Gravitational waves: Why the fuss?
The physics world is abuzz ahead of a hotly anticipated announcement Thursday concerning the quest to track down gravitational waves. But what are they, and why should you care?
We consulted the experts.
Q: What are gravitational waves?
A: Albert Einstein predicted gravitational waves in his general theory of relativity a century ago. They are ripples in space-time, the very fabric of the Universe.
