Cardiff Uni's role in gravitational waves breakthrough

Scientists at Cardiff University played a key role in one of the "biggest breakthroughs in physics for the last 100 years", BBC Wales can reveal.

Theoretical models developed by researchers were used to verify the detection of gravitational waves.

Predicted by Albert Einstein in his famous Theory of General Relativity, the tiny ripples in space-time offer a new way of exploring the Universe.
