Search for dark matter from the center of the Earth with ten …
2024年12月18日 · The nature of dark matter remains unresolved in fundamental physics. Weakly Interacting Massive Particles (WIMPs), which could explain the nature of dark matter, can be captured by celestial bodies like the Sun or Earth, leading to enhanced self-annihilation into Standard Model particles including neutrinos detectable by neutrino telescopes such as the IceCube Neutrino Observatory. This ...
[2412.13131] Constraints on Strongly-Interacting Dark Matter …
2024年12月18日 · Direct-detection searches for dark matter are insensitive to dark matter particles that have large interactions with ordinary matter, which are stopped in the atmosphere or the Earth's crust before reaching terrestrial detectors. We use ``dark'' calibration images taken with the HgCdTe detectors in the Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) to derive ...
NASA’s Roman to Search for Signs of Dark Matter Clumps
2024年1月17日 · Some of the finest, smallest details in the universe – the gaps between elongated groups of stars – may soon help astronomers reveal dark matter in greater detail than ever before. After NASA’s Nancy Grace Roman Space Telescope launches, by May 2027, researchers will use its images to explore what exists between looping tendrils of stars that are pulled from globular clusters.
Dark matter - Wikipedia
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.
Searching for dark matter inside the Earth - Phys.org
2021年7月30日 · Despite decades of astronomical evidence for its existence, no one has yet been able to find any sign of it closer to home. There have been dozens of efforts to do so, and one of the most prominent...
Dark matter | Definition, Discovery, Distribution, & Facts - Britannica
2024年12月18日 · dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
What Is Dark Matter? | NASA Space Place – NASA Science for Kids
2024年12月5日 · Dark matter is stuff in space that has gravity, but it is invisible and isn’t like anything else we know about. Dark matter makes up about 27% of the universe. Dark energy makes up roughly 68% of the universe.
Dark Matter - Science@NASA
We call this substance dark matter, an invisible form of matter that doesn’t emit, absorb or reflect light, or interact with normal matter. It’s theorized to make up 85 percent of the universe’s total mass, or almost 30 percent of the universe’s combined mass-energy.
Dark Matter & Dark Energy - Science@NASA
Discover the universe's building blocks – matter, dark matter, and dark energy. Everything scientists can observe in the universe, from people to planets, is made of matter. Matter is defined as any substance that has mass and occupies space. But there’s more to the universe than the matter we can see.
IceCube Just Spent 10 Years Searching for Dark Matter
2024年12月20日 · Any dark matter trapped inside Earth, would release neutrinos that IceCube could detect. To date, and with 10 years of searching, it seems no excess neutrinos coming from Earth have been found!
