Earth’s core is wilder than you can imagine
Mashable: James Van Orman, professor of geochemistry and mineral physics at the College of Arts and Sciences, said the innermost part of our planet, Earth’s core, has a profound impact on our lives—even if we can’t get a glimpse of this impossibly remote, hostile place. The core is about the size of Pluto, yet scientists found that distant world in our solar system nearly a century ago, before discovering proof of the core. “That gives an idea of how remote it is, even though it’s right under our feet,” Van Orman said.
