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 ...

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

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...

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 ...

The earliest acoustic vibrations in the cosmos weren’t exactly sound – they travelled at half the speed of light and there was nobody around to hear them anyway. But Jim Baggott says from the first ...

Ultracold atoms sit at the heart of the quantum-technology revolution. India has built a strong and steadily growing presence ...

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 ...
