The hunt for gravitational waves could be nearing success

Physicists are growing confident of detecting ephemeral ripples in the universe, and they are gearing up to engage the public in the discovery

Here's a date for your diary: 1 January 2017. It's the day that physicists are predicting for a great scientific breakthrough: the first direct detection of gravitational waves.

Even if you have not yet heard about gravitational waves, you are going to in the coming years. When they are detected, it will revolutionise our investigation of the universe.
