Another Twist in the Dark Matter Story
US researchers say we can rule out dark matter being responsible for mysterious electromagnetic signals previously observed from nearby galaxies.
There were high hopes these signals would provide hard evidence to help identify dark matter, but new work by a team from the University of Michigan (UM), Lawrence Berkeley National Laboratory and the University of California, Berkeley, suggests otherwise.
Dark matter can't be observed directly because it does not absorb, reflect or emit light, but we know it exists because of the effect it has on other matter. Physicists have suggested dark matter is a closely related cousin of the neutrino, called the sterile neutrino.
