Our first glimpses into the physics that exist near the center of a black hole are being made possible using 'loop quantum gravity'-- a theory that uses quantum mechanics to extend gravitational ...

"Physicists like to probe the extreme,” said Garrett Goon, a physicist at Carnegie Mellon University. “The fact that you can’t go further, that something is changing, something is blocking ...

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 ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

Can we ever know what happened before the Big Bang? It may have been only a stage in the existence of our Universe rather than its beginning, but analysis suggests the Big Bang is a barrier beyond ...

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).

Quantum gravity is an attempt to reconcile two theories of physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Quantum gravity is an attempt ...
