Does a cosmic ‘glitch’ in gravity pose a challenge to Albert Einstein’s greatest theory?

The awesome predictive power of Albert Einstein’s 1915 theory of gravity, general relativity, is undeniable – yet the theory still exhibits inconsistencies when it comes to calculating its effect at great distances. And new research suggests that these inconsistencies could be the result of a “cosmic glitch” in gravity itself.

In the 109 years since general relativity was first formulated, it remains our best description of gravity on a galactic scale; time and time again, experiments have confirmed its accuracy. This theory has also been used to predict aspects of the universe that would later be confirmed by observation. This includes the Big Bang, the existence of black holes, the gravitational lensing of light, and tiny ripples in spacetime called gravitational waves.
