This talk tells the story of symmetry in theoretical physics, and its interplay with developments in our understanding of gravity over the years. In this talk, McNamara explores the power of symmetry ...

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 ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

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, ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

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 ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

At the heart of flight lies Newton's third law: for every action, there is an equal and opposite reaction. This principle explains how an airplane wing generates lift. When an airplane moves forward, ...
