Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

If one drops a marble and a bowling ball from the 44th floor of a high-rise in Manhattan, they would fall at the same time. The same principle holds true even for all objects regardless of their mass, ...

Galileo’s most famous experiment has taken a trip to outer space. The result? Einstein was right yet again. The experiment confirms a tenet of Einstein’s theory of gravity with greater precision than ...

The most precise test yet of one of Albert Einstein’s ideas about gravity has once again shown he was right. The finding means that physicists may need experiments that are even more accurate to ...

Artistic representation of the implemented photonic experiment in which entanglement between the polarizations of single photons is mediated by the independent degree of freedom of the photon path.

Get ready for a lesson in physics as Rick Crosslin, also known as The Science Guy, brings his latest experiment, the “Drop of Doom,” to life. Known for making science accessible and exciting, Crosslin ...

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...
