A NASA satellite recently detected a 'gravity anomaly' below the Antarctic ice igniting renewed claims of a 'Nazis in Anarctica' conspiracy theory that has been floating around for decades. As per the theory, the Nazis have or had a secret underground base on the Antarctic continent.
A gravity anomaly is a difference between the theoretical calculated value of gravity in a locale. Which should reflect variations in the density of the underlying rocks. It is often helpful in high tech prospecting, determing the nature of the rock and mineral deposits in a particular location and pinpointing mineral deposits.
A joint mission of NASA and the German Aerospace Centre was conducted from 2002 up till October 2017. The project known as 'Grace' or Gravity Recovery and Climate Experiment used twin satellites to map out detailed measurements of Earth's gravitional field. Measuring gravity anomalies, GRACE showed how mass is distributed around the Earth and how it varies over time at specific geographic locales.
Antarctica produced a quagmirical hiccup when in 2006, researchers led by Ralph von Frese and Laramie Potts used data from GRACE to discover a 300-mile-wide anomaly below the Anarctic ice. The team initially postulated that the anomaly was a massive impact crater caused by an asteroid millions of years ago. [ Massive ‘anomaly’ lurks beneath ice in Antarctica ]
Conspiracy theorists however have disputed the teams 'impact crater' theory citing insufficient evidence. Some believe that something bizarre is buried deep below the frozen Anarctic ground.
Durring the Second World War Nazi bases were allegedly built in the Antarctic and some evidence of possible entrances have been discovered around the continent.
Not long after the Nazi defeat in WWII a US military operation of 4,700 men was dispatched under the alleged 'guise' of researching Anarctica. It was known as Operation Highjump, was organized by Rear Admiral Richard E. Byrd, Jr. and ran from August 1946 till February 1947.
Admiral Byrd was famous during his lifetime for his explorations of our planets polar etremities. Conspiracy theories associated with Byrd's exploits claimed that he discovered entrances to a vast Hollow Earth which harbored lost civilizations. The Hollow Earth: The Greatest Geographical Discovery in History Made by Admiral Richard E. Byrd in the Mysterious Land Beyond the Poles published in 1964 makes claims to Byrd's 'secret diary' which he allegedly penned in February of 1947, around the same time Operation Highjump concluded.
We are crossing over the small mountain range and still proceeding northward as best as can be ascertained. Beyond the mountain range is what appears to be a valley with a small river or stream running through the center portion. There should be no green valley below! Something is definitely wrong and abnormal here! We should be over Ice and Snow! To the portside are great forests growing on the mountain slopes. Our navigation Instruments are still spinning, the gyroscope is oscillating back and forth!
The following month, in March, 1947, a Chilean newspaper called El Mercurio published the following excerpt of an interview with Admiral Byrd which the good Admiral neither corroborated or refuted.
'Adm. Byrd declared today that it was imperative for the United States to initiate immediate defence measures against hostile regions. The admiral further stated that he didn’t want to frighten anyone unduly but that it was a bitter reality that in case of a new war the continental United States would be attacked by flying objects which could fly from pole to pole at incredible speeds. Admiral Byrd repeated the above points of view, resulting from his personal knowledge gathered both at the north and south poles, before a news conference held for International News Service.'
KGB, the soviet equivalent of the CIA released documents from the early 90s revealing that were multiple other less publicized and secretive missions by the US military to Anarctica as well. Conspiracy theorists claim the true purpose of the missions was to investigate possible entrances in the frozen landscape leading to an 'inner Earth'.
In 2018, GPS tracking software from a company called Strava appeared to show a number of buildings below the ice. A YouTube channel 'SecureTeam10' – uploaded footage using the Strava software, appearing to show heat signatures from an isolated location in the Antarctic. Heat Anomaly Below Antarctica Melting Ice
