The two types of baryonic matter that are most abundant in the universe are hydrogen and helium.
To determine the most abundant types of matter in the universe, scientists study the composition of celestial objects and analyze the light they emit. This can be done using telescopes and spectroscopy.
In the case of the universe, hydrogen is the most abundant element, making up about 75% of its baryonic matter. Helium is the second most abundant element, comprising about 24% of the universe's baryonic matter.
Therefore, the correct answers are:
- hydrogen
- helium
