Don LincolnSummary: Dark matter is the conjectured substance that outweighs ordinary matter by five to one. However, we can't see it, nor can anyone say what it is -- at least, not yet. The first clues to the existence of dark matter was in observations of stars and galaxies in the 1930s. Since then, the evidence has mounted. Consider alternative explanations and reasons to believe that dark matter is indeed real.
