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

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 ...

Appearance is one thing, but reality is another. The world does not appear to be a hologram, but maybe it is. Thus begins physicist Leonard Susskind in opening a doorway between science and religion ...

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 ...

For most of the past century, wormholes sat comfortably in the realm of science fiction, a mathematical curiosity that let ...

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

It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid, forming swirling vortex lines and stable rotating ...

In a study by TU Wien and FU Berlin, researchers have measured what happens when quantum physical information is lost. This clarifies important connections between thermodynamics, information theory ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

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 ...
