Mu (lost Continent)

Mu (lost Continent)

Mu is the name of a hypothetical continent that allegedly existed in one of Earth's oceans, but disappeared at the dawn of human history.

The concept and the name were proposed by 19th century traveler and writer Augustus Le Plongeon, who claimed that several ancient civilizations, such as those of Egypt and Mesoamerica, were created by refugees from Mu—which he located in the Atlantic Ocean. This concept was popularized and expanded by James Churchward, who asserted that Mu was once located in the Pacific.

The existence of Mu was disputed already in Le Plongeon's time. Today, scientists universally dismiss the concept of Mu (and of other lost continents like Lemuria) as physically impossible, since a continent can neither sink nor be destroyed in the short period of time required by this premise. Mu is today considered to be a fictional place.
