Space Time Ripples and Einstein's Legacy

Headline news was made earlier this year when the detection of gravitational waves, caused by the collision of two black holes, was confirmed by the Laser Interferometer Gravitational-Wave Observatory (LIGO). And earlier this month, another ripple was detected! The observed ripples in the fabric of space-time validate a key prediction in Albert Einstein's theory of general relativity. One hundred years old, the theory continues to astonish scientists with how correct it is. LIGO’s discovery signals a new era of astronomy and a new way of understanding the warped side of the universe. Ira Flatow, Moderator Janna Levin Nergis Mavalvala Lisa Randall
