Something smells fishy
The Fish Who Could Not Imagine Air
One fish, one big idea, and commenters instantly turned it into a flying-fish roast
TLDR: The article uses a fish that can’t imagine air to argue humans may also be blind to parts of reality we’re not built to understand. The community’s big reaction was a hilarious instant roast: one commenter boiled the whole cosmic idea down to, essentially, “what about flying fish?”
A dreamy philosophy-meets-science essay about a fish who cannot imagine air somehow got the internet’s favorite treatment: immediate heckling. The piece argues that humans may be just like that fish, trapped inside our own normal and unable to picture what lies beyond it. In plain English, it’s saying the universe might have whole ways of existing that we can’t even guess at, because our brains and bodies were built for this world only. Heavy stuff! But the comment section? It grabbed the grand cosmic metaphor by the tail and shouted, basically, “Nice theory, but you forgot flying fish.”
That one-liner from zabzonk became the entire mood. The strongest reaction wasn’t some deep debate about reality — it was a cheeky dunk on the article’s setup. The joke lands because the essay is so serious, so sweeping, so determined to explore the limits of imagination, and then along comes one commenter with a tiny pin to pop the balloon. Obviously not a flying fish became the thread’s standout meme, turning a meditation on hidden worlds into a comedy bit about the one fish that absolutely would have notes.
And that’s the drama here: lofty idea versus internet nitpick. Some readers will see a clever correction, others a classic comment-section drive-by. Either way, the community turned an abstract thought experiment into a punchline, and honestly? That contrast is half the fun.
Key Points
- •The article uses a fish physicist thought experiment to explore how a complete internal scientific model can still miss an external medium such as air.
- •It identifies five separate constraints behind the fish’s blindness: fixed assumptions about the medium, escape into a thinner regime, the need for bodily change, an unreportable interface, and different connectivity.
- •The article argues that human speculation often focuses too narrowly on inaccessible places rather than the full structure of epistemic limits.
- •It proposes that a hidden regime might involve rarefaction rather than added structure, appearing as almost nothing from within our current framework.
- •The article links this possibility to the idea that space and locality may emerge from entanglement structure, and contrasts it with wormhole-style models.
