Dancing in the Dark – The End of Physics?

A look at dark matter and dark energy ahead of the Large Hadron Collider being switched on in March 2015, having been upgraded

Scientists genuinely don’t know what most of our universe is made of. The atoms we’re made from only make up four per cent. The rest is dark matter and dark energy (for ‘dark’, read ‘don’t know’). The Large Hadron Collider at CERN has been upgraded. When it’s switched on in March 2015, its collisions will have twice the energy they did before. The hope is that scientists will discover the identity of dark matter in the debris.

The stakes are … Ler mais

Inside CERN

Horizon documents an extraordinary story in particle physics, following CERN's scientists as they hunt for the elusive signals that would prove if there is a new particle

With exclusive behind-the-scenes access, Horizon follows the highs and lows of an extraordinary story in particle physics. In June 2015, teams at CERN started running the large hadron collider at the highest energy ever. Rumours quickly emerged that they were on the brink of a huge discovery. A mysterious bump in some data suggested a first glimpse of a brand new particle that could change our understanding of how the universe works.

A new particle could hint at extra dimensions … Ler mais

Brian Cox – The Big Bang Machine

Grande Colisionador de Hadrões (Acelerador de Partículas) do CERN

Professor Brian Cox visits Geneva to take a look around Cern’s Large Hadron Collider before this vast, 27km long machine is sealed off and a simulation experiment begins to try and create the conditions that existed just a billionth of a second after the Big Bang.

Cox joins the scientists who hope that the LHC will change our understanding of the early universe and solve some of its mysteries.

LHC – The Six Billion Dollar Experiment

Grande Colisionador de Hadrões (Acelerador de Partículas) do CERN

In the coming months the most complex scientific instrument ever built will be switched on. The Large Hadron Collider promises to recreate the conditions right after the Big Bang. By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe.

Within these first few moments the building blocks of the Universe were created. The search for these fundamental particles has occupied scientists for decades but there remains one particle that has stubbornly … Ler mais
