Dark Matter and Energy: An Overview and Possible Solution
... Doctors Silverman and Mallett have proposed that the dark matter and energy problems might be solved by postulating the existence of a scalar field that only interacts gravitationally and whose self-interaction is described by a Ginzburg-Landau potential density. Such a field would lose its symme ...
