It did bother me a bit that there was never any indication on the
poster that we haven't detected any gravitational waves. I'm
reluctant to post the poster without a disclaimer so that my
students won't assume the waves have been measured. Contrast this
with the publicity surrounding LHC and the Higgs particle ... it's
very clear that it hasn't been measured.
but the fact that the rotational frequency decay rate of several
carefully measured pulsars can be exactly accounted for by the
emission of gravitational energy (gravitons) is considered pretty
conclusive evidence of their existence by the community.
One must also recall that the existence of neutrinos was assumed to
be settled long before they were actually detected (otherwise, why
would it have taken 40 years before the feat was recognized by the
Nobel Committee?).
I do agree. however. that in the interests of full disclosure the
chart needs to be clear that the waveform graphs are theoretical, and
no "direct" detection of gravity waves has yet taken place--which
isn't to say that there remains any significant controversy over
their existence.
