“The Vera Rubin Observatory will enable astronomers to map the distribution of dark matter like never before, based on how dark matter bends the path of ordinary starlight — a process known as ...
One mystery of dark matter is that it makes up the vast majority of all the matter in the Universe, yet we know surprisingly little about it. A new study, based on observations of distant galaxy ...
Dark matter: What is the identity and composition of dark matter? [31] Is dark matter a particle? If so, is it a WIMP, an axion, the lightest superpartner (LSP), or something else? Do the phenomena attributed to dark matter point to an extension of gravity instead of some other type of matter? Dark energy:
Dark matter may have played a role in the formation of the bars. The discovery also suggests that bars can be detected in early galaxies, despite the fact that the oldest galaxies are much smaller.
A MAssive Compact Halo Object (MACHO) is a kind of astronomical body that might explain the apparent presence of dark matter in galactic halos. A MACHO is a body that emits little or no radiation and drifts through interstellar space unassociated with any planetary system (and may or may not be composed of normal baryonic matter). Since MACHOs ...
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.
Searches for the products of dark matter interactions are profitable because there is an extensive amount of dark matter present in the universe, and presumably, a lot of dark matter interactions and products of those interactions (which are the focus of indirect detection searches); and many currently operational telescopes can be used to ...
This inconsistency is attributed to dark matter. [243] The rotation curve of the Milky Way agrees with the universal rotation curve of spiral galaxies, the best evidence for the existence of dark matter in galaxies. Alternatively, a minority of astronomers propose that a modification of the law of gravity may explain the observed rotation curve ...
