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.

If you think the Black Sea is placid, how did the wrecks get there? You haven’t spent any time there. A storm on the Black Sea is quite a spectacle and probably very scary on board ship.

I think its about time to put captions when a photo is from the real place that is being mentioned and when it is an AI interpretation. Got me confused there with the ship wrecks.

Ancient mariners discovered the undersea current. It is used to move boats by dropping a bucket overside and letting the current tow them into the black sea.

Where did you get the information regarding the tunnels under the sea? It's bonkers, never heard of such things - please cite some sources.

I live on a black see and 20 years ago fishermen saw an inexplicable sea monster. But for some reason no one talks about this since then... Underwater world is so interesting since the beginning of time, you know...

You didnt mention that the oldest gold on the planet "Trakia treasure" was found on the shores of Bulgaria, also the Black sea is not that calm every year people are drown into the sea because of its underneeths rivers

Wow, the Black Sea really is a treasure trove of history and mystery! The discovery of the world's oldest intact shipwreck, an ancient Greek trading vessel, is simply mind-blowing. It's incredible to think that such well-preserved pieces of history are still hidden beneath the sea's surface. Imagine what other secrets are waiting to be uncovered in those anoxic depths

The Mediterranean is the largest inland sea.

I am a Romanian, and we know about this wacky legends

[theotherandrew]

What a mixture of facts and mythology.

Black sea is not serene at all, it gets deep quick on the shore for humans unlike the aegean sea and the waves pull the sand beneath your feet, it has strong currents. One moment you are swimming one moment you’ll drown. I’ve literally seen a person dying because of a whirpool

[samirSch]

Huge flood 7, 5k years ago? Sounds biblical...like it or not.

[pl]

What is your source for the information about the tunnels beneath the black sea? I would like to know more please

[vladodobleja]

I am Romanian and I live near the Black Sea, in Bucharest!

[Fixundfertig]

How are there so many ship wrecks if the waters are so calm? 🤔

[Kevinmc-jl]

If there are any books at the bottom of the black sea they should be retrieved and restored books belonging in a library not at the bottom of sea.

In my opinion the most Mysterious Seas are The Baltic Sea, Black Sea, Caribbean Sea, Japan's Sea and of last, but not least of corse USA Miami's Sea Bermuda's Triangle that video about of the Black Sea where is a river under the Sea was really interesting WOW! 😮

[tarickabouldahab]

At 3.34 you show Fish
near wreck .is that possible?
The tunnels may not have been underwater dug, rather through the mountains. Then with rising sea levels submerged.

2010 ? Well we've been learning in school for decades about the Black Sea receiving salt water through underground rivers like back in 2006 back in Romania

We know more about the universe than we do about what is under water.
