Question

Quizplus · Accepted Answer

An open universe is one in which the density of matter or energy is not great enough to halt the expansion of the universe. In an open universe, the geometry of space is hyperbolic, meaning that it has negative curvature. This is in contrast to a closed universe, which has positive curvature, and a flat universe, which has zero curvature.
