Café Scientifique - Waves of Gravity, what it's like to work on a scientific breakthrough
A century ago, Albert Einstein predicted the existence of gravitational
waves as part of his general theory of relativity. He himself was sceptical
about their existence and it has taken 50 years of concerted effort to finally
prove they really do exist.
Justin Greenhalgh has spent his career working in
the field of project engineering at Rutherford Appleton Laboratory, including
several years working on equipment designed to detect gravitational waves. In
this talk he will outline how the UK became involved in the international
effort to detect the elusive waves, where they come from, why it was so hard to
do, how we did it in the end, and why it matters.
