Seeking gravitational waves in space

2 December 2015 Last updated at 17:48 GMT

The most exquisite space physics experiment yet devised in Europe goes into orbit on Thursday.

Lisa Pathfinder will test technologies for a future mission to detect gravitational waves.

These are ripples in the fabric of space-time that are produced when black holes collide and stars explode.

Some of Lisa Pathfinder's instrumentation was produced at Glasgow University by Dr Harry Ward and his team.
