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, discussed the theories about the core of the Earth, the innermost part of our planet. 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. |
