Abstract
The study of gas clouds orbiting in the outer regions of spiral galaxies has revealed that their gravitational attraction is much larger than the stars alone can provide. Over the last twenty years, astronomers have been forced to postulate the presence of large quantities of ‘dark matter’ to explain their observations. They are still in the ‘dark’ as to its true nature.
