Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

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 ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

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 November, Quanta magazine published a feature on the detection of “magic” top quarks at CERN’s Large Hadron Collider (LHC). This magic, they explained, is part of an interesting shift happening at ...
