According to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), dark matter is by far the most plentiful material in the universe.
The presence of dark matter causes baryonic gas and dust to | (a) clump together and form galaxies | (b) become invisible | (c) evaporate | (d) explode
To select the correct answer, we need to understand the question and the options provided.
The question is asking about the effect of dark matter on baryonic gas and dust. Dark matter is a hypothetical form of matter that is thought to make up a significant portion of the total mass in the universe, but it does not interact with light or other electromagnetic radiation. Baryonic matter, on the other hand, is the type of matter that we are more familiar with, such as protons, neutrons, and electrons.
Now, let's take a look at the options provided:
a) "reflection of dark matter causes baryonic gas and dust to evaporate"
b) "influence of dark matter causes baryonic gas and dust to form galaxies"
c) "presence of dark matter causes baryonic gas and dust to collapse into stars"
d) "pressure from dark matter causes baryonic gas and dust to disperse"
To determine the correct answer, we need to consider the known interactions of dark matter with baryonic matter. Since dark matter does not interact with electromagnetic radiation, it does not directly cause baryonic gas and dust to evaporate, form galaxies, or disperse due to pressure. Additionally, while dark matter does have a gravitational effect, it does not cause baryonic gas and dust to collapse directly into stars.
Therefore, the correct answer would be option b) "influence of dark matter causes baryonic gas and dust to form galaxies." Dark matter's gravitational influence is thought to drive the formation and growth of structures in the universe, including the formation of galaxies and galaxy clusters, by attracting and influencing the behavior of baryonic matter.
