Wits Astronomy Day on Thursday, the 19th of April 2012, kicked-off with a lecture by Dr Bruce Elmegreen from the IBM Research Division in New York, US, in the Wits Great Hall.
School children, students, astronomers and the public attended the lunchtime lecture on Dark Matter where Elemgreen highlighted the instruments and experiments that have led to remarkable discoveries.
Elmegreen said though scientists know Dark Matter is there its presence has never been detected or felt. With new technologies and ways to “map” Dark Matter, scientists hope to make more sense of a matter that dominates much of the Universe.
