Abstract : The early history of modern physics have been full of problems fixed with un-orthodox yet brilliant solutions. From the Hydrogen electron orbit, black bodyradiation and the ultraviolet catastrophe, to the perihelion precession of Mercury.Quantum Mechanics and General Relativity not only solved these problems butthey opened the path to new observations and predictions about the Universe welive in and the introduction of new problems to be solved.One of the more modern problems we are facing today in physics is the largediscrepancy among measurements of the visible mass in the Universe and the pre-dictions of laws of gravity. An indisputable mass of evidence from different partsof observational cosmology is showing again and again that the observed lumi-nous mass in the Universe constitutes a tiny fraction of the matter that actuallyexists. The proposed solutions of this problem comes in two completely differentflavors. One proposed solution is that the laws of gravity are not the same in thelimit of tiny accelerations. Theories of modified gravitational dynamics proposea non-linear term in Newton law of gravity that becomes relevant at small accel-erations which in turn can explains the missing matter. The other solution to themissing matter is the introduction of new type of matter that does not interact withlight, making it invisible yet inferred to exist by its gravitational effect. The newmatter becomes a new elementary particle to be added to list of already knownelementary particles. While there are many candidates to this new elementaryparticle the favored one is called a WIMP or Weakly Interacting Massive Particle.
