Horizon: The Mystery of Dark Energy

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up

The effects of dark energy were discovered in 1998, but physicists still don’t know what it is. Worse, its very existence calls into question Albert Einstein‘s general theory of relativity – the cornerstone of modern physics.

The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge – someone who can write a new theory explaining the … Ler mais

Marcus du Sautoy: Faster Than the Speed of Light?

Professor Marcus du Sautoy explores claims that scientists at CERN have detected particles which seem to travel faster than the speed of light

In September 2011, an international group of scientists has made an astonishing claim – they have detected particles that seemed to travel faster than the speed of light. It was a claim that contradicted more than a hundred years of scientific orthodoxy. Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes.

So what is going on? Has Einstein‘s famous theory of relativity finally met its match? Will we one day … Ler mais

The Ultimate Formula

For over a century, physicists have searched for a blueprint of the universe in the form of a single mathematical formula

The great mysteries of the universe have long fascinated humankind, and for physicists, the answer to everything lies in the “ultimate formula”. Throughout history, scientists like Newton and Einstein have believed that all natural phenomena can be explained by a single formula. And now, with the discovery of the Higgs boson, the ultimate formula is almost within our grasp. Exploring the frontier of human knowledge, we look at the story of the brilliant physicists and their indefatigable efforts to … Ler mais

Einstein’s Quantum Riddle

Join scientists as they grab light from across the universe to prove quantum entanglement is real

Over the past century, scientists have made huge strides in understanding the mind-bending rules that govern the microworld of atoms and subatomic particles. But these rules, called quantum mechanics, contain one particularly bizarre, unexplained phenomenon: quantum entanglement.

Imagine two subatomic particles that mirror changes in each other instantaneously over any distance – apparently without communicating. Einstein called it “spooky action at a distance” and although no one can explain how it works, scientists have already begun to harness … Ler mais

Inside Einstein’s Mind: The Enigma of Space and Time

The story of the most elegant and powerful theory in science, Albert Einstein's general relativity. It takes us inside the head of Einstein to witness how his idea evolved.

The story of the most elegant and powerful theory in science – Albert Einstein’s general relativity.

When Einstein presented his formidable theory in November 1915, it turned our understanding of gravity, space and time completely on its head. Over the last 100 years, general relativity has enabled us to trace the origins of the universe to the Big Bang and to appreciate the enormous power of black holes.

To mark the 100th anniversary of general relativity, this film … Ler mais

Scotland’s Einstein: James Clerk Maxwell – The Man Who Changed the World

Documentary in which Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein's hero and inspiration – James Clerk Maxwell

Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein‘s hero – James Clerk Maxwell. Maxwell’s discoveries not only inspired Einstein, but they helped shape our modern world – allowing the development of radio, TV, mobile phones and much more.

Despite this, he is largely unknown in his native land of Scotland. Scientist Iain Stewart sets out to change that, and to celebrate the life, work and legacy of the man dubbed ‘Scotland’s forgotten Einstein’.… Ler mais

Terá Einstein errado?

O grande acelerador de partículas LHC (Large Hadron Collider ou Grande Colisionador de Hadrões) é uma das experiências científicas mais avançadas, construído para “esmagar” protões a uma velocidade avassaladora e recriar momentos após o Big Bang, mas infelizmente não funciona e, segundo o ‘paper’ (trabalho realizado) por um académico de North East, existe a intrigante possibilidade de não ser por falha técnica, mas porque a teoria básica da física estar errada.

Peter Hayes diz que “físicos teóricos agarraram-se a um … Ler mais
