Miracle of the Quran: seas that don't mix
Sura 55 "The Merciful":
19. He mixed two seas that meet each other.
20. Between them there is a barrier 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 set up a barrier and an insurmountable obstacle between them.
While exploring the expanses of water in the Strait of Gibraltar, Jacques Yves Cousteau discovered an amazing fact that is not explained by science: the existence of two water layers that do not mix with each other. They seem to be separated by a film and have a clear border between them. Each of them has its own temperature, its own salt composition, animal and vegetable world... This is water 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 if the waters of the Atlantic Ocean and the Mediterranean Sea are mixing. First, we examined the water of the Mediterranean Sea - its natural salinity, density and inherent life forms. We did the same 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 masses of water 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 my laurels of this amazing phenomenon, which cannot be explained by the laws of physics and chemistry,” writes Cousteau.
But the scientist experienced even greater surprise and admiration when he learned that it was written about this in the Koran 1400 years ago. He learned about this from Dr. Maurice Boucaya, 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 to me. Indeed, it turned out that way when I looked at the translations of the Koran. Then I exclaimed: “I swear that this Quran, from which modern science is 1,400 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, usefulness of this religion. I am infinitely grateful that He opened his eyes to the Truth, ”- writes further Cousteau.
It is said that the Atlantic and Pacific Oceans do not mix their waters. It is rather difficult for us to understand how identical fluids cannot combine. In this article "I and the World" will try to figure it out.
Of course, to say that the waters of the oceans do not mix at all is wrong. So why is the border between them so clearly visible? In the place where they touch, different directions of currents, as well as the difference in the level of density of water and the amount of salt in it. On the line of their intersection, it is even clearly visible that the colors of the reservoirs are completely different. The photo clearly shows this joint.
The famous scientist Jacques Cousteau once spoke about the directions of currents, when the force of the earth at an angle to the axis of rotation prevents the waters from completely mixing at the place of their meeting. But what is interesting is that this phenomenon was written in the Quran 1400 years ago.
The invisible merging of the oceans occurs only in the Southern Hemisphere, since in the Northern they are separated by continents.
Such clear boundaries can be seen not only in the place where the oceans meet, but also the seas, and between river basins. For example, the North and Baltic Seas do not mix due to the different density of their waters.
At the confluence of the Irtysh and Ulba, in the first river the water is clear, in the second it is muddy.
In China: the clear Jialing River flows into the brown-muddy Yangtze.
The two rivers, having traveled almost 4 km, never mix. This is due to the different speed of their currents and temperatures. The Rio Negro is slower and warmer, while the Solimoins flows faster, but it is cooler.
And there are many such examples. From the outside, all this seems like mysticism until an exact explanation comes.

Photo - The Strait of Gibraltar, connecting the Mediterranean Sea and the Atlantic Ocean. The waters 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, fauna and flora.
Earlier, in 1967, German scientists discovered the fact of non-mixing of water layers in the Bab el-Mandeb Strait, where the waters of the Gulf of Aden and the Red Sea, the waters of the Red Sea and the Indian Ocean converge. Following the example of his colleagues, Jacques Cousteau began to find out if the waters of the Atlantic Ocean and the Mediterranean Sea were mixing. First, he and his team investigated the water of the Mediterranean Sea - its natural salinity, density and inherent life forms. The same was done 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 masses of water 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, a water curtain did not allow them to mix.
If you look closely, in the second photo you can see a different color of the sea, and in the first one - different wavelengths. And between them, as if, an impenetrable wall.
The point here is surface tension:
Surface tension is one of the most important parameters water. It determines the strength of adhesion between the molecules of a liquid, as well as the shape of its surface at the interface with air. It is due to surface tension that a drop, puddle, jet, etc. are formed. The volatility (evaporation) of any liquid also depends on the adhesion forces of the molecules. The lower the surface tension, the more volatile the liquid. Alcohols and other organic solvents have the lowest surface tension.
If water had a low surface tension, it would evaporate very quickly. But water, nevertheless, has a rather high surface tension.
Visually, surface tension can be represented as follows: if you slowly pour tea into a cup to the brim, then for some time it will not pour out through the rim. In transmitted light, you can see that a thin film has formed over the surface of the liquid, which prevents the tea from pouring out. It swells as you add it, and only, as they say, with the “last drop”, the liquid is poured over the edge of the cup.
Likewise, the waters of the Atlantic Ocean and the Mediterranean Sea are unable to mix. The amount of surface tension is determined by different degrees of density sea \u200b\u200bwater, this factor is like a wall that prevents the mixing of waters.
Not such a rare phenomenon is the visible border between communicating bodies of water: two seas, a sea and an ocean, a river and a tributary, etc. And yet, it always looks so unusual that one inevitably wonders: why their waters don't mix?

All seas and oceans and rivers on Earth communicate with each other. The level of the water surface is the same everywhere.
But such a border is rare. This is the border between the seas.
And the most amazing mergers are truly those where contrast is visible, a clear border between seas or flowing rivers.
