Gamma rays are also produced in this scenarios. So there is complementarity in the two ways of looking at the cosmos with high-energy gamma and neutrinos. 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. 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 .. They're right to be cautious: several marginal observations of dark If a dark matter particle known as a WIMP (weakly interacting massive particle) hits a nucleus inside the crystal, it will set up a small vibration: a quantum sound wave known as a phonon. Or are they completely dependent on one another's existence - like matter and gravity? If these really do exist, there would be millions passing through us every second. The detection principle of neutrinos in Antares is based on a signature of the cherenkov light emitted by muons produced in CC interactions. The new research suggests this view may be oversimplified, arguing that a substantial minority of dark matter might in fact interact strongly, and could be detected in cosmic-ray observations. Much evidence has been accumulated to support the existence of dark matter, which, unlike normal matter, does not give off or absorb electromagnetic radiation. 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. The most popular idea of Dark Matter we have, is that is made of WIMPs, or Weakly Interacting Massive Particles. (Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning' immediately preceding a flash of ordinary lightning. Principles Of Radiation Interaction In Matter And Detection. Yesterday, researchers working with the Cryogenic Dark Matter Search (CDMS) announced a possible detection of three dark matter particles. They are expected to be produced in the interaction of high-energy nucleons with matter or radiation. 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.
