A varying density is referred to as

curvature of space.

The

curvature of space can distort the CMB's "hot" and "cold" spots, changing their apparent size.

Since there are major drawbacks to the curvature of space model of gravity maybe gravity is just a superposition of moving standing waves produced by presently undefined ultimate structures of matter.

Again intuitively curvature of space time has nothing to do with inertia and momentum.

A separate theory and different equations present this fundamental force as a consequence of the

curvature of space and time (SN: 12/3/94, p.

This possibility arises from an effort to integrate quantum theory, which applies to the behavior of matter on a microscopic scale, with the general theory of relativity, which holds that gravity is a geometric effect dependent on the

curvature of space.

What success these theorists may have hinges on the formidable task of solving the equations underlying the general theory of relativity, The equations describe a physical force, gravity, in terms of geometry-variations in the

curvature of space and time.

In Einstein's theory, the force of gravity is a manifestation of the

curvature of space and time caused by the warping effects of concentrations of masS.

Clusters of galaxies in the foreground act as gravitational lenses, distorting the

curvature of space to produce multiple images of any background feature.

In 1916 Albert Einstein published his general relativity theory, which attributes gravitational forces to changes in the

curvature of space from point to point.

Einstein's general theory of relativity makes an essential connection among the force of gravity, the

curvature of space and accelerated motions.

After Einstein had made time into a geometrical dimension, he proceeded to make gravitational forces identical with a geometric quality, the

curvature of space.
