Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

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 ...

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

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.

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.

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 ...

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

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 ...

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

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...
