No one has ever found a single particle of dark matter. One underlying issue may be that materialist thinkers must see information as material, whether that approach fits information or not. Nonetheless, there have been some scattered successes for alternative hypotheses, such as a 2016 test of gravitational lensing in entropic gravity.The prevailing opinion among most astrophysicists is while modifications to general relativity can conceivably explain part of the observational evidence, there is probably enough data to conclude there must be some form of dark matter.Mention of dark matter is made in works of fiction. It can make things happen but not in quite the way a key fits a lock. It is a regular payload. In 1961, he predicted that erasing even one bit of information would release a tiny amount of heat, a figure which he calculated.
Categories Possibilities range from large objects like MACHOs (such as black holesNo known particles can be categorized as warm dark matter. Dark matter does not "weigh" anything.
I have had my Dark Matter for a little over a year now.
Dark matter is invisible, and scientists have long tried in vain to directly detect the mysterious particles. Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. The Bullet Cluster, the result of a recent collision of two galaxy clusters, provides a challenge for modified gravity theories because its apparent center of mass is far displaced from the baryonic center of mass.Baryon acoustic oscillations (BAO) are fluctuations in the density of the visible Dark matter can refer to any substance which interacts predominantly via gravity with visible matter (e.g., stars and planets).
A brief lesson on the gravitational effects of dark matter.Learn about Fritz Zwicky and his inference of the existence of dark matter.A discussion of gravitational lenses and the detection of dark matter in galaxies.Gravitational lens, as observed by the Hubble Space Telescope.In this picture a galactic cluster, about five billion light-years away, produces a tremendous gravitational field that “bends” light around it. Hypothetical form of matter comprising most of the matter in the universeDark matter aggregation and dense dark matter objectsDark matter aggregation and dense dark matter objectsSince dark energy does not count as matter, this is A small portion of dark matter could be baryonic and / or Some details of Zwicky's calculation and of more modern values are given in The details are technical.
