> What if it's such advanced protocol layering and encryption that those alien signals appear to us to be "cosmic noise"? Another interesting way to speculate is the "under our nose" concept, which is the concept that the existing distribution of stars and galaxies, as well as the recorded background noise, might be the byproduct of alien intervention. Binary star systems are a popular speculative example of "starivore" civilizations that consume entire stars that have been moved into the alien civilization's own star system, and perhaps some combination of multiple stars in a single system are not "naturally" occurring in the absence of alien influence. To an unsuspecting observer, some forms of distant astronomical-scale engineering could be mistakenly interpreted as natural astrophysics that the observers then incorporate into their standard models when refactoring to account for all of the observed data... Usually the simple explanations are correct, but when your models require really insane updates to handle the observed data, perhaps there are other explanations? At the same time though, what recourse would we have if 99% of the visible universe was already astro-engineered? |

There is currently no evidence which suggests stars are being moved. We should see either large gravitational tugs or engines such as Shkadov thrusters. The latter should be plainly visible. The former should be easily detected by extrasolar planet detection methods. Unless the tugs are spherical, the light curves of the tugs would definitely pique interest. In any case, moving a star seems a rather extreme and expensive measure. It is probably more effective to consume the star onsite and use the energy locally or send only the energy back.
There seems to be no evidence of stars being consumed, either. Dyson spheres (or swarms) have actually been searched for locally by comparing visible and infrared wavelengths over sections of the sky. None have been found. Intergalactic searches have also been done by looking for galaxies which glow too brightly in the far infrared. No luck.
It is not just a question of a mistaken belief that the artificial is natural. The properties of light are the same here on Earth as they are billions of light years away. Further, for all those galaxies and stars to be engineered in the same way aross billions of light years (with some points being unable to communicate with others since the Big Bang), is all but impossible. Life would have to evolve at effectively the same rate and come up with the same solutions in all those hundreds of billions of galaxies (and yet somehow be different here in the Milky Way). Given the variety of life on Earth and the variety of solutions it has evolved, that seems unlikely.
