Top Five Dark Matter Candidates

Authors: George Rajna

What if the universe we know is just one runty part of a larger, mostly invisible universe, and the only way we can interact is via gravity? [28] University of Houston scientists are helping to develop a technology that could hold the key to unraveling one of the great mysteries of science: what constitutes dark matter? [27] This week, scientists from around the world who gathered at the University of California, Los Angeles, at the Dark Matter 2018 Symposium learned of new results in the search for evidence of the elusive material in Weakly Interacting Massive Particles (WIMPs) by the DarkSide-50 detector. [26] If they exist, axions, among the candidates for dark matter particles, could interact with the matter comprising the universe, but at a much weaker extent than previously theorized. New, rigorous constraints on the properties of axions have been proposed by an international team of scientists. [25] The intensive, worldwide search for dark matter, the missing mass in the universe, has so far failed to find an abundance of dark, massive stars or scads of strange new weakly interacting particles, but a new candidate is slowly gaining followers and observational support. [24] “We invoke a different theory, the self-interacting dark matter model or SIDM, to show that dark matter self-interactions thermalize the inner halo, which ties ordinary dark matter and dark matter distributions together so that they behave like a collective unit.” [23] Technology proposed 30 years ago to search for dark matter is finally seeing the light. [22] They're looking for dark matter—the stuff that theoretically makes up a quarter of our universe. [21] Results from its first run indicate that XENON1T is the most sensitive dark matter detector on Earth. [20]
