Most of the #universe is made of something we cannot see. Scientists call it #DarkMatter, and it's believed to make up about 85 per cent of all matter in existence. #NTUsg scientists have taken a new step towards understanding it. They designed special crystals with magnetic properties that make light particles behave similarly to #axions, which are believed to form dark matter. By watching how light moves through these crystals like axions, scientists could eventually learn how to detect actual
