Cosmology and General Relativity
According to the theory
of general relativity, gravity is caused by
the curvature of space-time.
The effects of gravity
on the largest cosmological scales should be related to the curvature of
space-time!
The curvature of
space-time, in turn, is determined by the distribution of
mass and energy in the universe.
Space-time tells matter how to move;
matter tells space-time how to curve.
