A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

While quantum phenomena can be demonstrated using experiments such as the Double-Slit Experiment, certifying that a multi-qubit system is truly tapping into quantum mechanics is a challenge. It also ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black hole singularity paradox. By modifying Einstein's theory of general ...

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 ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

Einstein was a great thinker who made plenty of mistakes—errors that sometimes led to more meaningful discoveries in physics, ...

Wormholes, conceptual tunnels slicing through spacetime, offer a theoretical shortcut between two distant cosmic points.

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Breakthrough from Princeton team reveals exotic quantum state that coherently blends many-body correlation and quantum topology—two key concepts of modern quantum physics in a single material.

It's a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced ...
