Sep 22, 2020 · Dark matter is a mysterious non-luminous substance making up the vast majority of matter in the universe. Though experts have observed the gravitational effects of dark matter for decades ...
Dec 6, 2018 · Dark matter keeps galaxies and galaxy clusters from coming apart at the seams, which means dark matter experiences gravity the same way we do. Animation illustrating light from a cluster of galaxies being lensed by dark matter. In addition to holding things together, it distorts space like any other mass.
Mar 3, 2020 · Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb ...
Dark Energy and Dark Matter. All the atoms and light in the universe together make up less than five percent of the total contents of the cosmos. The rest is composed of dark matter and dark energy, which are invisible but dominate the structure and evolution of the universe. Dark matter makes up most of the mass of galaxies and galaxy clusters ...
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster. The galaxies in the Coma Cluster were moving too quickly for as much mass as there appeared to be, and dark matter was a potential explanation.
Jun 21, 2023 · Dark matter is an invisible type of matter that exerts gravitational effects on light and regular matter. Dark matter is a hypothesized form of matter that does not interact with light or other forms of electromagnetic radiation, but exerts gravitational effects on visible matter, light, and the structure of the universe. Scientists calculate ...
Sep 8, 2020 · What is dark matter? Dark matter is an unknown collection of particles that cosmologists believe contribute to the gravitational field of the Universe, and out-weigh normal matter by around five to one. The existence of dark matter has been suspected since the first half of the twentieth century. The first evidence comes in the 1930s when Swiss ...
