The theoretical framework underlying gravitational waves may have to be revamped to account for dark energy and the acceleration of the expansion of the universe. That’s the conclusion of researchers ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

Dark energy is one of the greatest mysteries in modern physics, comprising nearly 70% of the universe and causing its ...

Churning nano-wormholes could explain the clash in our cosmological constants. The wormholes add magnitude to a math parameter called the Gauss-Bonnet term. Boosting one term in a complex equation ...

Those of you who know my writing will know that I don’t use many analogies. Analogies have a very useful place in helping people understand difficult concepts, but they also have a tendency to be a ...

Einstein's self-proclaimed "biggest blunder" -- his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) -- may not be such a blunder after all, ...
