How theoretical physics changed the world

You don’t have to be a scientist to get excited about breakthroughs in theoretical physics. Discoveries such as gravitational waves and the Higgs boson can inspire wonder at the complex beauty of the universe no matter how little you really understand them

Gravitational waves found: the inside story

One hundred years ago, Albert Einstein, in his general theory of relativity, predicted the existence of a dark side to the cosmos. He thought there were invisible “gravitational waves”, ripples in space-time produced by some of the most violent events in the

A giant leap for theoretical physics

Scientists working at the LIGO experiment in the US have for the first time detected elusive ripples in the fabric of space and time known as gravitational waves. There is no doubt that the finding is one of the most ground-breaking

Physicists prove ‘quantum spookiness’

The world of quantum mechanics is weird. Objects that are far apart can influence each other in what Albert Einstein called “spooky action at a distance”, and cats can potentially be dead and alive at the same time. For decades, scientists have tried to prove that these effects are not just
