Boyarsky is on a quest to unravel the nature of one of the most mysterious phenomena in the Universe. The cosmos appears to consist for the larger part out of mass we cannot see. We have no idea where it comes from. Physicists call this ‘dark matter’. Sterile neutrinos are candidate building blocks of dark matter. However, it has never been proven that these hypothetical particles even exist at all.
