Some articles on asymptotically flat, flat:

Mass In General Relativity - Types of Mass in General Relativity - ADM and Bondi Masses in Asymptotically Flat Space-times
... the geometry of the space-time will tend to approach the flat Minkowski geometry of special relativity at infinity ... Such space-times are known as "asymptotically flat" space-times ... For systems in which space-time is asymptotically flat, the ADM and Bondi energy, momentum, and mass can be defined ...
Absolute Horizon - Definition
... An absolute horizon is only defined in an asymptotically flat spacetime — a spacetime which approaches flat space as one moves far away from any massive bodies ... Examples of asymptotically flat spacetimes include Schwarzschild and Kerr black holes ... — which is believed to be a good model for our universe — is generally not asymptotically flat ...

Famous quotes containing the word flat:

    We say justly that the weak person is flat, for, like all flat substances, he does not stand in the direction of his strength, that is, on his edge, but affords a convenient surface to put upon. He slides all the way through life.... But the brave man is a perfect sphere, which cannot fall on its flat side and is equally strong every way.
    Henry David Thoreau (1817–1862)
