Conrad Ranzan's latest papers (everyone here knows his DSSU website) reveal the cause of ultra high energy neutrinos & gamma rays etc (mentioned in Smith's article in that link). The answer is the mirror image of Ranzan's explanation of cosmic redshift (redshift is due to the stretching of photons as photons approach mass & then a 2nd dose as they depart).Cargo wrote:"It is imperative, however, to understand what is going on in the minds of theoretical physicists. It is assumption upon assumption, building theories on the backs of other theories that can provide no experimental evidence."
"At the center of M81 is a supermassive black hole that is about 70 million times more massive than the Sun."

Yes a plastic ruler. What many dont know is that LIGO is supposed to work because the 40 mm laser supposedly does not suffer length contraction due to the passing of a supposed GW, whereas the 4 km of distance tween hanging mirrors supposedly does. In effect this then involves a rigid laser (ruler) & a non-rigid 4km tween hanging mirrors.Sci-Phy wrote:They know exactly what they are doing. I'm pretty sure their salary is bigger than mine.
Of course the whole idea is extremely stupid. LIGO measuring distance in "spacetime" using light and light is affected by such spacetime according to GR. For me it looks like study of thermal expansion using plastic ruler.
LIGO interferometer has tremendous precision. The precision in fact is 10000 smaller than the size of proton or around 10^-19m! Such precision is ten orders smaller compare to the light wavelength. I doubted it is possible to get interferometer precision better than quater of wavelength. Atom thermal vibration is around 10^-11m.
Any concept of waves in empty space is nonsence. Wave without returning force is not possible. In the mass on the spring example the returning force is F=-kx. The kinetic energy is transferring to potential energy of the spring and the mass is slowing down. Imagine EM wave - the amplitude of E at some point is rising, rising.. then what? What exactly cause electric field to stop rising? There are nothing around, just empty space and field do not interact with field.

And the first sentence of the "answer";LIGO Caltech wrote:If a gravitational wave stretches the distance between the LIGO mirrors, doesn't it also stretch the wavelength of the laser light?
Which of course doesn't address the quesion at all. Why is the light travelling different distances in each arm? They admit it's affected but then go on to say the distances are different. They can only be different if the light is completely unaffected by the GW. It makes no logical sense. You might as well say they have a special piece of string unaffected by the expansion and contraction of space and time.LIGO Caltech wrote:While it's true that a gravitational wave does stretch and squeeze the wavelength of the light in the arms ever so slightly, it does NOT affect the fact that the beams will travel different distances as the wave changes each arm's length. And the only thing that matters to LIGO is how far the beams travel in each arm before being merged once again.
I didnt know that LIGO covered that in their FAQs. Anyhow, i think that LIGO reckon that the laser suffers a little bit of LC, not enough to hurt the wavelength. Because solids resist LC, ie LC due to GWs. Resist to me means that the laser suffers a little bit of LC. I saw this "resist" used in a paper from about 1997 (karnt remember the author).Aardwolf wrote:Yes and this issue is the very first question on their FAQ page;crawler wrote:Yes a plastic ruler.
