Darkness in the Seas and Internal
"Or (the unbelievers' state) are like
the darkness of a fathomless sea which is covered by waves above
which are waves above which are clouds, layers of darkness,
one upon the other. If he puts out his hand, he can scarcely
see it. Those God gives no light to, they have no light."
(The Qur'an, 24:40)
The general environment in deep seas is described
in the book named Oceans:
The darkness in deep seas and
oceans is found around a depth of 200 meters and below. At this
depth, there is almost no light. Below a depth of 1000 meters
there is no light at all.(12)
Today, we know about the general structure of the
sea, the characteristics of the living things in it, its salinity,
as well as the amount of water it contains, its surface area
and depth. Submarines and special equipment, developed with
modern technology, enable scientists to obtain this information.
Human beings are not able to dive more than 40 meters
down without the aid of special equipment. They cannot survive
unaided in the deep, dark parts of the oceans, such as at a
depth of 200 meters. For these reasons, scientists have only
recently been able to discover these detailed pieces of information
about seas. However, the statement of "darkness in a deep
sea" was used in Sura Nur 1,400 years ago. It is certainly
one of the miracles of the Qur'an that such information was
given at a time where no equipment to enable man to dive into
the depths of the oceans was available.
made with today's technology have revealed that between
3 and 30 percent of the sunlight is reflected at the surface
of the sea. Then, almost all of the seven colours of the
light spectrum are absorbed, one after another, in the first
200 meters, except for blue light (picture at left). Below
a depth of 1,000 meters, there is no light at all. (above
picture). This scientific fact was pointed out in the verse
40 of Sura Nur in the Qur'an 1,400 years ago.
In addition, the statement in verse 40 of Sura Nur
"…like the darkness of a fathomless sea which is covered
by waves above which are waves above which are clouds…"
draws our attention to another miracle of the Qur'an.
||The picture to the left represents internal waves at interface
between two layers of water of different densities. The
lower layer is denser then the upper one. This scientific
fact, declared in verse 40 of Sura Nur of the Qur'an 14
centuries ago, has been discovered by today's scientists
only very recently.
Scientists have recently discovered
that there are internal waves, which "occur on density
interfaces between layers of different densities." These
internal waves cover the deep waters of seas and oceans because
deep water has a higher density than the water above it. Internal
waves act like surface waves. They can break, just like surface
waves. Internal waves cannot be seen by the human eye, but they
can be detected by studying temperature or salinity changes
at a given location.(13)
The statements in the Qur'an run absolutely parallel
to the above explanation. Without research, one can only see
the waves on the surface of the sea. It is impossible for one
to know about the internal waves beneath the sea. Yet, in Sura
Nur, God draws our attention to another type of wave that occurs
in the depths of the oceans. Certainly, this fact, which scientists
has discovered very recently, shows once again that the Qur'an
is the word of God.
