Earth never stops surprising us. Every corner of the planet offers some sort of natural peculiarity with an explanation that makes us wish we'd studied harder in junior high Earth science class.
Some of these sites are challenging to get to; others are busy tourist destinations. They keep natural scientists searching for answers and the rest of us astounded by the secrets and mysteries the world continues to reveal.
Sometimes it is hard to believe that unsolved mysteries still exist in this day and age. In the last century, humankind has made extraordinary technical advancements. We have walked on the Moon, uncovered the building blocks of life itself, DNA, ventured deeper into the oceans than ever before and invented the self-strirring coffee mug! However even with our amazing progress as a species there are still mysteries out there to which the solution eludes us. Here you will find some of the most puzzling unsolved mysteries in recorded history.
This app will be regularly updated everymonth with new mysteries.
