A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

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 ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Researchers have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world. Gravity is no longer ...

A new study has been published that further complicates the argument that gravity could be explained using quantum entanglement. If true, this could further complicate efforts to explain how gravity ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While 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 ...

Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be quantum: meet the scientists hunting for gravity's elusive nature ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...
