Gravitational waves that are 'sounds of the universe'

Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe.

Does Gravity Explain Physics' Mysteries? | IdeaFeed | Big Think | Science News | Scoop.it

A new theory about gravity has been put forth that could tie the loose ends of contemporary physics. Edmund Schluessel of Cardiff University says that large waves of gravity which disrupt the space-time grid could still be rippling through the universe billions of years after the big bang set them in motion. Those ripples could be strong but subtle enough to warp our observations of the universe while simultaneously keeping us from detecting the waves directly. If the waves affect the refraction of light, many of our current observations could be thrown into doubt.
