Vacuum Solution (general Relativity)

Vacuum Solution (general Relativity)

In general relativity, a vacuum solution is a Lorentzian manifold whose Einstein tensor vanishes identically. According to the Einstein field equation, this means that the stress-energy tensor also vanishes identically, so that no matter or non-gravitational fields are present.

More generally, a vacuum region in a Lorentzian manifold is a region in which the Einstein tensor vanishes.

Famous quotes containing the words solution and/or vacuum:

    There’s one solution that ends all life’s problems.
    Chinese proverb.

    No, it wasn’t an accident, I didn’t say that. It was carefully planned, down to the tiniest mechanical and emotional detail. But it was a mistake. It was a beaut. In the end, somehow granted the time for examination, we shall find that our so-called civilization was gloriously destroyed by a handful of vacuum tubes and transistors. Probably faulty.
    John Paxton (1911–1985)
