  2. Dark matter - Wikipedia

    en.wikipedia.org/wiki/Dark_matter

    Dark matter can be divided into cold, warm, and hot categories. [116] These categories refer to velocity rather than an actual temperature, indicating how far corresponding objects moved due to random motions in the early universe, before they slowed due to cosmic expansion – this is an important distance called the free streaming length (FSL ...

  3. Direct detection of dark matter - Wikipedia

    en.wikipedia.org/.../Direct_detection_of_dark_matter

    Direct detection of dark matter is the science of attempting to directly measure dark matter collisions in Earth-based experiments. Modern astrophysical measurements, such as from the Cosmic Microwave Background , strongly indicate that 85% of the matter content of the universe is unaccounted for. [ 1 ]

    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 ...

  5. Large Underground Xenon experiment - Wikipedia

    en.wikipedia.org/wiki/Large_Underground_Xenon...

    The Large Underground Xenon experiment (LUX) aimed to directly detect weakly interacting massive particle (WIMP) dark matter interactions with ordinary matter on Earth. . Despite the wealth of (gravitational) evidence supporting the existence of non-baryonic dark matter in the Universe, [1] dark matter particles in our galaxy have never been directly detected in an expe

  6. Light dark matter - Wikipedia

    en.wikipedia.org/wiki/Light_dark_matter

    Dark matter production occurs predominantly when the temperature of the plasma falls under the mass of the dark matter particle itself. This is in contrast to the thermal freeze out theory, in which the initial abundance of dark matter was large, and differentiation into lighter particles decreases and eventually stops as the temperature of the ...

  7. DarkSide (dark matter experiment) - Wikipedia

    en.wikipedia.org/wiki/DarkSide_(dark_matter...

    The DarkSide collaboration is an international affiliation of universities and labs seeking to directly detect dark matter in the form of weakly interacting massive particles (WIMPs). The collaboration is planning, building and operating a series of liquid argon time projection chambers (TPCs) that are employed at the Gran Sasso National ...

  8. Indirect detection of dark matter - Wikipedia

    en.wikipedia.org/wiki/Indirect_detection_of_dark...

    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 ...

  9. LZ experiment - Wikipedia

    en.wikipedia.org/wiki/LZ_experiment

    The LUX-ZEPLIN (LZ) Experiment is a next-generation dark matter direct detection experiment hoping to observe weakly interacting massive particles (WIMP) scatters on nuclei. [1] It was formed in 2012 by combining the LUX and ZEPLIN groups. It is currently a collaboration of 30 institutes in the US, UK, Portugal and South Korea.
