A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality. New ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane ...

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).

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...
