Dark matter and dark energy make up the majority of the massenergy content of the universe from "summary" of The World of Physics 2nd Edition by John Avison
Dark matter and dark energy are two mysterious components of the universe that play a crucial role in shaping its structure and behavior. Despite their invisible nature, they are believed to make up the majority of the mass-energy content of the universe. Dark matter, which does not interact with light or other forms of electromagnetic radiation, exerts gravitational forces that hold galaxies together and affect the motion of stars within them. Scientists have long been puzzled by the elusive nature of dark matter, as it cannot be directly observed or detected using traditional astronomical methods. On the other hand, dark energy is thought to be responsible for the accelerated expan...
