Is LIGO's detection of gravitational waves real, or is it detecting the ether?

I wrote a paper in 2015 called The Lies of LIGO. Think about what they are asking us to accept: two black holes 160 million light years away give off a gravity wave that is supposed to move a four-mile concrete tunnel just a smidgen, contracting its length by a millimeter or two, while a second tunnel at 90 degrees, the control, is not moved. And you have to detect it at two or three stations at the same time, or it is not the same wave. First, you do not even know if general relativity, which requires gravity waves, is right. Second, a gravity wave is supposedly a wave of spacetime, but when you ask what spacetime is, they admit it is not substantive, just a mathematical framework, so what exactly is waving and contracting your tunnel? Third, you do not even know the source is 160 million light years away, because the only proven way to measure stellar distance is parallax; redshift is not proven, and one paper listed 60 different possible causes of redshift. This is the same pattern as the Big Bang and the cosmic microwave background: it fit like a glove until the CMB turned out not to be smooth, and its unevenness formed the axis of evil, showing the earth at the center. LIGO, in my book, does not have enough to make it a credible theory, much less a scientific fact.
