Does a cosmic “glitch” in gravity challenge Albert Einstein's greatest theory?

There's no denying the tremendous predictive power of Albert Einstein's 1915 theory of gravitation and general relativity, however, the theory still suffers from inconsistencies when it comes to calculating its effect over vast distances. New research suggests that these discrepancies may be the result of a “cosmic imbalance” in gravity itself.

In the 109 years since it was first formulated, general relativity has remained the best description of galactic-scale gravity; Experiments have repeatedly confirmed its accuracy. This theory has also been used to predict aspects of the universe that would later be confirmed by observation. These include the Big Bang, the existence of black holes, gravitational lensing of light, and tiny ripples in spacetime called gravitational waves.
