The questions in this quiz are suitable for GCSE physics students studying gravitational fields, weight, mass and gravitational field strength, how to calculate work done, free body diagrams and ...

Two recent developments suggest how familiar properties of gravity and matter may emerge from the quantum geometry that underlies loop quantum gravity. In everyday situations, and even in current high ...

Some clusters of galaxies may not need dark matter in order for their physics to work. In new research, a physicist describes a “shell singularity,” where gravity applies without mass. Today’s ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...

Virtual particles may not be real, but they help physicists track how forces move, and allow for incredibly precise ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...
