PROTECTED ROOF

PROTECTED ROOF

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




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.


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 270o C.

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. (http://www.jps.net/bygrace/index. html Taken from Big Bang Refined by Fire by Dr. Hugh Ross, 1998. Reasons To Believe, Pasadena, CA.)

The 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 2,500o 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.



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 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 from space





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 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.
