Israelis find ‘marker’ for Einstein’s gravitational waves

New Worlds: Scientists are still searching for the small ripples in the fabric of space-time considered to be the "sounds" of the universe.

Nearly a century after Albert Einstein wrote about gravitational waves – small ripples in the fabric of space-time considered to be the “sounds” of the universe – scientists are still searching for them. Advanced gravitational wave detectors are being built in the US, Europe, Japan and Australia, and are scheduled to become operational in 2015. But the task is daunting; there are competing sources of “noise” that make it difficult to establish the source of any wave detected.
As a result, astronomers have for a long time been seeking a potential electromagnetic “marker” signal appearing with or after some gravitational waves. Such a marker would make it possible to verify the connection between detected gravitational waves and specific astronomical events….
