Spacetime geometry, and therefore gravity, emerges from quantum entanglement, analyses using tensor networks show.

Next to revolutionizing our understanding of space, time and matter, quantum gravity will likely also significantly advance other areas. The nature of time and its uni-directional arrow are puzzles ...

Quantum mechanics describes the fundamental forces as dynamic, while gravity is geometric and thus doesn’t fit into physics’ standard model.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. Now scientists have proposed a new quantum ...

Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum mechanics. These two theories have profoundly changed the way we think about space, time ...

Pesky quantum behaviors are getting us closer to figuring out quantum gravity.

Quantum physics and gravitational physics remain separate due to the vastly different scales of time and space that they refer to. Now, research may point to links between them.
