Have aliens already visited Earth? Who built Stonehenge and why? Could Bigfoot really exist? And what really happened aboard the Mary Celeste? Written and authenticated by a panel of specialist writers and consultants, A History of the Unexplained explores these questions and many more, providing a comprehensive and impartial account of the world’s most enduring mysteries – from Peru’s Nazca lines and the Bermuda Triangle to out-of-body experiences and UFO encounters – with details of the history of each one and leading theories that have been proposed over time.Fascinating and thought-provoking in equal measure, the book examines strange natural phenomena from ball lightning to creature storms, explores the potential existence of mysterious "cryptids" (animals not recognized by "mainstream science"), such at the Orang Pendek and Chupacabra, and examines a wide range of other intriguing subjects at the very margins of scientific enquiry, including telekinesis and the "Hollow Moon" theory.Packed with incredible images and perfect for anyone with an enquiring mind, this essential book is the ultimate guide to the biggest mysteries of all time. It will challenge what you think you know about science and history – forever.
