[28] [29] Rubin's results were confirmed over subsequent decades, [1] and became the first persuasive results supporting the theory of dark matter, initially proposed by Fritz Zwicky in the 1930s. [1] [12] [30] This data was confirmed by radio astronomers, the discovery of the cosmic microwave background, and images of gravitational lensing.
In astronomy, dark matter is a hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
Sandra M. Faber (1944–) discovered the Great Attractor, a supercluster-scale gravitational anomaly; co-inventor of the theory of cold dark matter Hume A. Feldman (1953–) studies cosmological perturbations and the statistical and dynamical properties of the large scale structure of the universe
Researchers propose that dark matter particles could interact with Earth's ionosphere. This theory may lead to the first observable signs of dark matter.
The universe's contents include ordinary matter - stars, planets, gas, dust and all the familiar stuff on Earth, including people and popcorn - as well as dark matter, which is invisible material ...
The density of dark matter in an expanding universe decreases more quickly than dark energy, and eventually the dark energy dominates. Specifically, when the volume of the universe doubles, the density of dark matter is halved, but the density of dark energy is nearly unchanged (it is exactly constant in the case of a cosmological constant).
The cosmological constant was originally introduced in Einstein's 1917 paper entitled “The cosmological considerations in the General Theory of Reality”. [2] Einstein included the cosmological constant as a term in his field equations for general relativity because he was dissatisfied that otherwise his equations did not allow for a static universe: gravity would cause a universe that was ...
Look no further than the missions racing to unlock dark matter and the mysterious force known as dark energy, both so named precisely because science has yet to explain these phenomena.
