2008 is a landmark year in science: it's when the Large Hadron Collider - the biggest, most complicated machine ever built - switches on. This machine is so powerful that it can make a tiny and fleeting recreation of what the universe looked like a billionth of a second after the Big Bang. Scientists hope that studying what happens will help them understand some of the universe's biggest mysteries – from why we live in a world made of matter, not antimatter, to what most of the mass in the universe is made of.

DrTara Shears, a particle physicist from the University of Liverpool, and film-maker Alom Shaha, want to share with everyone the thrill of this inspirational, high tech journey into the unknown, so they have made some films about it for the BBC Big Screen network. Each of the five films aims to convey one big idea in under four minutes and in a visually striking way. They hope that they help demonstrate why the Large Hadron Collider is such an amazing experiment, and why this is such an exciting time in science.

The films will also be showing on BBC Big Screens in 17 cities across the UK. Go to www.bbc.co.uk/bigscreens to find your nearest screen.
