The Biggest Unsolved Mysteries In The World

Voynich Manuscript

Named after the Polish-American antiquarian bookseller Wilfrid M. Voynich, who acquired it in 1912, the Voynich Manuscript is a detailed 240-page book written in a language or script that is completely unknown. Its pages are also filled with colorful drawings of strange diagrams, odd events and plants that do not seem to match any known species, adding to the intrigue of the document and the difficulty of deciphering it. The original author of the manuscript remains unknown, but carbon dating has revealed that its pages were made sometime between 1404 and 1438. It has been called "the world's most mysterious manuscript."

Theories abound about the origin and nature of the manuscript. Some believe it was meant to be a pharmacopoeia, to address topics in medieval or early modern medicine. Many of the pictures of herbs and plants hint that it many have been some kind of textbook for an alchemist. The fact that many diagrams appear to be of astronomical origin, combined with the unidentifiable biological drawings, has even led some fanciful theorists to propose that the book may have an alien origin.

One thing most theorists agree on is that the book is unlikely to be a hoax, given the amount of time, money and detail that would have been required to make it.

Kryptos

Kryptos is a mysterious encrypted sculpture designed by artist Jim Sanborn which sits right outside the headquarters of the CIA in Langley, Va. It's so mysterious, in fact, that not even the CIA has completely cracked the code.

The sculpture contains four inscriptions, and although three of them have been cracked, the fourth remains elusive (Read what the first three inscriptions say here). In 2006 Sanborn let slip that there are clues in the first inscriptions to the last one, and in 2010 he released another clue: the Letters 64-69 NYPVTT in part 4 encode the text BERLIN.
