarily emerges, independent of galactic dynamics, phenomenological fitting, or modified gravity models. The result functions as a structural constraint rather than a dynamical explanation.
