In a new study published in Classical and Quantum Gravity, researchers have revisited the concept of Einstein-Rosen bridges, the theoretical structures often associated with wormholes. This study, ...

Something like 13.8 billion years ago, all energy in the universe was condensed into a single point. Until suddenly it wasn’t. The resulting detonation was the most massive explosion in all of the ...

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 ...

Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 ...

A glowing loop of X-rays as wide as 20 light years across has been found near the centre of the Milky Way. It may represent a new source of mysterious charged particles called cosmic rays, say ...
