LIGO Scientists Settle Gravitational Wave Rumors

Laser Interferometer Gravitational-Wave Observatory, or LIGO, detected gravitational waves generated by a black hole collision. The event is seen in this still from a computer simulation.

On Thursday, scientists confirmed yet another aspect of Albert Einstein’s theory of gravity.

Rumors were correct, and researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced that they directly detected a gravitational wave, or a ripple in the fabric of space-time. LIGO’s twin detectors, in Louisiana and Washington state, use lasers to watch for these tiny stretches and squeezes of space-time. Einstein published his pioneering work predicting the existence of gravitational ripples a century ago. The timing of the LIGO breakthrough couldn’t be better.

Scientists from Caltech, MIT and the LIGO Scientific Collaboration gathered to deliver the news about their detection efforts at 10:30 a.m. EST from the National Press Club in Washington, D.C.

The finding represents one of the most significant scientific discoveries of the decade, and launches a new era in observational astronomy. Discover has the news covered from a variety of angles. Read the full story here:

    Yippee! Another one of those breakthroughs I’d hoped I’d live to see.

    So how powerful are they?

  • Observational_Point

    Now, away from all the excitement of it all, does this discovery mean those at LIGO will be made redundant and the experiment decommissioned …. job done?
