Breakthrough: Scientists detect Einstein-predicted ripples

WASHINGTON (AP) — In an announcement that electrified the world of astronomy, scientists said Thursday that they have finally detected gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago.
Some scientists likened the breakthrough to the moment Galileo took up a telescope to look at the planets.
The discovery of these waves, created by violent collisions in the universe, excites astronomers because it opens the door to a new way of observing the
