Dark Matter Hunters: a Quantum View of the Invisible Universe

Dark matter, which makes up 85% of the matter in the Universe, remains one of the greatest mysteries in physics. A team of scientists are using ground-breaking developments in quantum technology to hunt for hypothetical dark matter particles in new ways. This film is based on research by the QSHS & QUEST-DMC consortiums.

The World's Coolest LEGO Set!

A world leading team of ultra-low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator. This machine - specially made at the University - is the most effective refrigerator in the world, capable of reaching 1.6 millidegrees above absolute zero (minus 273.15 Centigrade), which is about 200,000 times colder than room temperature and 2,000 times colder than deep space.
