    So geology.

    I fucking hate that website with a passion.

    They post nothing but horseshit for dummies.

    edit: I informally petition the moderator(s) to ban that domain

      This “is kind of crazy,” said Harriet Lau, a geodynamicist at Brown University who was not involved with either study. If material is effusing from the core into the mantle, is the boundary between them “as distinct as we think?”

      Sounds like there’s some interesting new science happening.

      I quite like Quanta Magazine, they at least manage to write some pretty good articles on quantum mechanics which are both approachable by layman and accurate.

      No, the stuff that comes out of a volcano is magma (which is then called lava when it reaches the surface). It comes from the mantle which is just below the crust.

      The core is at the center of the earth and has a composition that is very different from magma. There’s an inner and outer core and I assume they’re talking about the outer core here since the inner core is thought to be solid.

        Yes, but it gets to the surface, and how does it get to the surface? Through volcanoes. Not all volcanoes are material from the outer core, but that is the only way it reaches the surface.

          I was trying to answer OP’s question “isn’t that what volcanoes are” by clarifying that volcanoes are formed by the release to the surface of magma from the mantle. If they are now discovering there is also some core material mixed in with the lava in some volcanoes, that’s interesting and we might mention that as a minor component in those cases. But to say regarding material from the core, “that’s what volcanoes are” would be inaccurate. That would be some weird metallic-ass volcano if it was made from outer core material.

      What’s newly discovered is material from the core coming out, as opposed to just magma.

    The research concludes that this abyssal wall has doorways.

    Anyone have “Kaiju” on their 2025/26 bingo card?
