Generations of researchers have tried to create a quantum theory of gravity, and their work has produced sophisticated ...

“How quantum mechanics and gravity fit together is one of the most important outstanding problems in physics,” Kathryn Zurek, ...

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.

New study proposes using atomic clocks to probe the intersection of quantum mechanics and general relativity in spacetime.

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

What happens if you keep stacking neutrons until gravity itself takes control? Neutrons, the silent stabilizers inside atomic nuclei, seem perfect for building matter since they don’t repel like ...

Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity, on the other hand, describes how gravity shapes the universe through the bending of space and time.

"Understanding quantum gravity is one of the last major frontiers of physics," the researchers stated. "PNaSs offer a unique opportunity to observe phenomena that are otherwise inaccessible in ...

The interplay between quantum corrections and gravitational interactions not only challenges current paradigms but also paves the way for novel experimental approaches to probe Planck-scale physics.

Have you ever wondered what would happen if you tried to build an object made entirely of neutrons? Imagine a neutron tennis ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...
