Oz girl solves mystery of universe’s missing mass
MELBOURNE: Astrophysicists have for long baffled with the universe’s "missing mass" puzzle . Now, an Australian student claims to have finally cracked the scientific conundrum.
Physicists knew that universe contained more mass than was visible in planets, stars and other objects — but didn’t know where to find it. They estimated about half the mass required to keep the universe functioning as it does was "missing" . Now, 22-year-old Amelia Fraser-McKelvie , an aerospace engineering student has discovered the missing material.
She conducted a targeted Xray search of vast structures known as "filaments of galaxies" . Her analysis of material confirmed that mass was present in the filaments. "If we’re looking 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 called the missing mass problem . People have theorized that this mass has settled in filaments that extend between galaxies , so we tested & confirmed this prediction," she said.
