The Protected Roof
The atmosphere only lets rays required for life reach the
Earth. Ultraviolet rays, for example, make it to the world
only partially. This is the most appropriate range to allow
plants to make photosynthesis and eventually for all living
things to survive.
In the Qur'an, God calls
our attention to a very interesting attribute of the sky:
"We made the sky a preserved and protected
roof yet still they turn away from Our Signs.."
(The Qur'an, 21:32)
This attribute of the sky has been proved by scientific
research carried out in the 20th century.
The atmosphere surrounding the earth serves crucial functions
for the continuity of life. While destroying many meteors big and
small as they approach the earth, it prevents them from falling
to earth and harming living things.
In addition, the atmosphere filters the light rays coming
from space that are harmful to living things. Interestingly, the
atmosphere lets only harmless and useful rays- visible light, near
ultraviolet light, and radio waves pass through. All of this radiation
is vital for life. Near ultraviolet rays, which are only partially
let in by the atmosphere, are very important for the photosynthesis
of plants and for the survival of all living beings. The majority
of the intense ultraviolet rays emitted from the sun are filtered
out by the ozone layer of the atmosphere and only a limited-and
essential-part of the ultraviolet spectrum reaches the Earth.
The protective function of the atmosphere does not end
here. The atmosphere also protects the earth from the freezing cold
of the space, which is about minus 270° C.
This illustration shows meteors that
are about to crash into the earth. The celestial bodies wandering
in space could pose a serious threat to the Earth. Yet, God,
He Who creates most perfectly, has made the atmosphere a protective
roof. Thanks to this special protection, most meteoroids do
not harm the Earth, as they fall to pieces in the atmosphere.
Most people looking at the sky do not
think about the protective aspect of the atmosphere. They
almost never think what kind of a place the world would be
like if this structure did not exist. The above photo belongs
to a giant crater caused by a meteor that fell in Arizona,
in the USA. If the atmosphere did not exist, millions of meteoroids
would fall to the Earth and the Earth would become an inhabitable
place. Yet, the protective aspect of the atmosphere allows
living things to survive in safety. This is certainly God's
protection of people, and a miracle proclaimed in the Qur'an.
|The energy released
in a Sun burst is so powerful that the human mind would hardly
comprehend it: A single burst is equivalent to 100 billion atomic
bombs similar to the one dropped on Hiroshima. The world is
protected from the destructive effects of this energy by the
atmosphere and the Van Allen Belts.
||As we move from the
Earth, which is perfectly fitted for human life, beyond the
atmosphere into the space, we come across a freezing cold. The
world is protected from the freezing cold of space, which is
around -270 degrees, by the help of the atmosphere.
The magnetosphere layer, formed by the
magnetic field of the Earth, serves as a shield protecting
the earth from celestial bodies, harmful cosmic rays and particles.
In the above picture, this magnetosphere layer, which is also
named Van Allen Belts, is seen. These belts at thousands of
kilometres above the earth protect the living things on the
Earth from the fatal energy that would otherwise reach it
All these scientific findings
prove that the world is protected in a very particular way.
The important thing is that this protection was made known
in the Qur'an in the verse "We made the sky a preserved
and protected roof" 1,400 years ago.
It is not only the atmosphere that protects the Earth
from harmful effects. In addition to the atmosphere, the Van Allen
Belt, a layer caused by the magnetic field of the Earth, also serves
as a shield against the harmful radiation that threatens our planet.
This radiation, which is constantly emitted by the Sun and other
stars, is deadly to living things. If the Van Allen belt did not
exist, the massive outbursts of energy called solar flares that
frequently occur in the Sun would destroy all life on Earth.
Dr. Hugh Ross has this to say on the importance of Van
Allen Belts to our lives:
In fact, the Earth has the highest
density of any of the planets in our Solar System. This large nickel-iron
core is responsible for our large magnetic field. This magnetic
field produces the Van-Allen radiation shield, which protects the
Earth from radiation bombardment. If this shield were not present,
life would not be possible on the Earth. The only other rocky planet
to have any magnetic field is Mercury - but its field strength is
100 times less than the Earth's. Even Venus, our sister planet,
has no magnetic field. The Van-Allen radiation shield is a design
unique to the Earth.(1)
energy transmitted in just one of these bursts detected in recent
years was calculated to be equivalent to 100 billion atomic bombs
similar to the one dropped on Hiroshima. Fifty-eight hours after
the burst, it was observed that the magnetic needles of compasses
displayed unusual movement and 250 kilometers above the earth's
atmosphere, the temperature suddenly increased to 2,500° C.
In short, a perfect system is at work high above the
Earth. It surrounds our world and protects it against external threats.
Scientists only learned about it recently, yet centuries ago, God
informed us in the Qur'an of the world's atmosphere functioning
as a protective shield.
