Can anyone understand this stuff?
https://fulguritics.blogspot.com/2018/06/gw170817-occurs-at-green-bar.html
Ground magnetometers also registered an exceptional strongly-coupled magnetosphere-driven event with complex coherence, such as in this plot from the Brandon station in Southern Manitoba; geomagnetic field, Z-component, for a LIGO-encompassing ground station array selected for five stations on August 17, 2017 UTC, with GW event indicated:
Bay St. Louis, MS magnetometer (approx 120 km from Livingston, LA) presents the strongest Z-component peak at the trigger time for GW170817. The GW170817-L1 signal was the most distinctive signal for the LIGO-Virgo array, but a profound "glitch" corresponded with the point of greatest band coherence directly preceding peak SNR.

2007, Oklahoma: supercell storm phase generating longest lightning discharge path length recorded (321 km), from radar image rotated 18°from orthogonal coordinates. Both of these storms share spatial frequency scaling. The 183 km maximal bilateral spatial eigenmode [approx the radius of the reconstructed black hole source specified in LIGO publications of 175-186 km] is also the maximum 2D energy density dimension of each of the dual oscillatory cells of the Oklahoma GW150914-coincident thunderstorm.
A colored noise floor structure inextricably-linked to the upchirped ELF broadband transient known as GW150914 is composed of instrumentally waveguided resonant broadband TEM and TE-TM modes evolving relativistically from magnetic coupling at subluminal velocities at LIGO-specified spin rates for pre- and post-merger phases. This range is 0.57-0.75 c for GW150914. All three storms and discharge regimes are potentiated through critical, self-organizing quasiperiodic stability and share a similar location, but developed years apart; storms with these properties are sprite-producing and are almost always strongly coupled to ionospheric driving by the magnetosphere. These storms are also strongly-bound to location (carbonate aquifer boundaries with petroleum deposits), drifting very little over the course of hours and showing strong domain-bound rotational and cyclical behavior. As GW170817 strain data record, at the very least, local attenuation of an amplified magnetic transient (deriving from a similar strong magnetospheric-ionospheric coupling regime with time symmetry breaking, which is evident also for the six other LIGO high-confidence events that are generally accepted as astrophysical), some models from data scaled using Bayesian-generated approximations will preserve eigenmodes, modulation, and "jitter" from unwanted coherent electromagnetic components fundamentally affecting wavelet envelopes and template fits.
Interpretations of poorly filtered signal through naively-subtracted noise lead from prior experimental probabilities resting on the degree of confidence in former interpretation of prior high-confidence signals. In this sense, scale invariance can mask enhanced noise at LIGO calibration reference Q-factors, but is treated without attention to its dynamic sources in LIGO analysis. For GW170817, LIGO-Virgo data were very weak, affected by a glitch at Livingston, and non-existent for Virgo; Livingston is closest to the active storm over Texas overlapping shortest inter-detector length between detectors, and of ground magnetometer datasets utilized for coincident signal identification, Bay St. Louis has the strongest Z response.

GW170817 was most strongly sensed at Livingston, LA, but affected by an exceptional glitch (merely subtracted ad hoc). The first spectrogram below is constructed after application of extensive filtering and wavelet transforms, with bands <16 Hz truncated; the second plot shows multiple weak divergent synchronized chirp-like transverse modes and other threshold continuous signals in the same data (expected with respect to magnetospheric conditions underway), transected by a DC-saturating band-coherent separatrix glitch, folding at ~1024 Hz and time-correlated with GW signal. The glitch can be traced in strain data minutes prior to initial 24 Hz in bands <10 Hz. The minute-scaled, evolving GW170817 trigger was found to be significant above noise at 24 Hz, with low Q. Several Schumann magnetic modes are excited during this period, with ~60 Hz Schumann mode prominently double-peaked, as are upper harmonics, indicating that the origin of the broadband separatrix glitch artifact may be natural, with instrumental cavity artifacts and signal feedback. The folding frequency peak of the Schumann-correlated glitch is related to the 30-2048 LIGO sensitive range, a cavity f_1/2 subharmonic. Airy dislocation in Kerr media can generate chirp-like solitons.

