Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

The cosmological constant, originally introduced by Einstein as a measure of vacuum energy density, has re-emerged as a central challenge in understanding the observed accelerated expansion of the ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

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 ...
