Gravitational Waves Discovered! Here's What You Need To Know

Scientists have turned up rare evidence that space-time is smooth as Einstein predicted, while pushing closer to a complete theory of gravity. From NASA Goddard Space Flight Center, Fermi Gamma.

The very first gravitational wave has been detected by LIGO, proving Albert Einstein's Theory of Relativity! Where did it come from and what does it mean for the future of space science?.

Einstein predicted gravity waves in his general theory of relativity, but to date these ripples in the fabric of space-time have never been observed. What are gravitational waves? We know.
