In astronomy and cosmology, dark fluid is an alternative theory to both dark matter and dark energy and attempts to explain both phenomena in a single framework.
Dark fluid proposes that dark matter and dark energy are not separate physical phenomena as previously thought, nor do they have separate origins, but that they are linked together and are really specific sub-effects of new extended laws of gravity at very large scales. Other alternative theories of extended gravity, such as Modified Newtonian dynamics (MOND), also show up as specific sub-effects. Our current laws of gravity modeled on observations within the scales of the Earth and the Solar system might be insufficient to explain gravity at these larger scales.

Famous quotes containing the words dark and/or fluid:
“These are not dark days: these are great days—the greatest days our country has ever lived.”
—Winston Churchill (1874–1965)
“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
—Ralph Waldo Emerson (1803–1882)
