Can we please stop calling humid rocks "ocean"? There is a word for that: aquifer.

Aquifer doesn't convey any sense of scale, and that's the important part in the article. "Scientists discover aquifer" wouldn't be interesting.

"Scientists discover aquifer the size of the Pacific ocean"

And I would like to say that "interesting" should be lower on the list of priority than "accurate" when it comes to headlines.

I wonder if this be related to the biblical flood story: on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened. Genesis 7:11

The most interesting theory I read recently is that biblical flood referes to an event that happened 5600 BC, when melting ice from the last little ice age caused water from Medditerrain Sea to flood through Bosfor, significantly increasing the size of Black Sea: https://en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis

There is however a lot of controversy around this theory.

The real thing is even more different than an ocean.

In an aquifer you have something like wet sand or wet rocks, i.e. there is sand/rocks and the water is in the space between them.

In this case, the molecules of water are inside the crystal structure. It's almost like a chemical reaction instead of only some inert object getting wet.

An usual similar compound is Cooper Sulfate that is nice because it changes color. The anhydrous version is white and you can get it heating the normal version. The normal version is blue and it has 5 water molecules per each CuSO4. But it is not wet like wet sand/rocks, the water is trapped inside he crystals. I can't find a good link but there is more info in https://en.wikipedia.org/wiki/Copper(II)_sulfate#Other_form_... there are some nice photos in https://www.google.com/search?tbm=isch&q=copper+sulfate+colo...

Headlines are marketing. They get people to buy the magazine or view the online adverts.

If you want strict accuracy without the sales element you need to go to a journal.

Why does the book get all the points for the things it gets right without getting points detracted for what it gets wrong?

We need to understand. We search for patterns. Not knowing is an ache that forces some to look and convinces others to stop looking.

Certainly, the search for meaning is the most fundamental human attribute after survival.

However, we tend to be fine for the search for bullshit.

Discussed (not particularly well) at the time: https://news.ycombinator.com/item?id=7885641

One interesting comment in that thread by 31reasons:

Is it possible that similar deposits of this rock ringwoodite are present in under the surface or in cores of other planets?

IANAG. Probably yes because the elements in these rocks are quite common, but I guess the difficult part is guessing how much water these rocks are trapping in each planet.

But I found in Google one interesting link: "Mars' Ocean May Have Descended Into the Mantle of the Planet" https://www.popularmechanics.com/space/moon-mars/a14470646/m...

Many translations do not talk about "windows" but about "floodgates". The authors of the bible were from a culture whose cosmology interpreted the blue sky as an ocean and believed it could be poured on the earth.

Cite?

(Apparently we are of a culture that believes water molecules trapped in certain minerals constitutes an ‘ocean.’)

Another instance of the scientific community converging to a consensus congruent with the Genesis account of creation. Genesis 2:5-6 "the Lord God had not sent rain on the earth ... but streams came up from the earth and watered the whole surface of the ground." Two other notable instances: the universe had a beginning (a Big Bang) and evolution occurred generally in the order described in Genesis 1 (nothing, plants,…

What do you think it gets wrong?
