The student conducted a targeted X-ray search of vast structures known as "filaments of galaxies", which stretch across the vast expanse of space. Examining data the research team had already gathered, her analysis of material confirmed that mass was present in the filaments.
"If we're looking very, very long distances from Earth we're detecting mass, but if we're looking closer to Earth we only see about half the mass that we're expecting to see. This is what is called the missing mass problem.
"People have theorised that this mass has settled in filaments that extend between clusters of galaxies, so we tested and confirmed this prediction by detecting it in the filaments," the Australian media quoted Amelia as saying.
Remember, ladies and gents, when you have to invent something as dumb as "dark matter" to describe your missing mass, you're not looking hard enough.
