Dynamical dark energy might explain strange 21-cm signal

Dark energy may evolve in time, and it may even connect through a new force of nature with dark matter. A researcher believes that we may have already seen evidence for this. Their findings have been reported on the preprint ...

Experiments see first evidence of a rare Higgs boson decay

The discovery of the Higgs boson at CERN's Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently investigating the properties ...

Curved spacetime in a quantum simulator

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such ...
