{"product_id":"hollow-earth","title":"Hollow Earth","description":"\u003cdiv\u003eBeliefs in mysterious underworlds are as old as humanity. But the idea that the earth has a hollow interior was first proposed as a scientific theory in 1691 by Sir Edmond Halley (of comet fame), who suggested that there might be life down there as well. \u003ci\u003eHollow Earth\u003c\/i\u003e traces the surprising, marvelous, and just plain weird permutations his ideas have taken over the centuries. From science fiction to utopian societies and even religions, \u003ci\u003eHollow Earth\u003c\/i\u003e travels through centuries and cultures, exploring how each era's relationship to the idea of a hollow earth mirrored its hopes, fears, and values. Illustrated with everything from seventeenth-century maps to 1950s pulp art to movie posters and more, \u003ci\u003eHollow Earth\u003c\/i\u003e is for anyone interested in the history of strange ideas that just won't go away.\u003c\/div\u003e","brand":"Grand Central Publishing","offers":[{"title":"Default Title","offer_id":41514398417074,"sku":"9780306815331","price":21.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0536\/7418\/0786\/files\/unnamed_81259a9d-1f24-4128-ab39-b2551df6dc4c.jpg?v=1724427058","url":"https:\/\/shop.hachettebookgroup.com\/products\/hollow-earth","provider":"Hachette Book Group","version":"1.0","type":"link"}
