Document Summary
Invisible dark matter makes up a significant amount of the universe, yet there are not a lot of technological methods to detect it. Recently research aims to use a powerful detector in the ambition to discover cold dark matter axions in the halo of the milky way galaxy (university of. Very minimal is actually known about axions, besides the fact that it appears to react gravitationally to matter, but otherwise it seems to have no other interaction. The axion was initially inferred by physicists in the 1970s to solve the problem in a theory called quantum chromo-dynamics (university of washington, 2013). Researches hypothesize that there must be some invisible but massive substance, like a gravitational glue, that averts rotating of galaxies from spinning apart. Axions being a candidate that potentially are the makeup of cold dark matter that would act as this glue (university of washington, 2013).
