Day of the Roots, 7th of Spring, 526 M.E. (Betelgeuse): I propose that somewhere in a remote section of North Carolina's Blue Ridge Mountains, there is a colony of ants. Some of the ants claim the existence of highly intelligent beings, "humans" they call them, from somewhere outside of their nest, maybe even from beyond the mountains, but they have no proof.
"If humans exist," the skeptical ants ask, "Why haven't they come visit our colony?" Surely, they reason, these intelligent humans would be curious about the customs and mores of the colony and would want to communicate with the ants. The believers counter that the humans would obviously want to do all that and more, but given the colony's territorial nature and the way they attacked the wasp that tried to visit, the humans are either afraid or intimidated to appear.
That's how I feel about both UFO conspiracy theorists and the Fermi paradox skeptics. The Fermi paradox is the contradiction between the high probability of the existence of extraterrestrial civilizations, based on the billions of stars and planets in the universe, and the lack of evidence or contact with any such civilizations.
I believe that given the countless, near-infinite number of stars and planets in the universe, there is lfe out there somewhere on some planet other than Earth. Statistically, if the right combination of amino acids started life here, it must also have happened sometime, somewhere else. The vast majority of planets are not suitable for organic life as we know it, but there are probably millions (billions?) of other planets where the spark could have started. On some subset of those planets, intelligent life may have evolved, and a subset of those planets may have developed life far more intelligent than us.
But here's the thing - if a species was so vastly more intelligent than us that they managed to figure a way to overcome the space/time challenges of traveling millions of light years, have mastered quantum physics to the point that they can harness relativity to their own purposes, what interest would they have in this ant colony Earth? We're no more capable of learning what they could have to offer than those ants in North Carolina are of translating Shakespeare form English to Chinese, or solving quadratic equations.
Look, I'm a compassionate person and I also have a tendency to anthropomorphize animals, but if I somehow realized that the North Carolina ants were about to engage in a vicious territorial war with an adjacent colony, a war that would end badly for both, my reaction still wouldn't be to attempt to communicate with the ants and intervene in the war. No, I'd think, "Oh, so that's what they do," and that would be that. So why do we think super-intelligent extraterrestrials would want to get involved with us and stop a potential nuclear war, even if it were disastrous to this planet?
I bring all this up because today The Guardian reported that Search for Extraterrestrial Intelligence (SETI) institute is suggesting that space "weather" may be making radio signals from aliens hard to detect. Stellar activity, such as solar storms and plasma turbulence from a star near “a transmitting planet,” can scramble such transmissions, potentially explaining the radio silence observed in SETI's searches.
“Plasma density fluctuations in stellar winds, as well as occasional eruptive events such as coronal mass ejections, can distort radio waves near their point of origin, effectively ‘smearing’ the signal’s frequency and reducing the peak strength that search pipelines rely on,” according to a SETI press release.
They are not incorrect about those challenges, although I do wonder why they're only realizing the problem now. But I disagree with any assumption that extraterrestrial intelligence has any intention on communicating with us. Especially that they're trying to but can't get through because of those pesky plasma fluctuations.
For all that we know (and we don't know very much), extraterrestrials have already observed us, have garnered all of the data and information they want or need, and have moved on. They may even still be here, occupying some extra-dimensional space right here in our midst.
How would we know?
