Subject: LIGO‘s false reading

By Davide Castelvecchi, Nature magazine on January 13, 2016

It was a pleasure to read your unbiased article. Thank you.

Respectfully, I would highlight some simple facts that confront the rumors about the “LIGO’s” detecting G waves.

Are LIGO physicists concerned about the rumors? Yes.
“González is a little miffed. “I am concerned about creating false expectations in the public and the media,” she says.

I would add that simple physical rules tell us they could not have detected anything like G waves:

One

“LIGO's detectors, at their current sensitivity could pick up only gravitational waves of frequencies well above 10 Hertz. So if they have picked up a signal, they would have captured the final stages of the drama, when the black holes circle more than 10 times per second, speeding up to several thousand times a second just before they merge.”

Assuming only the estimated lowest barrier of 10Hz, the wavelength would be ~3*10⁷ m or at 100 Hz ~3*10⁶ m, and the R of Earth is only ~6.3*10⁷ m.

Hulse and Taylor got a Nobel Prize in 1993 for finding a binary pulsar PSR B1913+16 at a distance of 21,000 ly (1.987*10²⁰ m) and calculated that the emitted gravitational wavelength was about 4.19 10¹² m at 71.7*10^-6 Hz.

If λ=c/f, then 2.9979245*10⁸ m/71.7*10^-6 Hz would result in λ as large as 4.19 10¹² m provided the waves have the same speed as the electromagnetic waves.

(That particular system has a period of 7.75 hours or a

frequency of 35.8 microhertz, and the gravity waves come off at double that, or 71.7 microhertz, for a wavelength of 4.19 10¹² m)

If the recording the LIGO claims has happened, we should have seen something in the sky not too far back in our time.

Two

If the distance is relatively close to Earth, say 21,000 ly, - as the Hulse and Taylor study teaches us - by the time the waves would reach the instruments on Earth, the energy carried by the wave would have only 1.677 *10^-73 kgm²/s² due to the spherical dissipation, i.e. the rule of 1/R.

We already had a debacle about the so-called FRAMEDRAGING experience that had costs $793 million, plus a few million supplied by privet donors, they gave to save the day by doctoring the result for years after NASA declared the result inconclusive, or in strait words, a failure.

Now are we facing an demise of another futile venture i.e. try to detect waves

whose wavelength may be billions of times larger than the diameter of Earth or even Earth’s orbit?

If we do the Math, it is obvious that the higher the frequency the lover is the wave length and visa versa.

Whether these waves are exists or not, we will still have to face the inherent problem of the countless sources of G waves in our observable Universe, for if they really exist they would create a “choppy see” of the space that would hide well the origin of any disturbances.

For the simple Math about this argument please see the attached calculations on the next page.
