on Feb. 11, 2016 the LIGO-team published the paper PRL 116, 061102 (2016): Observation of Gravitational Waves from a Binary Black Hole Merger. The experimental proof for the existence of a gravitational wave was announced: Mirrors of 40 kg had been displaced by 10-18 m during fractions of a second as measured with a Michelson-interferometer with 4 km arm length resulting in a strain of 10-21. Scaling up these data by a factor of 1013 a relative accuracy must have been achieved by a hair’s breadth (10 microns) in relation to the distance to the next fixed star (4 light-years). This is by a factor of 1 Million better than the relative Mössbauer accuracy of 10-15 obtained so far. Indeed, Rudolf Mössbauer was awarded the Nobel Prize for physics in 1961 for this achievement
