The Quran on Deep Seas and Internal Waves
God has said in the Quran:
Or (the unbelievers state) is like the darkness in a deep sea. It
is covered by waves, above which are waves, above which are clouds.
Darknesses, one above another. If a man stretches out his hand, he
cannot see it.... (Quran 24:40)
This verse mentions the darkness found in deep seas and oceans, where
if a man stretches out his hand, he cannot see it. 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 (see figure 1). Below a
of 1000 meters there is no light at all. Human beings are not
to dive more than forty meters without the aid of submarines or
special equipment. Human beings cannot survive unaided in the deep
dark part of the oceans, such as at a depth of 200 meters.
