Bloop


The Bloop is the name given to an ultra-low frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The source of the sound remains unknown.
The sound, traced to somewhere around 50° S 100° W (a remote point in the south Pacific Ocean west of the southern tip of South America), was detected several times by the Equatorial Pacific Ocean autonomous hydrophone array,[1] which uses U.S. Navy equipment originally designed to detect Soviet submarines.

According to the NOAA description, it "rises rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km." The NOAA's Dr. Christopher Fox does not believe its origin is man-made, such as a submarine or bomb, or familiar geological events such as volcanoes or earthquakes. While the audio profile of the Bloop does resemble that of a living creature, the source is a mystery both because it is different from known sounds and because it was several times louder than the loudest living animal, the blue whale.[2] Five other significant unexplained sounds have been named by NOAA: Julia, Train, Slow Down, Whistle, and Upsweep.[3][4][5]
Dr. Christopher Fox of the NOAA speculated that the Bloop may be ice calving in Antarctica.[6] A year later journalist David Wolman paraphrased Dr. Fox who suggested it was likely animal in origin

Voynich manuscript


The Voynich manuscript is a handwritten book thought to have been written in the early[1] 15th century and comprising about 240 vellum pages,[notes 1] most with illustrations. Although many possible authors have been proposed, the author, script, and language remain unknown. It has been described as "the world's most mysterious manuscript".[2]
Generally presumed to be some kind of ciphertext, the Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II. Yet it has defied all decipherment attempts, becoming a historical cryptology cause célèbre. The mystery surrounding it has excited the popular imagination, making the manuscript a subject of both fanciful theories and novels.
In 2009, University of Arizona researchers performed C14 dating on the manuscript's vellum, which they assert (with 95% confidence) was made between 1404 and 1438.[3][4] In addition, the McCrone Research Institute in Chicago found that much of the ink was added not long afterwards, confirming that the manuscript is an authentic medieval document.[3]
The book is named after the Polish-Lithuanian-American book dealer Wilfrid M. Voynich, who acquired it in 1912. The Voynich manuscript is owned by the Beinecke Rare Book and Manuscript Library of Yale University, and is formally referred to as "Beinecke MS 408". The first facsimile edition was published in 2005.[5]