Considering there is serious discussion about possible variable star activity perhaps being conflated with a GW170817 source (Texas Sharpshooter Fallacy), and as kilonova evolution models are unexpectedly failing the more we inject expectation into the empirical GW170817 portrait - its outcome seemingly hanging from a cliff by a finger at the margins of residual distributions - we should probably stop pretending to be convinced that we even understand what happened on August 17, 2017 UTC.
It is also important to note a failure to detect expected neutrino emission, explained away by the supposed off-axis orientation of the initial relativistic jet responsible for the GRB170817A trigger: No neutrino emission from a binary neutron star merger

Lack of neutrinos proves that GWs exist.
https://icecube.wisc.edu/news/view/539
Today, the LIGO and Virgo collaborations have announced the detection of a new gravitational wave event, GW170817, which constitutes the first time that a binary neutron star merger has been detected with the LIGO observatory. This unique observation is even more compelling since the same collision was seen by the Fermi and INTEGRAL satellites as a result of a short gamma-ray burst (GRB) and, subsequently, across the electromagnetic spectrum, with radio, optical, and X-ray detections. These observations made it possible for the first time to pinpoint the source location of a gravitational wave event. The source was found to be in a galaxy 130 million light years away, known as NGC 4993.
In a joint effort by the ANTARES, IceCube, Pierre Auger, LIGO, and Virgo collaborations, scientists have searched for neutrino emission from this merger. The search looked for neutrinos in the GeV to EeV energy range and did not find any neutrino in directional coincidence with the host galaxy.
The nondetection agrees well with our expectation from short GRB models of observations at a large off-axis angle
, which is most likely the case for the GRB detected in conjunction with GW170817. These results have just been submitted to The Astrophysical Journal.
Localizations and sensitive sky areas at the time of the GW event in equatorial coordinates: GW 90% credible-level localization (red contour), direction of NGC4993 (black plus symbol), directions of IceCube’s and Antares’s neutrino candidates within 500 s of the merger (green crosses and blue diamonds, respectively), Antares’s horizon separating down-going (north of horizon) and up-going (south of horizon) neutrino directions (dashed-blue line), and Auger’s fields of view for Earth-skimming (darker blue) and down-going (lighter blue) directions. IceCube’s up-going and down-going directions are on the northern and southern hemispheres, respectively. The zenith angle of the source at the time of the merger was 73.8° for Antares, 66.6° for IceCube, and 91.9° for Auger.

The detection of a gravitational wave event is always exciting news for astrophysicists, but having one also confirmed for the first time by other instruments that detect photons is even more exciting. It marks the beginning of a new era of multimessenger astrophysics. For IceCube scientists, it is another step toward the time when cosmic events will be detected and studied with neutrinos, light, and gravitational waves together.
The combined gravitational wave and gamma-ray observation of this event tells us that there was particle acceleration by the source, which provides insight into the merger process and also means that
very high energy neutrinos might have been produced.
The detection of neutrinos would reveal even more information about the merger, including the density and energy of the hadrons involved and the energy dissipation mechanisms.
The search for neutrino emission from this collision of two neutron stars has been conducted in collaboration with both the ANTARES and Pierre Auger observatories, which bring improved sensitivities at different energies. At the exact time of the merger, the source could fortuitously be seen from an ideal viewing angle by the Pierre Auger observatory. For IceCube and ANTARES,
the direction to the source was in a part of the sky where the detectors are less sensitive, but still capable of making significant observations.
The first study concentrated on a time window within
500 seconds
around the detection of GW170817, and yielded no associated neutrino events. Later, scientists expanded the search to include possible emission of high-energy neutrinos
up to 14 days after the merger
, suggested by theoretical predictions, and also searched for lower energy neutrinos associated with the merger remnant and ejected material. These follow-up studies did not find any significant emission either.
The lack of neutrino emission from GW170817 is in good agreement with the observation of a GRB from a high viewing angle, i.e., with the outflow jet not pointing toward Earth.
IceCube has already proven the existence of an extragalactic flux of astrophysical neutrinos and has searched jointly with ANTARES for neutrino emission from other gravitational wave sources, e.g., binary black holes GW150914 or GW151226. With a growing network of gravitational-wave detectors, it is expected that many more binary neutron star mergers will be discovered in the near future, expanding the capability to study these sources through high-energy neutrinos with IceCube and through findings from joint studies with other neutrino telescopes.

