In general relativity, a **fluid solution** is an exact solution of the Einstein field equation in which the gravitational field is produced entirely by the mass, momentum, and stress density of a fluid.

In astrophysics, fluid solutions are often employed as **stellar models**. (It might help to think of a perfect gas as a special case of a perfect fluid.) In cosmology, fluid solutions are often used as cosmological models.

### Famous quotes containing the words solution and/or fluid:

“To the questions of the officiously meddling police Falter replied absently and tersely; but, when he finally grew tired of this pestering, he pointed out that, having accidentally solved “the riddle of the universe,” he had yielded to artful exhortation and shared that *solution* with his inquisitive interlocutor, whereupon the latter had died of astonishment.”

—Vladimir Nabokov (1899–1977)

“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)
