These robust observations combine If dark matter is indeed a WIMP, it would interact so feebly with regular matter that we would have been able to detect it only with the generation of dark matter experiments that are just now coming on stream. Baryonic matter can, in principle, be detected through the electromagnetic radiation it releases. The measurements reported in this Letter, done at . Filaments between interacting clusters", published in the journal Astronomy & Astrophysics. After interaction of the unknown state with one part of the entangled pair, enough information can be obtained to put the other part of the pair into the initially unknown state. When matter and According to MIT's Samuel Ting, a physicist and the Alpha Magnetic Spectrometer's principle investigator, the first results will be published in two weeks, and “it won't be a minor discovery”; the paper has so far passed 30 revisions and is finally set for publishing. Every seconds, billions pass enables us to detect them. Some physics theories suggest that dark matter is made of WIMPS (weakly interacting massive particles), a class of particles that are their own antimatter partner particles. (Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning' immediately preceding a flash of ordinary lightning. Or are they completely dependent on one another's existence - like matter and gravity? The European Space Agency is planning on launching the Atmospheric Space Interactions Monitor (ASIM) within the next three years, which will be able to better detect both dark and visible lightning from space, said Řstgaard .. However, the first measurements by IMB and Kamiokande detected fewer muon neutrinos than expected, by a factor of about 2, and it seemed that the atmospheric neutrinos were worth studying in their own right. IceCube uses huge columns of very pure water buried below the ice-sheet in Antarctica to shield the neutrino detectors from the background radiation and cosmic rays. The reason they took so long to detect is that they do not interact very much with matter. This standard model of cosmology is supported by a lot of data, including the pervasive radiation field of the universe, the distribution of galaxies in the sky, and colliding clusters of galaxies. But there's a problem: the amounts of baryonic matter detected via Much of this tenuous, filamentary gas remains undetected, but astronomers expect that it could most likely be found between interacting galaxy clusters, where the filaments are compressed and heated up, making them easier to spot. They have no electrical charge, As a consequence of how little neutrinos interact with matter, they can pass through the Earth essentially unimpeded.
