Contribution

It provides a qualitative overview of the problem, critiques existing theories, and suggests observable phenomena that could confirm local Hubble expansion.

Findings

Identifies key drawbacks in current theoretical models.

Proposes observable phenomena as potential evidence.

Highlights the importance of small-scale Hubble expansion studies.

Abstract

We present a brief qualitative overview of the current state of the problem of Hubble expansion at the sufficiently small scales (e.g., in planetary systems or local intergalactic volume). The crucial drawbacks of the available theoretical treatments are emphasized, and the possible ways to avoid them are outlined. Attention is drawn to a number of observable astronomical phenomena that could be naturally explained by the local Hubble expansion.
