Abstract: 

This study explores the interplay between dark matter and negative gravitating mass, investigating their combined influence on the accelerated expansion of the universe. Our analysis reveals that when the effective mass, including dark matter contributions, exceeds matter mass, negative gravitating mass becomes dominant, leading to repulsive gravitational effects.

Key Findings:

Negative Gravitating Mass: The dominance of negative effective mass over matter mass results in negative gravitating mass (Mɢ < 0).

Repulsive Gravity: Negative gravitating mass generates repulsive gravitational effects, contributing to the accelerated expansion of the universe.

Dark Matter's Role: While the nature of dark matter remains uncertain, its gravitational influence contributes to the overall effective mass, impacting the dominance of negative gravitating mass.

Limitations of General Relativity: The observed accelerated expansion challenges the predictions of general relativity, necessitating the introduction of concepts like dark energy and negative effective mass.

Conclusion: 

Our research demonstrates that dark matter plays a pivotal role in shaping the gravitational dynamics of the universe. By incorporating dark matter into the total matter mass (Mᴍ), and considering the influence of negative effective mass (Mᵉᶠᶠ), we observe that the negative gravitating mass Mɢ becomes dominant. This dominance leads to repulsive gravitational effects, significantly contributing to the accelerated expansion of the universe.
