The Search for Alien Tech

Lately I’ve been binging on live solo performances from early in the careers of songwriter&#x2F;musicians who went on to bigger, flashier things. (Elton John, Old Grey Whistle Test, 1971; Greg Lake, Cal Jam, 1974; etc.) A recurring comment has been the expression of gratitude to have been alive in the same “blip” of time as the creator&#x2F;performer and to have seen them perform during their prime.<p>There’s a sense that in the history of the creation of music, the living presence of the creator&#x2F;performer wasn’t <i>huge</i> until recently, surely due to acceleration of distribution and access via broadcast media, and remained so for a decade or two (bobby sox, fainting at the sight of Elvis, Beatlemania, etc.). Then, as music has become more mediated through electronics (click, autotune, synth, DAW, etc., etc.) arguably the importance of the presence of the creator&#x2F;performer themselves has increasingly been buffered, muffled or otherwise reduced.<p>This helps me understand SETI and the Fermi Paradox. We’re not just looking for music, we’re looking for the pure signal of Elton between Reg and Captain Fantastic, maybe a 3 year window out of his 60 as a performer, and out of billions of years on the cosmic timeline. Before that he wasn’t on the radar; after it he became part of the background noise.

Solar panels and CFCs in exoplanets? They are too confined to our current development stage here on Earth. Not that civilizations don&#x27;t use them, ours does. But they are toys for the blink of an eye in cosmological time. The search makes more sense when it is for structures that, by their very function, are designed to last longer and span multiple stellar systems. Communication networks, and more precisely communication hubs next to dark objects moving in trajectories of low curvature--wandering planets and the like. If there are people in advanced alien civilizations, they don&#x27;t travel in spaceships.

Good chance for me to mention the excellent book ‘Cosmos and Culture’, again.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25566085" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25566085</a>

“For starters, looking for alien tech on Earth is probably a waste of time. ‘It’s a geologically active place, and, on top of that, life destroys everything quickly here,’ says Wright.” That’s a pretty harsh reaction for someone interested in evidence of alien life. We have good evidence of UAPs (UFOs) that are non-human technology flying around our own atmosphere. I do hope the search for technosignatures finds evidence, but I think that Avi Loeb’s Galileo Project will end up finding incontrovertible evidence soon.