From wikileaks....
https://en.wikipedia.org/wiki/GW170817
GW170817 was a gravitational wave (GW) signal observed by the LIGO and Virgo detectors on 17 August 2017. The GW was produced by the last minutes of two neutron stars spiralling closer to each other and finally merging, and is the first GW observation which has been confirmed by non-gravitational means.[1][2] Unlike the five previous GW detections, which were of merging black holes not expected to produce a detectable electromagnetic signal,[3][4][5][a] the aftermath of this merger was also seen by 70 observatories on seven continents and in space, across the electromagnetic spectrum, marking a significant breakthrough for multi-messenger astronomy.[1][7][8][9][10] The discovery and subsequent observations of GW170817 were given the Breakthrough of the Year award for 2017 by the journal Science.[11][12]
The gravitational wave signal, designated GW170817, had a duration of approximately 100 seconds, and shows the characteristics in intensity and frequency expected of the inspiral of two neutron stars. Analysis of the slight variation in arrival time of the GW at the three detector locations (two LIGO and one Virgo) yielded an approximate angular direction to the source. Independently,
a short (~ 2 seconds duration) gamma-ray burst, designated GRB 170817A, was detected by the Fermi and INTEGRAL spacecraft beginning 1.7 seconds after the GW merger signal
.[1][13][14] These detectors have very limited directional sensitivity, but indicated a large area of the sky which overlapped the gravitational wave position. It has long been theorized that short gamma-ray bursts are caused by neutron star mergers.
An intense observing campaign then took place to search for the expected emission at optical wavelengths. An astronomical transient designated AT 2017gfo (originally, SSS17a) was found, 11 hours after the gravitational wave signal, in the galaxy NGC 4993[15] during a search of the region indicated by the GW detection. It was observed by numerous telescopes, from radio to X-ray wavelengths, over the following days and weeks, and was shown to be a fast-moving, rapidly-cooling cloud of neutron-rich material, as expected of debris ejected from a neutron-star merger.
In October 2018, astronomers reported that GRB 150101B, a gamma-ray burst event detected in 2015, may be analogous to GW170817. The similarities between the two events, in terms of gamma ray, optical and x-ray emissions, as well as to the nature of the associated host galaxies, are considered "striking", and this remarkable resemblance suggests the two separate and independent events may both be the result of the merger of neutron stars, and both may be a hitherto-unknown class of kilonova transients. Kilonova events, therefore, may be more diverse and common in the universe than previously understood, according to the researchers.[16][17][18][19]

So, here is what they say-said.
The merger was 130 million lightyears away.
Gravity waves travel at exactly 1.000c & are not slowed by anything (when inside mass, or near mass).
Gamma rays potentially travel at c, but traveled slower, arriving 1.7 sec later than the LIGO GW event, the slowing being due to (1) slowing inside plasma & (2) slowing due to nearness of mass (due to being in a gravity field).
Neutrinos travel slower than c, arriving up to 14 days later in theory, because neutrinos are particles & travel slower than c.
The silly sausages have it mostly wrong. Here is what i read or reckon.
GWs dont exist, but any kind of change in gravity must travel at at least 20 billion c (Van Flandern)(not 1.000 c).
Neutrinos are created by the joining of two photons, the two sets of fields cancelling.
Hencely being photonic neutrinos potentially probly travel at 1.000 c (as for gamma rays), & are slowed in plasma & when near mass similarly to gamma rays but less so (because of zero nett em field).
Hencely neutrinos should be detected before gamma rays, say 1.6 seconds before.
Hencely neutrinos could have been detected inside their 500 sec window, but they were not detected.
They said that that was (1) because of a highly concentrated direction of emission during the merger which unfortunately did not encompass Earth & (2) because of the limited directional detection capabilities on Earth resulting in the detector being slightly blind in some directions. Was that a lie?
(1) does make sense (within their silly GW theory). If GWs were emitted in the plane of the binary orbit then it makes sense that neutrinos might be emitted mostly axially, ie orthogonal to the orbital plane. We know that pulsars emit photonic radiation mostly axially along their spin axis. Praps neutrinos are likewize emitted axially (here we are now talking about the axis of the binary orbit). In the case of vizible photons there might be an electromagnetic reason. Neutrinos have zero nett em fields & one could reason that their emission would be less likely to be strongly axial.
Wait, i have changed my mind. Gamma rays were detected. If neutrinos are emitted mostly axially then it makes sense that gamma rays are axial too (even moreso than neutrinos u would think). In which case their excuse (1) has a bad stink.
Here is what wikileaks had to say......
No neutrinos consistent with the source were found in follow-up searches by the IceCube and ANTARES neutrino observatories and the Pierre Auger Observatory.[2][1] A possible explanation for the non-detection of neutrinos is because the event was observed at a large off-axis angle and thus the outflow jet was not directed towards Earth.[37][38]
Anyhow a lack of neutrinos raises the following questions-matters.....
(a) Violent mergers dont make neutrinos (nope, ignore this one).
(b) There was no merger.
(c) The detected GWs came from a different kind of cosmic source, (d) a source that doesnt produce neutrinos.
(e) The GWs were not GWs, they were faux-GWs.
(f) Terrestrial lightning might produce faux-GWs (& lightning produces gamma rays)(gamma rays were detected 1.7 sec later than the faux-GWs)(here the 1.7 sec delay doesnt have a good explanation)(i will have a think).
