About this document
Dark Matter and Energy Overview by Jatoi Akhtar is a document available to read on EtoBox.
Dark matter makes up about 21% of the total mass-energy of the universe but does not interact with electromagnetic radiation and can only be detected through its gravitational effects. Dark matter played a role in the early formation of galaxies and holds galaxies together through halos of dark matter. Dark energy is thought to be responsible for the accelerating expansion of the universe and makes up about 75% of the mass-energy but its true nature remains a mystery.
