Dark fluid

Dark fluid is a theoretical concept in cosmology that attempts to unify dark energy and dark matter into a single framework. In traditional models of the universe, dark energy is associated with the accelerated expansion of the universe, while dark matter is thought to be responsible for the gravitational effects that cannot be accounted for by observable matter. The idea behind dark fluid is that instead of treating dark energy and dark matter as separate entities, they could be manifestations of a single underlying substance or field.
