Quantum gravity and cosmology represent a frontier in theoretical physics where the principles of quantum mechanics are integrated with the framework of general relativity. This synthesis is crucial ...

In what the team describes as the largest-scale probe of gravity to date, they found that the force weakens with distance ...

Cosmic viewer The Atacama Cosmology Telescope in Chile was used by the team to observe gravitational interactions between ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Scientists have tested gravity across some of the largest structures in the universe and ...

Scientists could be wrong about dark energy. But they’re right about gravity, a new study suggests. Dark energy, the mysterious phenomenon that causes the expansion of the cosmos to accelerate, is ...

Physicists at Brown University suggest that the universe’s topology could explain why the cosmological constant — the energy driving cosmic acceleration — is far smaller than quantum theory predicts.

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

Physicists have used the Atacama Cosmology Telescope to prove that gravity follows the rules of Newton and Einstein across light-years ...

Penn physicist Patricio Gallardo and collaborators tracked the speeds of distant galaxy clusters to test the strength of gravity across hundreds of millions of light-years. The verdict? Gravity neatly ...

Dejan Stojkovic is a theoretical physicist. As a cosmologist, he can speak to the media about a number of questions related to the nature of the universe, including theories about the origins and ...
