Why SETI Might Have Been Missing Alien Signals - Lemmy.World

“Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches.” Science paper: https://iopscience.iop.org/article/10.3847/1538-4357/ae3d33 [https://iopscience.iop.org/article/10.3847/1538-4357/ae3d33] Review article: https://www.theregister.com/2026/03/10/seti_admits_its_search_for/ [https://www.theregister.com/2026/03/10/seti_admits_its_search_for/]

FFS…

SETI PRESUMES that the way we’re going to detect extraterrestrial civilizations, is their beaming TONS of photons at us, in crisp signal.

WHY TF would they do that??

Why wouldn’t they ditch the energy-wasteful TV-style broadcast, for energy-efficient fiber-optics?

There’s, in my view, only a SINGLE century of civilization-evolution in-which tons of broadcast energy is poured helter-skelter all throughout the sky.

Before that it isn’t done because the tech doesn’t exist, & after that, it isn’t done because it’s idiotic to be doing it.

So, instead of presuming “all civilizations are broadcasting, why aren’t we seeing them??”, we OUGHT be presuming “we’re trying to see a single-century of civilized-evolution, & maybe this is the wrong method for finding other-world’s life”.

Maybe there’s some alien civilization who’s actively pointing a radio signal in our direction so they can communicate with us. I don’t know… maybe the aliens are observing how friendly we are to each other and really want to connect?

Like what we do with things like arecibo.

Yeah! Like, hmmmm… was it really a storm that brought Arecibo down? Or … was the storm just used as a cover by ET hackers?
