A theory gaining traction on social media posits that the apocryphal Book of Enoch, an ancient text excluded from many biblical canons, describes a hidden prison for fallen angels located beneath Antarctica.

The Book of Enoch, traditionally attributed to Noah's great-grandfather, recounts tales of fallen angels, giants, and the origins of demons. While it survived for centuries in Ethiopia, its descriptions of imprisoned heavenly beings and references to the 'ends of the earth,' 'chambers of cold,' and burning mountains have recently been interpreted by some online users as a literal depiction of Antarctica.

Supporters of this theory point to descriptions in the text that they claim align with East Antarctica's subglacial lakes and the buried Gamburtsev Subglacial Mountains. An international research team between 2007 and 2009 utilized airborne radar to map these subterranean peaks.

The Book of Enoch expands on the Nephilim, giants mentioned briefly in the Old Testament. According to the text, 200 angels called the Watchers descended, fathered the Nephilim with human women, and taught forbidden knowledge. The text describes God commanding archangels to bind the Watchers and imprison them in a fiery abyss until the final judgment.

Proponents of the Antarctica theory highlight passages like 1 Enoch 18:12–16, where Enoch is shown seven imprisoned stars at the 'end of heaven and earth,' described as heavenly beings who 'transgressed the commandment of the Lord' and are bound until judgment. They interpret 'the end of heaven and earth' as Earth's southernmost point.

The theory further suggests that Enoch's description of seven mountains surrounding the prison matches the buried Gamburtsev Subglacial Mountains. A 2014 study noted that these ancient mountains show minimal weathering. Additional passages about sealed 'chambers of cold' and storehouses of snow and frost are seen as corresponding to Antarctica's ice sheet and subglacial lakes.

Although the manuscript survived for centuries in Ethiopia before becoming known to Western scholars in the late 18th century, one of its most unsettling visions has recently resurfaced on social media, where users argue it points to a hidden prison beneath the Antarctic ice

Another passage describing a location with 'no heaven above,' 'no firmly founded earth beneath,' and 'no water' is interpreted as a sealed chamber beneath the Antarctic ice. The theory also links unexplained radio signals detected by NASA's ANITA experiment in 2006 and 2014, which appeared to emerge from beneath the Antarctic ice, to Enoch's descriptions of 'voices' from an abyss.

However, the Book of Enoch does not explicitly mention Antarctica or radio waves. Mainstream biblical scholars generally interpret these passages as symbolic descriptions of a supernatural realm rather than a literal geographical location. Explanations for the ANITA experiment's anomalous signals proposed by scientists include unusual cosmic-ray interactions or other unknown physical processes, with no definitive consensus reached.
