The most popular idea of Dark Matter we have, is that is made of WIMPs, or Weakly Interacting Massive Particles. Yesterday, researchers working with the Cryogenic Dark Matter Search (CDMS) announced a possible detection of three dark matter particles. They intend the principle for forward contamination issues. 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. 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. If these really do exist, there would be millions passing through us every second. Much evidence has been accumulated to support the existence of dark matter, which, unlike normal matter, does not give off or absorb electromagnetic radiation. It's also known that some micro-organisms can use perchlorates as a source for energy, and that some micro-organisms are astonishingly resistant to UV radiation. 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. 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. 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. It also used to All this rather suggests that the search for a sample on Mars with unambiguous signs of fossil or present day life may be a long one, that can only be carried out by taking life detection equipment to the surface.
