Miracle of the Qur'an: the seas that do not mix

Sura 55 "The Merciful":

19. He mixed the two seas that meet each other.

20. There is a barrier between them that they cannot cross.

Sura 25 "Discrimination":

53. He is the One Who mixed two seas (types of water): one is pleasant, fresh, and the other is salty, bitter. He placed a barrier and an insurmountable obstacle between them.

While exploring the expanses of water in the Strait of Gibraltar, Jacques Cousteau discovered an amazing fact, not explained by science: the existence of two water columns that do not mix with each other. They seem to be separated by a film and have a clear boundary between them. Each of them has its own temperature, its own salt composition, animal and flora. These are the waters of the Mediterranean Sea and the Atlantic Ocean touching each other in the Strait of Gibraltar.

“In 1962,” says Jacques Cousteau, “German scientists discovered that in the Bab el-Mandeb Strait, where the waters of the Gulf of Aden and the Red Sea converge, the waters of the Red Sea and the Indian Ocean do not mix. Following the example of our colleagues, we began to find out whether the waters of the Atlantic Ocean and the Mediterranean Sea mix. First we examined the water of the Mediterranean Sea - its natural level of salinity, density and the life forms inherent in it. We did the same thing in the Atlantic Ocean. These two masses of water have been meeting in the Strait of Gibraltar for thousands of years and it would be logical to assume that these two huge water masses should have mixed long ago - their salinity and density should have become the same, or at least similar. But even in the places where they converge closest, each of them retains its properties. In other words, at the confluence of two masses of water, the water curtain did not allow them to mix.”

Upon discovering this obvious and incredible fact the scientist was extremely surprised. “For a long time I rested on the laurels of this amazing phenomenon, inexplicable by the laws of physics and chemistry,” writes Cousteau.

But the scientist experienced even greater surprise and admiration when he learned that this was written about in the Koran 1,400 years ago. He learned about this from Dr. Maurice Bucaille, a Frenchman who converted to Islam.

“When I told him about my discovery, he skeptically told me that this was said in the Koran 1400 years ago. It was like a bolt from the blue for me. And indeed, this is how it turned out when I looked at the translations of the Koran. Then I exclaimed: “I swear that this Koran, from which modern science is 1400 years behind, cannot be human speech. This is the true speech of the Almighty.” After that, I accepted Islam and every day I was amazed at the truth, justice, ease, and usefulness of this religion. I am eternally grateful that He opened my eyes to the Truth,” Cousteau further writes.

All seas and oceans and rivers on Earth communicate with each other. The water surface level is the same everywhere.

But you rarely see such a border. This is the border between the seas.

And the most amazing mergers are truly those where there is a visible contrast, a clear boundary between seas or flowing rivers.

There are many on Earth mysterious places and phenomena. One of such phenomena can be called the meeting of reservoirs whose waters do not mix. Many believe that these are the laws of physics, others consider them an inexplicable anomaly, and still others attribute this phenomenon to the vagaries of nature.

Jacques Cousteau and the Strait of Gibraltar

In 1967, German scientists tried to find out the reasons why the waters of the Indian Ocean and the Red Sea do not mix in the Bab el-Mandeb Strait. Jacques Cousteau decided to follow the example of his colleagues and study the non-mixing of the water column of the Atlantic Ocean and the Mediterranean Sea in the Strait of Gibraltar by analyzing the density and salinity of the waters.

The scientist believed that over many millennia the waters of the two reservoirs should have mixed. But even in those places where the sea and ocean seem to touch each other, they still retain their distinctive features.

What is surface tension of water

As it turned out, the reason for the non-mixing of waters of different reservoirs lies in the tension of the surface, and this is the main parameter of water. Without going deep into physics: this is the force due to which water molecules can connect with each other, which is how a drop, puddle, stream, etc. appear. And the stronger the surface tension, the less volatility of the liquid.

Well, for example, alcohol has a very weak molecular binding force, so when it comes into contact with air it quickly evaporates. Fortunately, water has a very large value for this parameter, so there is still life on our planet.

You can visualize what surface tension is. To do this, take a bowl and slowly pour tea into it to the very brim. For some time, the tea will not overflow over the edges, and if you look closely, you can see a thin film on the surface of the drink, which will try to prevent the tea from spilling. This is what happens with reservoirs; each has its own surface tension, which, like a wall, prevents one reservoir from flowing into another.

Where can you see the boundaries between bodies of water?

In the northernmost part of Denmark, namely in the city of Skagen, the waters of the Baltic and North Seas meet. The Danes call the borders of the coast in Skagen “the end of the world”:

  • Atlantic Ocean and Caribbean Sea, Antilles

  • Rio Negro and Solimões rivers, Brazil

  • Uruguay River and its tributary, Argentina

  • Green and Colorado Rivers, Utah, USA

  • Alaknanda and Bhagirathi rivers, India

  • Jialing and Yangtze Rivers, China

  • Chuya and Katun rivers, Russia

  • Rivers Moselle and Rhine, Germany

  • Three rivers: Inn, Danube and Ilz, Germany

  • Rivers Rhone and Arve, Switzerland

By the way, adherents of the Muslim faith are convinced that bodies of water do not mix because Allah commanded so, because this was written in the Koran even before the time when natural phenomenon became known to science. They say that Jacques Cousteau converted to Islam only because he read about the non-mixing of waters in the Koran, and then was able to see all this in reality.

A not-so-rare phenomenon is a visible boundary between connected bodies of water: two seas, a sea and an ocean, a river and a tributary, etc. And yet, it always looks so unusual that you can’t help but wonder: why don’t their waters mix?
