Can't believe they don't show a photo of what appears to be a 10 meter in diameter, 2.7km deep hole.

There's a bright future in big holes. Imagine what we can get our hands on if we could find a nice, cheap way to dig 10+ km down all over the place. The mantle is 2000+km thick. Our deepest mines are 3-4 km deep. We could also harvest a ton of heat this way - and maybe even use it for garbage disposal. Master Of Orion 2 had the Deep Core Mines and Core Waste Dumps - maybe that's the way to go!

Is the idea of using a big hole for garbage disposal that we would dump the garbage into the molten core and let it burn? Or is it more about using the hole as a really deep landfill?

Interesting: "Towards the base, the ice is more than 120,000 years old and dates back to the last interglacial period, a time when the atmospheric temperature above Greenland was 5°C warmer than today."

I'm not a scientist so I'm curious why this is interesting.

Presumably because we can find well preserved organisms from that time.

Please, if the title is going to be that, at least remove the capitalization from that "m", so it represents an unity instead of "millions of something undisclosed".

Also, a space is needed.

Earlier quoted context omitted.

That’s what I was thinking, yes. You have to think HOW you pronounce the word. The ‘u’ in “unity” is pronounced as “you” which starts with a consonant. Hence, you use ‘a’ not “an”.

But Y is a vowel?

English rules for using "a" or "an" depend on sounds used in the next word, not particular letters. "A unit" and "An hour" are easy examples that might trip people up when focused on the letters used in spelling, but if you sound it out, you can probably work out what sounds best.

Thank you for pointing this out. I thought it was referring to the age of the samples taken before reading your comment. It made the abstract less disappointing.

I only clicked on the article because I thought it was the age of the samples too.

If something has a negative age, does that mean it is from the future?

The camera wouldn't take the picture, and then several of the scientists had to be sedated as they started acting strangely.

As long as they don't come up with schematics to build a white Marker...

For all we know that could be psyops by Lovecraft. Maybe it's not a white marker, it's a blue beacon.

Ice cores are a few inches across. The photo at the top of the article is not of the drill hole but of the hole they had to dig in the snow to get to the ice they actually drilled. See the photo of the final ice core [1] to see how miniscule the actual drill hole is. [1] https://science.ku.dk/english/press/news/2023/pay-dirt-for-i...

Why is is black and white though? also - how do they transfer energy to drill down 2.7km? or how the hell does it work?

See other comment, and "that's a fun thing to check youtube for", respectively =)
