Abstract

The uncertainties concerning LIGO's alleged discovery of the gravitational wave GW150914 (PRL 116, 061102 (2016)) have not been removed during the past year. The calibration e-print arXiv:1602.03838v1 [gr-qc] 11 Feb 2016 was not published in a peer reviewed journal, and is not listed among the RG contributions of two prominent co-autthors: Prof. B. Allen and Prof. K. Danzmann, directors at the German Einstein-Institut. Without published experimental evidence of LIGO's ability to measure 10^(-18) m displacement of heavy mirrors in relation to 4 km interferometer arm length (hairbreadth in relation to 4 lightyears) one cannot claim a 'discovery'. The Nobel committee is surely aware of these facts.
Second Open Letter to the Nobel Committee for Physics

Dear Professor Mårtensson,
you are certainly aware of the Open Letter to the Nobel Committee for Physics 2016:
https://www.researchgate.net/publication/304581873_Open_Letter_to_the_Nobel_Committee
_for_Physics_2016. Unfortunately, the uncertainties concerning the LIGO experiment have
not been removed during the past year. On the contrary, neither an event of similar magnitude
as GW150914 was detected, nor was the calibration paper arXiv:1602.03838v1 [gr-qc] 11
Feb 2016 published in a peer reviewed journal. The co-authors Prof. Bruce Allen and Prof.
Karsten Danzmann do not even list this e-print among their publications in ResearchGate,
although this report was cited in reference [63] of PRL 116, 061102 (2016) as an integral part
of the ‘discovery’. There is no doubt, without proving experimentally LIGO’s ability to
measure 10 oscillations of heavy mirrors with an amplitude of one thousandth of a proton
radius within 200 milliseconds as allegedly induced by GW150914 one cannot claim any
discovery.
Nevertheless, some authors of the ‘discovery paper’ PRL 116, 061102 (2016) express in the
media their expectation that LIGO must be awarded a Nobel Prize in 2017. I am sure, your
Committee will not comply with these unfounded and unreasonable requests until a solid
experimental proof of a real discovery of the hypothetical gravitational waves has been
published.
Yours sincerely,
Wolfgang Engelhardt
