While particle theories are currently the most favored explanations for dark mater, physicists have still been unable to detect dark matter particles in ways that would confirm or contradict these theories. Some theorists ...
All of the matter in the universe -- everything we see, feel and smell -- has a certain predictable structure, thanks to the tiny electrons spinning around their atomic nuclei in a series of concentric shells or atomic levels. ...
