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 ...
The second class are those which try to find voids via the geometrical structures in the dark matter distribution as suggested by the galaxies. [29] The third class is made of those finders which identify structures dynamically by using gravitationally unstable points in the distribution of dark matter. [ 30 ]
Most of the mass in the universe is made up of a kind of matter that none of us have ever seen. It's called "dark matter" and, despite being incredibly abundant, it's also extremely difficult to ...
The visible matter in the Universe, such as stars, adds up to less than 5 percent of the total mass that is known to exist from many other observations. The other 95 percent is dark, either dark matter, which is estimated at 20 percent of the Universe by weight, or dark energy, which makes up the balance. The exact nature of both still is unknown.
In April 2023, a study investigated four extremely redshifted objects discovered by the James Webb Space Telescope. [5] Their study suggested that three of these four, namely JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0, are consistent with being point sources, and further suggested that the only point sources which could exist in this time and be bright enough to be observed at these ...
Dark matter makes up most of the universe and decides how it grows – but still remains mostly mysterious
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:
About 90% of all matter appears to be dark matter, which has mass (or, equivalently, gravitational influence), but does not interact electromagnetically and, hence, cannot be observed directly. [140] There is no generally accepted description of this new kind of matter, within the framework of known particle physics [ 141 ] or otherwise. [ 142 ]
