November 2015 marks the centenary of the publication of one of the most important theories in physics: Albert Einstein’s General Theory of Relativity. On this month’s episode I chatted to Prof Mark Hannam and Dr Patrick Sutton. As part of the Gravitational Physics group here in Cardiff, Mark and Patrick try to understand the implications of General Relativity, and are leading the search for direct proof one of its last remaining predictions: gravitational waves.

On Wednesday 9th December Cardiff University is hosting an evening reception to celebrate the centenary, with free wine and soft drinks, and a selection of talks by Cardiff researchers. The event is free, but don’t forget to book tickets if you’d like to come along.

And if you want a quick introduction to General Relativity, the following video was produced for the Science and Technology Facilities Council:
