Even the new LIGO paper is 100 percent empirically detached from any sort of visual confirmation of their claim.
The common denominator in astronomy theory today is that in order for anything to actually "work" correctly mathematically, it somehow must be 'invisible'.
It's amusing to be old enough to actually remember a "big bang" theory that didn't involve inflation, or necessarily include any "exotic' forms of matter, or energy. The new additions to the big bang concept during my lifetime have only added to the complete detachment of the big bang concept from empirical physics. It seems to have opened up the door for "anything goes as long as it's invisible" in the realm of astronomy. The sad part is that LCDM is currently only 5 percent distinguishable from astrology, and even that measly 5 percent is mostly based upon pure pseudoscience.
It really sucks to live in the literal "dark" ages of astronomy. There's simply nothing good about it. LCDM theory impedes real scientific progress by eating all the public lunch dollars being spent on astronomy, and it's just irrational, superstitious nonsense.
