Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

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 ...

In a continuous pursuit to understand the fundamental laws that govern the universe, researchers have ventured deep into the realms of string theory, loop quantum gravity, and quantum geometry. These ...

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 ...

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 ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).
