On the origin of the rhythmic Sun's radius variation

TL;DR

This paper reports a novel observation that the Sun's radius variation correlates with planetary positions, suggesting an unknown external influence possibly from dark matter streams affecting solar dynamics over months to years.

Contribution

It proposes a new planetary relationship with solar radius changes and hypothesizes an influence from dark Universe matter, a concept not previously considered in solar physics.

Findings

Solar radius varies with planetary cycles.

Correlation suggests influence from external unseen matter.

Impact from dark sector may affect solar behavior over months to years.

Abstract

The Sun shrinks during solar maximum and regrows during solar minimum by a few kilometers. Here, we observe, for the first time, that the solar radius variation shows planetary relationship. This suggests that some remote planetary links must exist, even though this is unexpected within known physics. Therefore, we speculate about its cause, which is the driving idea behind this investigation. Namely, it must be some generic as yet invisible streaming matter from the dark Universe. The associated energy change is massive although it extends from months to several years. The impact by the tentative invisible massive matter accumulates with time, triggering slowly the underlying processes. This study shows that the sun size response is as short as a few months. Then, the solar system is the target and the antenna of still unidentified external impact, assuming to be from the dark sector.
