There are so many "chirps" of so many sources. How easy would it be for the LIGO system to
sense them directly or indirecly.
Chorus radio waves within earth's atmosphere is very similar to the long LIGO signal.
In the papers, I would expect signal/respond characteristics of all kinds of signals.
That is how you make a good detector. That why mobiles and such work very well.
But I have not seen any papers on them.
All needs to be tested before we can take the observations serious.
One major problem that I found is the resonating of ANY signal that the LIGO receives.
This is caused by the recycling of light at the laser-end.
It is much worse than anyone else here thinks:
Any signal repeats itself after bouncing between all mirrors.
And any changes in the length or time or phase of the light, changes this path due to the splitter.
So we get a amplitude modulated noise repeated over and over again, with "random" variations.
It is also their major source of noise, which can not be filtered away with their tricks.
Am I so smart? Or are the LIGO scientists so biased?
I think of the latter, which is common in a university environment.
Explanation of the resonating signal:
The light goes from the laser to the splitter. From there it goes bouncing forth and back through one of the arms between 2 mirrors at both ends of the arms with 4 km distance. This repeats 280 times.
(In the LIGO. Figure may change with upgrades)
(wiki: By the use of partially reflecting mirrors, Fabry–Pérot cavities are created in both arms that increase the effective path length of laser light in the arm. )
This gives an effective path of 1120 km.
From there it goes through the splitter and arrives at the receiver, which is a mirror.
Then it goes back to the splitter, through the other arm 4 k to the other mirror, bouncing forth and
back again for 1120 km.
And from there back to the laser.
At the laser, there is another mirror that recycles the light.
This means the signal is recycled after going 2240km.
This gives a base-resonance frequency of any noise and signal of 133.9 Hz.
This is inside their "signal" range.
It is similar to any echo.
Now there is another problem:
The splitter is a mirror that works differently when the phase of a signal changes.
So if the phase changes during the 2240 km,
the path of the signal can change too.
It can either take a longer path, or the shorter path.
So noise in the phase will cause frequency changes of the recycled signal.
In this case doubling and halving them. Sometimes multiple times.
This is what we actually see in the graphs provided by LIGO.
The noise is clearly in those frequency ranges.
While I have some theories, I still don't know how exactly
electromagnetism can affect the LIGO-system.
But it would be easy to do some tests for direct influences.
