5. Dr. Janna Levin — Gravitational Waves, Black Holes and the Nature of the Cosmos

On Thursday, February 11, 2016, the National Science Foundation made a thrilling announcement: gravitational waves—first predicted by Einstein as part of his general theory of relativity in 1916—had been detected for the first time. This incredible development made front page news and was reported by outlets across the country. How was such a remarkable discovery, a long hundred years after Einstein's prediction, made possible?

In this Science Salon based on her new book, Black Hole Blues and Other Songs from Outer Space, astrophysicist and award-winning writer Dr. Janna Levin tells the epic story of the scientific campaign to record these waves—the holy grail of modern cosmology. A handful of physicists, led by Kip Thorne and Ronald Drever at Caltech and Rainer Weiss at MIT, have been working nearly their entire careers to conceive of, design, and build an instrument sensitive enough to detect gravitational waves. Levin delves into the lives and fates of the scientists, painting compelling portraits of these very human visionaries. She journeys from Los Angeles to Boston, to the LIGO interferometers in Hanford, Washington and Livingston, Louisiana, to the labs, offices, and observatories where the work in this great quest has painstakingly unfolded over the past five decades. Her account of the personalities, surprises, setbacks, and successes is a compelling and intimate portrait of the people and processes of modern science.
