THE RETURNING SKY
The verse 11 of Sura Tarik in the Qur'an, refers to the "returning" function
of the sky.
{{ÓBy Heaven with its cyclical systems.}}
(The Qur'an, 86:11)
This word interpreted as "cyclical" in Qur'an translations also has
meanings of "sending back" or "returning".
As known, the atmosphere surrounding the Earth consists of many layers.
Each layer serves an important purpose for the benefit of life. Research has
revealed that these layers have the function of turning the materials or rays
they are exposed to back into space or back down to the Earth. Now let us
examine with a few examples of this "recycling" function of the layers
encircling the Earth.
The troposphere, 13 to 15 kilometers above the Earth, enables water vapor
rising from the surface of the Earth to be condensed and turn back as rain.
The ozone layer, at an altitude of 25 kilometers, reflects harmful radiation
and ultraviolet light coming from space and turns both back into space.
The ionosphere, reflects radio waves broadcast from the Earth back down
to different parts of the world, just like a passive communications satellite, and
thus makes wireless communication, radio, and television broadcasting
possible over long distances.
The magnetosphere layer turns the harmful radioactive particles emitted
by the Sun and other stars back into space before they reach the Earth.
The fact that this property of the atmosphere's layers, that was onlt
demonstrated in the recent past was announced centuries ago in the Qur'an,
once again demonstrates that the Qur'an is the word of God.The presence of water
is essential for life on
Earth.
One of the
factors acting in the
formation of water is
the Troposphere, one
of the layers of the
atmosphere. The
troposphere layer
enables water vapour
rising from the surface
of the Earth to be
condensed and turn
back down to the
Earth as rain.
The atmosphere layer
that blocks the rays
that might be fatal to
life on Earth is the
Ozonosphere. The
Ozonosphere turns
harmful cosmic rays
like ultraviolet back to
space, hence
preventing them from
reaching the Earth and
harming life.
Each layer of the
atmosphere has
beneficial attributes
for human beings. The
Ionosphere layer, one
of the upper layers of
the atmosphere, for
example, reflects radio
waves broadcast from
a certain centre back
down to the Earth,
thus enabling
broadcasts to be
received from long
distances.
