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.

Mentioning the recent Chernobyl accident is weird too. Surely an accident from long ago that is expected to be detectable is far more helpful. All they proved is that nothing had entered since the Chernobyl accident.

Have there been many nuclear reactor meltdowns prior to Chernobyl?

Before 1986 there have been twelve "public" core meltdowns, and at least six, likely more, incidents not public on nuclear subs, etc.

You should look up how many live armed nuclear bombs have been accidentally dropped on mainland US soil.

More significantly, there's been a lot of above ground and atmospheric tests that have draped residuals across the planet, and a bunch of dirty Russian / former USSR sites that drift trace across Europe.

It's an AI article.

Looking for Chernobyl signature in cave during the late 1980s / early 1990s does seem daft - far more likely for them to be looking for residual "trace" from the atmospheric tests that doused the planet in "unnatural" residuals and odd isotopes.

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.

That has a lot more to do with whether the cave started out containing anything "more complex than insects." 5 million years isn't, like, an evolve-monkeys-from-scratch number of years. It's arguably an evolve-humans-from-chimps number of years. But if your cave doesn't contain any chimps... or even if it does but they all starve to death in Year 2 out of 5,000,000...

Humans didn’t evolve from chimps.

You could just look for isotopes from the atmospheric nuclear tests that were conducted? Doesn't need to be a reactor I would assume?

No but they could over 5 million years

> Yeah it has significant groundwater inflow (like 5L/s). where did it say this? i did a double-take because the article says the opposite, and i checked the wikipedia and didnt see it there either. is there another source of info? or am i being blind?

> Mesothermal, sulfidic groundwater (up to 1 mM in H2S) originating from an artesian sulfidic aquifer underlying the region enters at the bottom of the cave’s lower passages. This results in a constant flow occurring tens of centimeters to 1 m below the water surface at flow rates of about 5 L/s https://pmc.ncbi.nlm.nih.gov/articles/PMC10672346/

Right, so it was sealed only in the biological sense, which makes sense since there needs to be an inflow of energy

Isn't there a nuclear bomb sitting somewhere in a swamp in the USA that everybody lost?
