THE EXPANSION OF THE UNIVERSE

In the Qur'an, which was revealed fourteen centuries ago at a time
when the science of astronomy was still primitive, the expansion
of the universe was described in the following terms:
And it is We Who have constructed the heaven
with might, and verily, it is We Who are steadily expanding it.
The word "heaven," as stated in the verse above,
is used in various places in the Qur'an. It is referring to space
and the wider universe. Here again, the word is used with this meaning,
stating that the universe "expands." The Arabic word "moosiaaoona"
in the term "inna lamoosiaaoona," translated into English
as "it is We Who are steadily expanding it", comes
from the verb "evsea," meaning "to expand." The prefix
"la" emphasises the following name or title and adds a sense of
"to a great extent." This expression therefore means "We expand
the sky or the universe to a great extent." This is the very conclusion
that science has reached today. 1
Until the dawn of the 20th century, the only view prevailing
in the world of science was that "the universe has a constant nature
and it has existed since infinite time." However, modern research,
observations, and calculations carried out by means of modern technology
have revealed that the universe in fact had a beginning and that
it constantly "expands."
At the beginning of the 20th century, the Russian physicist
Alexander Friedmann and the Belgian cosmologist Georges Lemaitre
theoretically calculated that the universe is in constant motion
and that it is expanding.
From the moment of the Big Bang, the universe has been constantly
expanding at a great speed. Scientists compare the expanding
universe to the surface of a balloon that is inflated.
This notion was confirmed by the use of observational data in 1929.
While observing the sky with a telescope, Edwin Hubble, the American
astronomer, discovered that the stars and galaxies were constantly
moving away from each other. This discovery is regarded as one of
the greatest in the history of astronomy. During these observations,
Hubble established that the stars emit a light that turns redder
according to their distance. That is because according to the known
laws of physics, light heading towards a point of observation turns
violet, and light moving away from that point assumes a more reddish
hue. During his observations, Hubble noted a tendency towards the
colour red in the light emitted by stars. In short, the stars were
moving further and further away, all the time. The stars and galaxies
were not only moving away from us, but also from each other. A universe
where everything constantly moves away from everything else implied
a constantly expanding universe. The observations carried out in
the following years verified that the universe is constantly expanding.
In order to gain a clearer understanding of this,
let us imagine the universe to be the surface of a balloon being
inflated. In the same way that the more the balloon is inflated,
the further away the points on its surface move from one another,
celestial bodies also move away from one another as the universe
expands. This was theoretically discovered by Albert Einstein, regarded
as one of the greatest scientists of the 20th century.
However, in order to avoid violating the "static universe model"
that was generally accepted at that time, Einstein laid that discovery
aside. He would later describe this as the greatest blunder of his
This fact was explained in the Qur'an in a time when telescopes
and similar technological advancements were not even close to being
invented. This is because the Qur'an is the Word of Allah: the Creator
and Ruler of the entire universe.
