Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

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 ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden contraction and then bounced into the expanding universe we know today is not ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Over the past 50 years, astronomers have made dozens of major discoveries that help explain the nature and origins of the universe. They’ve measured the cosmic microwave background, or leftover ...

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 ...
