The (electromagnetic radiation / gravity) of dark matter causes baryonic gas and dust to (clump together / break apart).

The gravity of dark matter causes baryonic gas and dust to clump together.

The gravity of dark matter causes baryonic gas and dust to clump together. Dark matter does not interact directly with electromagnetic radiation, as it does not emit, absorb, or reflect light. However, its gravitational influence on baryonic matter leads to the formation of structures such as galaxies, galaxy clusters, and larger cosmic structures.

The gravity of dark matter causes baryonic gas and dust to clump together.

To understand why, let's break down the question. Dark matter is a type of matter that does not emit, absorb, or reflect light, making it difficult to detect. However, scientists believe that dark matter makes up a significant portion of the total matter in the universe.

Dark matter interacts primarily through gravity, which means it can influence the motion of other matter, such as baryonic gas and dust. Baryonic matter is the ordinary matter that we can see, including protons, neutrons, and electrons.

When dark matter is present, its gravitational pull attracts surrounding baryonic matter. This attraction causes regions of higher density in the baryonic gas and dust, leading them to clump together.

As these clumps grow larger, their gravitational pull becomes stronger, attracting more gas and dust. Over time, this process can form structures such as galaxies, galaxy clusters, and even larger cosmic structures.

So, to summarize, the gravity of dark matter causes baryonic gas and dust to clump together, leading to the formation of various cosmic structures in the universe.
