Answer : Dark Matter.

Explanation :

The primary type of matter influencing the gravitational interaction leading to Milkomeda's formation is dark matter. Milkomeda refers to the future merger of the Milky Way and Andromeda galaxies, driven by their mutual gravitational attraction. Dark matter, which outweighs visible matter in both galaxies, dominates their mass and gravitational pull, significantly shaping the dynamics of their approach and eventual collision over billions of years.

Normal (baryonic) matter
Many people choose this because stars, gas, and dust are what we actually see, and they assume the visible parts of the galaxies are what pull each other together. In reality, normal matter makes up only ~15–17% of the total mass of each galaxy; dark matter dominates the gravitational interaction on these large scales.
