Is dark matter dark because we hav never measured it directly on Earth with the atom?

Mordred said:The term dark merely infers that little is known about the two.
Dark matter is called "dark" because it does not interact with light or other forms of electromagnetic radiation. This means that it cannot be detected by telescopes or other instruments that rely on light to observe objects in space.
Dark matter is different from regular matter because it does not emit or absorb light, and it does not interact with other forms of electromagnetic radiation. This means that it does not reflect, absorb, or emit any type of electromagnetic radiation, which makes it invisible to traditional forms of observation.
Atoms are visible because they interact with light and other forms of electromagnetic radiation. When light hits an atom, it causes the electrons in the atom to move, which results in the emission of light. Dark matter, on the other hand, does not interact with light, which makes it invisible to traditional forms of observation.
No, dark matter is made of different particles than regular matter. Regular matter is made of atoms, which are composed of protons, neutrons, and electrons. Dark matter is thought to be made of particles that do not interact with light, such as weakly interacting massive particles (WIMPs) or axions.
Dark matter is important to the study of the universe because it makes up about 85% of the total mass in the universe. It also plays a crucial role in the formation and evolution of galaxies, as it provides the gravitational force needed to hold galaxies together. Understanding dark matter is essential to understanding the structure and evolution of the universe.
