Matter density in space
Web13 dec. 2024 · Density is a measure of how much matter (mass) there is in a given amount of space (volume). The lower the density, the more spaced out the particles are. The … WebDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect. Various astrophysical …
