  It has recently been reported by Cresswell et al. [1] that correlations in
the noise surrounding the observed gravitational wave signals, GW150194,
GW151226, and GW170194 were found by the two LIGO detectors in Hanford and
Livingston with the same time delay as the signals themselves. This raised some
issues about the statistical reliability of the signals themselves, which led
to much discussion, the current view appearing to support the contention that
there is something unexplained that may be of genuine astrophysical interest
[2]. In this note, it is pointed out that a resolution of this puzzle may be
found in a proposal very recently put forward by the author [3], see also [4],
that what seems to be spuriously generated noise may in fact be gravitational
events caused by the decay of dark-matter particles (erebons) of mass around
10^-5g, the existence of such events being a clear implication of the
cosmological scheme of conformal cyclic cosmology, or CCC [5], [6]. A brief
outline of the salient points of CCC is provided here, especially with regard
to its prediction of erebons and their impulsive gravitational signals.
