About this document

Dark Matter and Dark Energy Explained by Camelia Canaman is a document available to read on EtoBox.

Dark matter is a mysterious substance that has mass but does not interact with light, making it invisible. It exerts gravitational pull and helps hold galaxies together. Dark energy is a form of energy that permeates space and causes the universe to expand at an accelerating rate, unlike gravity which causes things to come together. These two phenomena represent major unknowns in modern astrophysics.
