gravity
To determine the correct answer, let's first understand the concepts involved.
Dark matter is a hypothetical form of matter that is not directly detectable through electromagnetic radiation. It does not interact with light or other forms of electromagnetic radiation, hence the term "dark."
Gravity is the force of attraction between objects with mass. It is responsible for the clumping of matter at various scales, such as forming galaxies and galaxy clusters.
Baryonic gas and dust refer to ordinary matter composed of protons, neutrons, and electrons. These are the building blocks of atoms and are the only form of matter that interacts through electromagnetic radiation.
Now, considering this information, we can answer the question.
The correct answer is:
The gravity of dark matter causes baryonic gas and dust to clump together.
Dark matter, despite being invisible, has gravitational effects on visible matter. It exerts a gravitational force on baryonic gas and dust, causing them to gather in denser regions over time. This gravitational clumping is one of the observed effects of the presence of dark matter in the universe.
