Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

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 ...

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 ...
