Written by: However, they can still be indirectly detected through their interaction with matter around their boundaries. 4 out of 5 dentists recommend this WordPress.com site. 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. Astronomers have observed stars in other galaxies orbiting particularly bright regions containing highly concentrated gas and emitting unusually large amounts of radiation. For example, gas and dust around a black hole emit X-rays as they spiral inwards. 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). How Big Are the Largest Black Holes and How Do Astronomers Detect Them? 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. Presumably a similar principle applies to weakly-interacting dark matter particles. The measurements reported in this Letter, done at . Essentially, the interactions and collisions within the accretion disk convert the momentum energy of the orbiting matter into radiation. Principles Of Radiation Interaction In Matter And Detection.
