Zeroing In On Dark Matter: “A Complete Mystery That Lies Beyond the Standard Model of Particle Physics”
In the search for the mysterious dark matter, physicists have used elaborate computer calculations to come up with an outline of the particles of this unknown form of matter. To do this, the scientists extended the successful Standard Model of particle physics which allowed them, among other things, to predict the mass of so-called axions, promising candidates for dark matter.
Evidence for the existence of this form of matter comes, among other things, from the astrophysical observation of galaxies, which rotate far too rapidly to be held together only by the gravitational pull of the visible matter.
The scientists expect that it will be possible within the next few years to either confirm or rule out the existence of axions experimentally.
