This Sea Is the Most Mysterious in the World

The Black Sea is full of mysteries and interesting facts! Using remote-controlled vehicles, researchers found more than 40 ancient sunken ships in great condition underwater. There’s a theory called “The Black Sea Deluge Hypothesis,“ which suggests the Black Sea was once a big freshwater lake that flooded quickly, in just 1-3 years. Beneath the sea, there’s a vast network of tunnels that might connect Romania and Turkey, with chisel marks showing they were man-made, but no one knows who made them. Plus, the Black Sea has two layers of water: a habitable freshwater layer on top and a deep, salty layer below where only bacteria and microorganisms live. #brightside Animation is created by Bright Side. ---------------------------------------------------------------------------------------- Music from TheSoul Sound: Check our Bright Side podcast on Spotify and leave a positive review!
