Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

Peter Verheyen explores ongoing debates in quantum mechanics and the relationship between quantum information, consciousness ...

Physicists observed a quantum state change in ultracold atoms. This change matched Einstein's equivalence principle for a ...

Now, scientists in Israel and abroad have taken a new step toward understanding how they interact by directly measuring how gravity changes a quantum object as it falls. The findings could eventually ...

A team of German physicists has built a fully working version of quantum mechanics that uses only real numbers. Complex ...

This idea may help address the black hole information paradox, especially the problem that black holes seem to violate a key quantum mechanics rule. A lab experiment with entangled photons showed that ...

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics.John Clarke, ...

Legendary experiments in 'cat-turning' from the 1850s can teach us about will, control and goal-seeking behaviour Cats are ...

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means. Everyone has their favourite example of a ...
