#:This is about the observations by the "BICEP2" telescope early in 2014.  The claim was that analysis of the polarization of the [[Cosmic microwave background]] (CMB) would show that the CMB had been influenced by gravitational waves in the first fraction of a second after the big bang.  That is, if noise from interstellar dust grains didn't confound the measurements.  It is now believed that the dust grain noise is too high to make this a reliable measurement.

#:Please read the cited article.  It indicates that, based on observations by the Planck satellite, it should be possible to make a cleaner observation.  The balloon-borne "Spider" telescope is slated to be launced later this year, and it might be successful.

#:Taking the failure of the BICEP2 observations as a counterexample to relativity is like saying "I thought of a new and clever proof of the existence of God last week, but unfortunately there was a flaw in my logic, so therefore God doesn't exist."

#:In any case, another indirect observation of gravitational waves has already been made, in the Hulse-Taylor observations of binary pulsar [[PSR B1913 16]] in the 1990's.
