The Search for Dark Matter

This film, from Twig World, looks at the work of scientists, deep underground in a disused mine in Yorkshire, searching for particles that can't be seen and have never been detected, but might bind our Universe together.

The key points made in the film are:

•Dark matter is believed to make up about 85% of the mass of the Universe

•Dark matter particles interact very rarely with other matter, making them hard to identify

•Experiments designed to detect dark matter are conducted underground, where there is less interference from cosmic rays

•The Boulby Underground Laboratory is located in North Yorkshire, in an old potash mine over 1000m deep
