Most people take it for granted that we have yet to make contact with an extraterrestrial civilization. Trouble is, the numbers don’t add up. Our Galaxy is so old that every corner of it should have been visited many, many times over by now. No theory to date has satisfactorily explained away this Great Silence, so it’s time to think outside the box. Here are eleven of the weirdest solutions to the Fermi Paradox.
There’s no shortage of solutions to the Fermi Paradox. The standard ones are fairly well known, and we’re not going to examine them here, but they include the Rare Earth Hypothesis (the suggestion that life is exceptionally rare), the notion that space travel is too difficult, or the distances too vast, the Great Filter Hypothesis (the idea that all sufficiently advanced civilizations destroy themselves before going intergalactic), or that we’re simply not interesting enough.
But for the purposes of this discussion, we’re going to look at some of the more bizarre and arcane solutions to the Fermi Paradox. Because sometimes it takes a weird explanation to answer a weird question. So, as Enrico Fermi famously asked, “Where is everybody?”
