Among her fellow astronomers, Vera Rubin is known as an expertobserver of the night sky, one of the best. Her reputation derives from theproject she has doggedly pursued through most of her career: measuring how 【M1】______fast spiral galaxies are spinning, from their luminous cores out of the faint 【M2】______wisps of light at their fringes. Such a task may sound tedious; even hercolleagues thought so when she started the project 20 years ago. But for her 【M3】______painstaking measurements Rubin has' learned something important aboutgalaxies: they spin so fast they have to fly apart. Since galaxies do not seem【M4】______to be shedding stars the way like a rotating lawn sprinkler shed water; 【M5】______moreover, something must be holding the stars in. That something has to be 【M6】______gravity, no other force is powerful enough on a galactic scale. And where 【M7】______there is gravity, there is mass. Rubin realized that a huge reservoir of extramaterials, invisible to her telescope, must be tucked away somewhere in each 【M8】______galaxy. We cannot see this matte--it is invisible to all our detectors. Butthis 'dark matter' seems to make up at least 90 percent of the mass of theuniverse.Large because of Rubin's work, dark matter has become the buzzword in 【M9】______Astronomy. Her work has stirred such ferment that observers are desperate to 【M10】______find some way of seeing dark matter and theorists are desperate to find anexplanation of what it is--swarms of unknown elementary particles, forinstance, hidden armadas of Jupiter-like planets.【M1】
