In pictures: Giant science experiment


Cern in Switzerland is the home of one of the biggest science experiments ever. It starts next year and will teach scientists loads about the universe.


This 18-mile long tunnel is a key part of the experiment. Newsround's cameraman is filming it for the programme.


And here's Lizo with another important part. Check out all this computing power. These scientists are experts, though - the internet was invented here!


These giant wheel-like pieces of equipment are detectors. There are eight of them in use in this experiment.


And this is how big they are, compared to Lizo! Each one is 25 metres across.
