Let it be noted that the petitioner is
<http://www.crankwatch.com/wiki/index.php/Jocelyne_Lopez>, a Frenchwoman and
“physics layman” (Physiklaie) now “living in Germany”, who, according to
that reference, has been trolling “several German-speaking Web fora since
about 2003“, and whose “blog has been banned” repeatedly by service
providers due to “a lot of insults, denials, antisemitism, and severe
violations of personal rights in them”. See the reference for details.
(The Google Translate translation of that Web site from German into English
is, as usual, inadequate, but should be sufficient for the dedicated
English-speaking reader to tell where the motivation for that petition comes
from.)
Some of her ridiculous "physical" statements include these on light
(translated by me, emphasis by me):
“[…] Light does exist, but you could say that in only exists in very few
places in nature. Because *light is not created in the universe* [sic!],
light is only created in our eyes. Light does not exist outside
our eyes, or, IOW, light is invisible outside our eyes.
[…]
This shows, paradoxically, that light is mostly invisible. The photons
or impulses that *are created* by the innumerable light sources *in the
universe* [sic!] do move […] but we do not see their motion; their motion
is not perceptible and not observable by us, we only see the few [sic!]
that accidentally hit our retina and only let light be created in our
eyes. Without the existence of the retina of observers, the universe is
completely dark, there is no light there.”
As for the "petition" itself:
“[…] There are, however, very great doubts in the international scientific
community as to whether the measurement accuracy required to register
gravitational waves can be achieved at all by current measurement
techniques and technology: […]”
What does she dream of at night? Being a physics laywoman, how can she even
know about what the consensus in the “international scientific community” is
or what the “current measurement techniques and technology” are? There is
no evidence available (and she certainly does not provide any) that there
would be doubt among scientists that this precision can be achieved;
precisely *because* of the size of the detector that was *built* so that
this precision could be achieved, and the diligence involved in eliminating
other causes for the results.
“On 14th Sept. 2015, during a period of approx. 0.2 seconds, the LIGO
detectors are supposed to have registered a displacement of the 40 kg
mirror of the interferometer by 10^(-18) m due to the pressure of a
gravitational wave stemming from the fusion of two black holes at a
distance of 1.3 billion light years.”
From which we can clearly see that she has absolutely no clue what she is
talking about.
First of all, it was not that "the mirrors were displaced", but the 4 km
long arms of the detectors were shortened and lengthened; there are full
mirrors at the end of each arm and semipermeable mirrors where the arms are
crossing, to deflect the *laser light* into the detector unit.
It was not the "pressure" of a gravitational wave that "displaced mirrors",
but a gravitational wave is a propagating *spacetime distortion* that
*changes the length of objects when it passes through them*. As a result,
the laser light travels a longer or shorter distance than if the
gravitational wave would not pass through the experiment, and because light
is an *electromagnetic* *wave*, the pattern of interfering rays of laser
light changes. (And laser light created by commercially available lasers
can have wavelengths down to 157 nm = 1.57 × 10⁻⁷ m. Put simply, the
wavelength is the distance from one crest of a wave to the next one.)
*That* is what was observed, and since all other known phenomena to cause
that change could be excluded, the cause had to be a gravitational wave.
Further analysis then showed where the wave must have come from.
That LIGO consists of *two* detectors *several thousand kilometers apart*
(in Livingson, LA, and Hanford, CT) is an additional bonus, because that
allows one to see that the gravitational waves actually traveled (all at
the speed of light) from the source to one detector, through it, from it
to the other one, through that, and on in the universe.
