According to measurements made by the Wilkerson Microwave Anisotropy Probe (WMAP) , which material is by far the most plentiful in the universe?
According to measurements made by the WMAP, dark matter is by far the most plentiful substance in the universe. Dark matter is a form of matter that does not emit, absorb, or reflect electromagnetic radiation, making it invisible to telescopes. It is estimated to make up about 27% of the universe's total mass-energy.
According to measurements made by the Wilkerson Microwave Anisotropy Probe (WMAP), the most plentiful material in the universe is hydrogen.
To determine the most plentiful material in the universe according to measurements made by the WMAP, we need to consider the composition of the universe and the observations made by the probe. The WMAP is a satellite designed to capture data on the cosmic microwave background radiation, which provides valuable insights into the early universe and its composition.
The WMAP measurements have revealed that the universe is composed mainly of dark matter, dark energy, and normal matter. However, it is important to note that dark matter and dark energy are not directly detectable, which leaves us with normal matter to consider.
Normal matter, also known as baryonic matter, consists of protons, neutrons, and electrons—the building blocks of atoms. This includes the familiar elements found on Earth and throughout the universe.
Based on the measurements made by the WMAP, it is estimated that hydrogen is by far the most plentiful material in the universe. Hydrogen is the lightest and simplest atom, comprising one proton and one electron. It is a fundamental building block for all other elements and is found abundantly in stars, interstellar gas, and other cosmic structures.
Therefore, according to the observations made by the WMAP satellite, hydrogen is the most plentiful material in the universe.
