  2. Dark matter - Wikipedia

    en.wikipedia.org/wiki/Dark_matter

    It is dark matter composed of constituents with an FSL much smaller than a protogalaxy. This is the focus for dark matter research, as hot dark matter does not seem capable of supporting galaxy or galaxy cluster formation, and most particle candidates slowed early. The constituents of cold dark matter are unknown.

  3. Dark energy - Wikipedia

    en.wikipedia.org/wiki/Dark_energy

    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 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 ]

    Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...

    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 ...

    The third peak can be used to get information about the dark-matter density. [69] The locations of the peaks give important information about the nature of the primordial density perturbations. There are two fundamental types of density perturbations called adiabatic and isocurvature. A general density perturbation is a mixture of both, and ...
