A new study published in Physical Review Letters explores the possibility that a strongly supercooled, first-order phase transition in the early universe could explain gravitational wave signals ...
Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...
Scientists have long known that most of the matter in the universe is invisible. This hidden material, called dark matter, ...
Dark matter has been thought to be cold and collisionless, meaning its particles don't interact with each other. The new study, however, challenges this assumption.
A new study led by researchers at the University of California, Riverside, suggests that ...
