# Close Binary Galaxies: Application to Source of Energy and Expansion in Universe

## TL;DR

This paper explores the evolution and energy transformation in binary galaxy systems by applying nuclear fusion concepts to galactic dynamics, revealing how symmetric binaries form and release energy during symmetrization.

## Contribution

It introduces a novel application of nuclear physics ideas to galactic systems, analyzing the formation and energy processes of binary galaxies.

## Key findings

- Stable symmetric binary galaxies can form under certain conditions.
- Symmetrization converts gravitational energy into internal energy, releasing large amounts of energy.
- The process influences galaxy evolution and energy distribution.

## Abstract

Applying the microscopic nuclear physics ideas for fusion reactions to macroscopic galactic systems, we study the evolution of the compact binary galaxy in mass asymmetry (transfer) coordinate. The conditions for the formation of stable symmetric binary galaxy are analyzed. The role of symmetrization of asymmetric binary galaxy in the transformation of gravitational energy into internal energy of galaxies accompanied by the release of a large amount of energy during the symmetrization process is revealed.
