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

Hunting spacetime fluctuations could unite Einstein and quantum physics By Michael Irving December 05, 2023 An artistic impression of an experiment investigating whether spacetime follows classical or ...

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 ...

The idea that the universe itself might be intelligent sounds like science fiction, yet a growing group of researchers is treating it as a serious scientific question. Instead of seeing consciousness ...

The elusive Higgs particle has the power to undo physics as we know it. The fact that it hasn't could have big implications about the nature of the universe. When you purchase through links on our ...

Could the observable universe be exclusively composed of layered, mutually entangled systems? The passage of time puzzles quantum physicists, who seek to fit it into a cohesive model. One wild theory ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow life, and especially conscious life, to arise. When you purchase through ...

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 ...
