In astronomy and cosmology, the dark fluid theory attempt to explain dark matter and dark energy in a single framework, as suggested by cosmologist Alexandre Arbey in 2005.[1][2] The theory proposes that dark matter and dark energy are not separate physical phenomena, nor do they have separate origins, but that they are strongly linked together and can be considered as two facets of a single fluid. At galactic scales, the dark fluid behaves like dark matter, and at larger scales its behavior becomes similar to dark energy.
In 2018 astrophysicist Jamie Farnes proposed that a dark fluid with negative mass would have the properties required to explain both dark matter and dark energy.[3][4]
