Dark matter is a giant question mark looming over our knowledge of the Universe. There is more dark matter in the Universe than visible matter, but it is extremely elusive; it does not reflect, absorb or emit light, making it invisible. Because of this, it is only known to exist via its gravitational effects on the visible Universe. A favored theory is that dark matter might be constituted of "supersymmetric" particles. Supersymmetry is a theory in which all particles in our Standard Model -- electrons, protons, neutrons, and so on -- have a more massive "supersymmetric" partner. While there has been no experimental confirmation for supersymmetry as yet, the theory would solve a few of the gaps in our current thinking. One of supersymmetry's proposed particles would be stable, electrically neutral, and only interact weakly with the common particles of the Standard Model -- all the properties required to explain dark matter.
