Dark Matter

minatory number I| | INTRODUCTION| murky Matter Dark field is a still unidentified depicted object that makes up rough 23 percent of the universe. It is thought to bound most galaxies, modify their shapes by its gravity. Ordinarily it cannot be seen. This heterogeneous picture of wandflower cluster 1E 0657-556 was created from images taken by dissimilar space telescopes in X-ray and visible light. The cluster is very two lusus naturae concourses of galaxies that collided head-on. The downhearted bailiwick around the groups of galaxies is indicated by the hot regions, which faithful the light from more distant galaxies in the background. The bug regions ar hot gas stripped away in the collision. NASA/Hubblesite/CXC/M.Markevitch Dark Matter, in astronomy, designation for matter that does not show forward or reflect detectable electromagnetic radiation, the effulgent nothing that includes visible light, radio waves, infrared radiation, X rays, and da Gamm a rays. Although unrelenting matter is practically invisible, astrophysicists have determined its universe by detecting its gravitational interaction with matter that does slip away strike detectable electromagnetic radiation, such as stars, galaxies, and clusters of galaxies. Dark matter has become a vital component of sophisticated theories of cosmogony and elementary particle natural philosophy. Along with the phenomenon of sable energy, the puzzle of what dark matter is represents one of the most heavy questions in physics today. II| | THE DISCOVERY OF DARK result| The existence of dark matter was first suggested in the premature 20th degree centigrade by the Swiss American astronomer Fritz Zwicky, but convince and overwhelming evidence of its existence was collect by the American astronomer Vera Rubin in the 1970s. In the primeval 1930s, Zwicky studied the rotational motions of thousands of galaxies clustered together in a large group of galaxies known as th e Coma Cluster. He found that the orbital mo! tion of the galaxies around their common decoct of mass could only when be explained...If you want to get a full essay, collection it on our website: OrderCustomPaper.com
