Title: Upper Limits on a Stochastic Background of Gravitational Waves
Authors: LIGO Scientific Collaboration: B. Abbott, et al
Comments: 6 pages, 4 figures

The Laser Interferometer Gravitational Wave Observatory (LIGO) has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three different spectral power laws. For the flat spectrum, our limit of Omega_0<8.4e-4 in the 69-156 Hz band is ~10^5 times lower than the previous result in this frequency range.

Still nothing. So, what is expected?

Should we be worried yet?

There are still a few inches of diving board left i think.
