The mass-to-light ratios correspond to dark matter densities predicted by other large-scale structure measurements. The 1997 DAMA/NaI experiment and its successor DAMA/LIBRA in 2013, claimed to directly detect dark matter particles passing through the Earth, but many researchers remain skeptical, as negative results from similar experiments seem incompatible with the DAMA results. Ice (D.Gray-Man) producing sub-zero temperature flames that freezes anything they "burn" from his Dark Matter. Because intuitively, you will try to make light to fight it, right? In the world of anime/manga, Dark Matter has broad range of powers, including Form Manipulation/Elemental Manipulation. A postulated candidate is the sterile neutrino: A heavier, slower form of neutrino that does not interact through the weak force, unlike other neutrinos. Have any problems using the site? In a redshift map, galaxies in front of a supercluster have excess radial velocities towards it and have redshifts slightly higher than their distance would imply, while galaxies behind the supercluster have redshifts slightly low for their distance. [115], The possibility that atom-sized primordial black holes account for a significant fraction of dark matter was ruled out by measurements of positron and electron fluxes outside the Sun's heliosphere by the Voyager1 spacecraft. [179][180], A problem with alternative hypotheses is that observational evidence for dark matter comes from so many independent approaches (see the "observational evidence" section above). This claim is so far unconfirmed and in contradiction with negative results from other experiments such as LUX, SuperCDMS[143] and XENON100.[144]. However the detected fluxes were too low and did not have the expected energy spectrum, suggesting that tiny primordial black holes are not widespread enough to account for dark matter. Opposite to Nether Manipulation. Because no one has directly observed dark matter yet assuming it exists it must barely interact with ordinary baryonic matter and radiation except through gravity. [17] In the appendices of the book 'Baltimore lectures on molecular dynamics and the wave theory of light' where the main text was based on a series of lectures given in 1884,[18] Lord Kelvin discussed the potential number of stars around the sun from the observed velocity dispersion of the stars near the sun, assuming that the sun was 20 to 100 million years old. As a result, its density perturbations are washed out and unable to condense into structure. The most widely accepted hypothesis on the form for dark matter is that it is composed of weakly interacting massive particles that interact only through gravity and the weak force. Directional dark matter experiments include DMTPC, DRIFT, Newage and MIMAC. Advanced Umbrakinesis practitioners can actually cause entire cities or countries to fall into total darkness, just using the power of their mind. Instead, they may be matter or energy of varying properties, depending on the manufacturing process, such as being outside the boundaries of the laws of physics, or granting abilities and even bodies. The resulting gravitational potential acts as an attractive potential well for ordinary matter collapsing later, speeding up the structure formation process.
