According to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), which material is by far the most plentiful in the universe?(1 point)
dark matter
dark matter
dark energy
dark energy
neutrinos
neutrinos
baryonic matter
The correct answer is "dark matter."
According to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), the most plentiful material in the universe is dark matter, not dark energy, neutrinos, or baryonic matter.
To find the answer to this question, we can refer to the measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP). The WMAP is a space probe that was launched by NASA in 2001 to measure the properties of the cosmic microwave background radiation. The cosmic microwave background radiation is the residual heat left over from the Big Bang and is an important source of information about the composition and evolution of the universe.
According to measurements made by the WMAP, the most plentiful material in the universe is baryonic matter. Baryonic matter refers to ordinary matter made up of protons, neutrons, and electrons, which form atoms and molecules. This includes all the familiar elements that we encounter in everyday life, such as stars, planets, and living organisms.
While dark matter and dark energy are also important components of the universe, they are not as plentiful as baryonic matter. Dark matter is a hypothetical type of matter that does not interact with light or other forms of electromagnetic radiation, making it invisible. Dark energy, on the other hand, is a mysterious form of energy that is believed to be causing the expansion of the universe to accelerate.
Neutrinos are subatomic particles that have very little mass and interact weakly with other matter. While they are abundant in the universe, they are not as plentiful as baryonic matter.
Therefore, the most plentiful material in the universe, according to measurements made by the WMAP, is baryonic matter.
