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.

Another near-term application is the quantum gravity gradiometer being developed by the NASA Jet Propulsion Laboratory and NASA Goddard Space Flight Center.

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast ...

(via PBS Space Time) The vacuum of space is a chaotic sea of quantum fluctuations. Some have said that this vacuum energy can be harvested to build our future starship engines, or manipulated to build ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Quantum-gravity theories attempt to unite gravity and quantum mechanics. A proposed tabletop experiment called Gravity from the Quantum Entanglement of Space Time (GQuEST) would search for a predicted ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of scientists: how to reconcile the physics of the very big with the physics of the ...
