Gravitational Waves Can Explain Dark Energy And Axis of Evil, Says Cosmologist - Technology Review: Until now, cosmologists have considered only waves with relatively short wavelengths. But Schluessel's idea is to imagine what the universe would look like if it contained much bigger waves with a wavelength of the order of the curvature of the cosmos itself, that's some 10^10 light years. These would be waves left over from the big bang that continue to resonate slowly on a vast scale
Here's the thing. Schluessel says these waves would distort the microwave back ground radiation in way that matches the preferred directions cosmologists see today. What's more, it would also distort the light from distant objects in way that would make them look as if they were accelerating away.
