Is it really noise or just more signal?
Cosmic background radiation is noise but it can be mapped out into a pattern. Could the correlation be a view of a type of cosmic background gravitational waves?
- dboreham 9y agoThe pattern is in a different dimension than the noise (time vs spatial). A pattern by definition isn't noise.
- kobeya 9y agoNot by definition. There is such a thing as structured noise.
- mirimir 9y agoWell, except: > The main claim of Jackson’s team is that there appears to be correlated noise in the detectors at the time of the gravitational-wave signal. This might mean that, at worst, the gravitational-wave signal might not have been a true signal at all, but just louder noise. If that's an accurate characterization, "louder noise" does seem a lot like signal. Couldn't the "correlated noise" just be a superposition of numerous small gravitational-wave signals?
