"For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos."
NASA scientist Dr. John Cannizzo discusses black holes in the universe, beginning with a historical perspective and concluding with a discussion of recent direct detection by LIGO of gravitational waves emitted by two merging black holes.
