In Search of the Dark Matter in the Universe
... How much of this mysterious dark mass is there in the universe? Where do we find it? What is its real nature? Will we be able to directly detect it, since it does not radiate light or particles? It demonstrates its presence only by its gravitational pull on visible matter. These are the questions wh ...

A light-year is a unit of length equal to the distance that light travels through space in 1 year. Because the sp ...
