From Plato all the way to today, many scholars in the field have contemplated the existence of this highly technologically advanced ancient civilization and the reason for its downfall. If you start talking about the lost ancient city of Atlantis, most people will probably think you’re living in ‘la la’ land. Many people are unaware that this city has been studied seriously for hundreds of years. For example, we can see that it was a subject of significant importance for researchers at the Smithsonian Institution, as emphasized by their Annual Report of the Board of Regents of The Smithsonian Institution...

Portuguese scientists have found a depression on the Atlantic Ocean floor they think may be an impact crater. The roughly circular, 6km-wide hollow has a broad central dome and has been dubbed the "Fried Egg" because of its distinctive shape. It was detected to the south of the Azores Islands during a survey to map the continental shelf. If the Fried Egg was made by a space impactor, the collision probably took place within the past 17 million years... It lies under 2km of water about 150km from the Azores archipelago. The depressed ring sits roughly 110m below the...

Explanation: What on Earth is that? The Richat Structure in the Sahara Desert of Mauritania is easily visible from space because it is nearly 50 kilometers across. Once thought to be an impact crater, the Richat Structure's flat middle and lack of shock-altered rock indicates otherwise. The possibility that the Richat Structure was formed by a volcanic eruption also seems improbable because of the lack of a dome of igneous or volcanic rock. Rather, the layered sedimentary rock of the Richat structure is now thought by many to have been caused by uplifted rock sculpted by erosion. The above image...
