Dark matter
Dark matter is a universe component whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter is a mysterious substance thought to compose perhaps about 27% of the universe’s makeup.
It is called “dark” because it does not appear to interact with the electromagnetic field. This means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, hard to spot.
