A ripple in the space-time continuumIn one of the great astronomical discoveries scientists today said they made direct observation of gravitational waves -- ripples in space-time foretold by Albert Einstein 100 years ago. Physicists said the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes – that were about 29 and 36 times the mass of the sun, to produce a single, more massive spinning black hole.
