Workers Drilling in Romania Broke Into a Cave Sealed for 5.5 Million Years — and Found an Entire Living World That Has Never Seen the Sun
Workers Drilling in Romania Broke into a Cave Sealed for 5.5M Years
In 1986, workers drilling near the Black Sea coast broke into Movile Cave, sealed for 5.5 million years. Inside, researchers found a thriving ecosystem of dozens of endemic species, all blind and unpigmented, surviving in toxic air and permanent darkness. The food chain is powered by chemosynthesis, not sunlight, making it a unique subterranean ecosystem and a model for potential life on other planets.
It is a reminder that the planet is not finished revealing itself, that discoveries of real consequence can still turn up under a dusty patch of farmland, and that life is substantially more inventive about where and how it survives than we tend to assume.

The wikipedia article says "While animals have lived in the cave for 5.5 million years, not all of them arrived simultaneously. One of the most recent animals recorded is the cave's only species of snail, Heleobia dobrogica, which has inhabited the cave for slightly more than 2 million years."

Speleology aside, just a few days ago in one of HN discussions I was told LLM-produced content is already indistinguishable from human-made. But I'm sure I would have pretty good chances to correctly guess even the exact brand which helped to write this sloppy text. And it's the same with many stories I read.

Just because the cave is sealed now, does not mean it has been sealed for millions of years. Even for geology, 5.5M years is a long time. I don't understand how they can claim it never had connections to the outside, just because it doesn't have connections now.

Does anyone have the original source of this information? This article seems to be AI generated:

Interesting that being sealed for 5 million years did not yield any life forms more complex than insects.
Maybe sun and space are importance factors for intelligence.
