Scientists know where aliens might be, but humans will never see them

EXCERPT: . . . Tomonori Totani, an astrophysicist at the University of Tokyo, proposes that the Fermi paradox could be addressed by widening the scope of potential “abiogenesis” events, which is the term for the origins of life. Instead of focusing on the emergence of life within the observable universe, he probes the likelihood of abiogenesis in “the whole inflationary universe”—including everything beyond the cosmological horizon—according to a study published in February in Scientific Reports
[...] Indeed, the entire universe may well have no limits at all. From this perspective, it's no wonder we haven’t found signs of complex life in such a small sample size. Perhaps that means that the evolution of sentient beings on Earth is a singular event within the cosmological horizon. “Some people say that abiogenesis by random reactions is impossible because of too-low probability even within the observable universe,” Totani noted. “However, if life can emerge in the real size of an inflationary universe, there is no difficulty to explain the existence of life on Earth.”
Totani is not the first scientist to ponder the idea that life could be abundant in the unobservable universe. For instance, he cites a 2007 study by Eugene Koonin, senior investigator at the National Center for Biotechnology Information, that suggests that an infinite universe, which could contain a “multiverse” of many universes, would make the emergence of life “inevitable.”
“In contrast to the traditional cosmological models of a single, finite universe, this worldview provides for the origin of an infinite number of complex systems by chance, even as the probability of complexity emerging in any given region of the multiverse is extremely low,” Koonin said in the study. “This change in perspective has profound implications for the history of any phenomenon, and life on Earth cannot be an exception,” he concluded.
While this is a satisfying hypothesis for resolving the Fermi paradox, it is also excruciating to imagine that the universe could be teeming with intelligent aliens beyond the cosmological horizon, where we could never hope to contact them. (MORE - details)
Not sure I get it, even with another youtube video that shows it rotating. (Yeah, I do, but it seems a stretch even for pareidolia.)

INTRO: Coronavirus cosmology? Planetary personal protective equipment? Or just imaginative astronomers? A massive asteroid 1.3 miles wide that is on course to fly by Earth next week has drawn special attention from scientists, who noticed that in their radar images it has the appearance of wearing a face mask.
