Scientists examined several phenomena succes seabed. In addition dark because there was no light, had they found a similar movement of waves. These waves occur at a meeting between layers sea water of different density or mass density. The water in the bottom of the ocean has a higher density than the water above it.
This phenomenon can not be seen with the eye, but can be identified by studying the temperature and salinity changes in certain places. This wave has properties such as surface waves.
And fifteen centuries ago, the Qur'an was revealed this phenomenon in verse:
"Or like darkness in the deep ocean, overwhelmed by the waves, the waves above it (also), on top of it (again) clouds; a superimposed dark-joins, if he took out his hand, Nor he could see it, (and) those who were given no light (guidance) by God Nor he has a bit of light. " (Surat An-Nur ^: 40)
