#whatliesbeneath

Our friends at The Edges of Everythingness over on Facebook have sent us this. Imagine our Earth cut in half, a cross-section revealing what lies beneath 🌍. Is there a solid center, glowing with molten layers, or could it be hollow, stretching through to the other side? The mysteries beneath our feet are bigger than we think. #layers #earthcore #mystery #geology #whatliesbeneath
