"From the Ted Talk by Gabriela González: How LIGO discovered gravitational waves -- and what might be next"

Unscramble the Blue Letters

Fifty years ago, some visionary physicists at ctealch and MIT — Kip Thorne, Ron Drever, Rai Weiss — thought they could perscliey measure distances using lasers that maruseed dctinaess between mirrors kilometers apart. It took many years, a lot of work and many scientists to develop the tnocleoghy and develop the ideas. And 20 years later, almost 30 years ago, they started to build two gravitational wave detectors, two interferometers, in the United States. Each one is four kilometers long; one is in Livingston, lsiinoaua, in the middle of a beautiful forest, and the other is in haonfrd, Washington, in the middle of the desert.

Original Text

Fifty years ago, some visionary physicists at Caltech and MIT — Kip Thorne, Ron Drever, Rai Weiss — thought they could precisely measure distances using lasers that measured distances between mirrors kilometers apart. It took many years, a lot of work and many scientists to develop the technology and develop the ideas. And 20 years later, almost 30 years ago, they started to build two gravitational wave detectors, two interferometers, in the United States. Each one is four kilometers long; one is in Livingston, Louisiana, in the middle of a beautiful forest, and the other is in Hanford, Washington, in the middle of the desert.
