Some of its properties could be defined already, we obviously couldn't see it, so it didn't interact with electromagnetic radiation (light would simply pass straight through it) but its main property was that it had mass. In recent years the Fermi Gamma-ray Space Telescope has detected a flux of gamma-rays from the centre of our galaxy and the Wilkinson Microwave Anisotropy Probe (WMAP) has revealed a "haze" that also seems to envelop the Milky Way's core. The most popular idea of Dark Matter we have, is that is made of WIMPs, or Weakly Interacting Massive Particles. 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. Instead of anti gravity, we can use but in case anyone in the future wonders WIMP stands for "weakly interacting MASSIVE particle". You cant see it, none of that particular universes light or any other radiation or forces can be used to detect its matter 'dark matter', but we know its thereits If quantum gravity is a property of space, all EM forces are also part of this reference system and we can control them by fluid dynamic principles. Usually, a direct detection experiment operates in an underground laboratory to shield it from cosmic radiation and reduce background. Dark matter, dark energy, dark money, dark markets, dark biomass, dark lexicon, dark genome: scientists seem to add dark to any influential phenomenon that is poorly understood and somehow obscured from direct perception. 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. If these really do exist, there would be millions passing through us every second. Presumably a similar principle applies to weakly-interacting dark matter particles. Principles Of Radiation Interaction In Matter And Detection. Although dark matter is thought to make up more than 80% of all matter in the universe, it does not interact with electromagnetic radiation and its existence has been inferred from its gravitational effects on visible matter. Begin to interact with each other and self-annihilate, producing a characteristic positron energy signature that the Alpha Magnetic Spectrometer 2, aboard the International Space Station, may have recently detected (see this AmericaSpace article). Of the universe , as some do, inferring the existence of stuff that cannot be detected by telescopes or antennae or the other ways in which we presently can interact with the great beyond outside our solar system, seems hardly remarkable. Here at Purdue, we are working on the XENON direct dark matter search. Or are they completely dependent on one another's existence - like matter and gravity? (Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning' immediately preceding a flash of ordinary lightning. Essentially, the interactions and collisions within the accretion disk convert the momentum energy of the orbiting matter into radiation. 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 Østgaard ..
