On the Theory of Gravitational Wave Rumour Sources
There has been a great deal of excitement almost nowhere in the astrophysics community since it was announced recently that rumours of the detection of gravitational waves had yet again begun to circulate, so I thought I would add here a brief discussion of the theoretical background to these phenomena.
The standard theoretical model of such rumours is that they are produced from time to time during the lifetime of a supermassive science project after periods of relative quiescence. It is thought that they are associated with a perceived lack of publicity which might threaten funding and lead to financial collapse of the project. This stimulates a temporary emission of hype produced by vigorous gossip-mongering which acts to inflate the external profile of the project, resisting external pressures and restoring equilibrium. This general phenomenon is not restricted to gravitational wave detection, but also occurs across many other branches of Big Science, especially cosmology and particle physics.
However, observations of the latest outburst suggest support for a rival theory, in which rumours are produced not by the project itself but by some other body or bodies in orbit around it or even perhaps entirely independent of it. Although there is evidence in favour of this theory, it is relatively new and many questions remain to be answered. In particular it is not known what the effect of rumours produced in this way might be on the long-term evolution of the project or on the source itself.
