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 ...

A new approach to solving the mystery of dark energy (Update)

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.

Bilayer graphene inspires two-universe cosmological model

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical measurements. ...
