A theoretical study accepted by Physical Review Letters predicts that gravitational waves, the faint ripples in spacetime produced by colliding black holes and neutron stars, can leave detectable ...

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 ...

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 ...

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Physics is tough. Want to spot a ripple in space-time? You just need a detector capable of seeing a length change less than one-millionth the size of an atom. Want to find a Higgs boson? No problem – ...

Northwestern Engineering's Selim Shahriar won a 2025 NASA Innovative Advanced Concepts program award for his visionary idea to reconcile quantum mechanics with the theory of general relativity.

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...
