UNIVERSE IS EXPANDING
"INFINITESIMAL" TO "INFINITE"
The universe came
into existence about 12 to 15 billion years ago from an infinitesimal point
of action, is a commonly accepted scientific theory. Since that period
of time, astronomical number of galaxies have spread further and further,
away from the point of that action. The numbers of these galaxies have
gone so high, that no one can imagine that figure even in approximate terms.
It is even more difficult to imagine the total area covered by these expanding
galaxies. They are still speeding away at their own receding speeds,
alike the wood splinters flying away from the woodcutter's block. Briefly,
the unobservable universe has now expanded beyond any one's imagination
and it continues to spread further.
Below are a couple of excerpts from Compton's Interactive Encyclopedia
Deluxe, 1998 edition that give us the scientific evidences for this expanding
universe:
According
to the Doppler effect, a general relationship seems to exist throughout
the universe: the greater the speed of a galaxy, the greater its distance.
This relationship suggests that the system of galaxies is expanding. Suppose
the galaxies were at one time in a rather small volume of space. After
a time, the fast galaxies would have sped far from the original position,
while the slow galaxies would still be nearby. The result would be a velocity-distance
relationship exactly like the one observed.
Since the universe
appears to be expanding, it seems that it must have been smaller in the
past. This is the basis for evolutionary theories of the universe. If one
could trace the galaxies back in time, one would find a time at which they
were all close together. Observations of the expansion rate indicate that
this was between 10 and 20 billion years ago. Thus we have a picture of
an evolving universe that started in some kind of explosion -- the big
bang.
Here is another extract from the same encyclopedia:
Just
as the pitch, or frequency, of a train whistle lowers as the train moves
away from a listener, the frequency of light from a receding galaxy should
appear lower to an observer than if the galaxy and observer were motionless
relative to each other. This kind of change is called a "red shift" because
visible light is shifted downward in frequency toward the long-wavelength,
red end of the electromagnetic spectrum. The theory of an expanding universe
was confirmed in 1929 by the astronomer Edwin Hubble of the United States,
who showed from an analysis of the red shifts of distant galaxies that
they are indeed receding from our galaxy and with velocity of recession
that is proportional to distance. Hence, the universe is expanding.
We now comprehend that the universe is expanding.
The next question is by how much? To get a better glimpse of the distance
covered by the expanding universe since the Big Bang, here is a simple
calculation. The approximate diameter of our Milky Way galaxy is said to
be 100,000 light-years. One light-year is equal to 9,460,500,000,000 kilometers.
That makes our galaxy to be 9.460 trillion kilometers
in diameter and 29.7186 trillion kilometers in circumference. The
universe which has been observed so far, with the scientific gadgets, has
billions of galaxies like the Milky Way. The total circumference of it
in kilo-meters, so to say, can blow an average person's head. Furthermore,
the modern science has yet to develop the instruments that can observe
the planets, stars and galaxies that do exist in the heavens, beyond the
realm of the observed universe. One has but to admit that from an "Infinitesimal"
point of action the universe has indeed expanded to the "Infinite".
THEOLOGICAL NOTES
On one clear
night, nearly 4000 years ago, the Almighty God asked a nomad named Abraham
to come outside of his tent and look at the heavens. He asked the traveling
tradesman to count the stars, if he was capable of doing that. Obviously,
that was and is no easy task even today. However, God wanted to convey
him a futuristic Message. He said to prophet Abraham; "that
many shall be your descendants" (Genesis 15:5).
Who could have known at that
time what the Almighty had really promised to this old and aged nomad.
Four millenniums later, we know that there are nearly 3 billion Jews, Christians
and Muslims together, who proudly claim that prophet Abraham is their patriarch
and they are the "Children of Abraham". No one today knows what that number
could be in Y3K or later. God has indeed mystical allegorical ways of communicating
the futuristic events.
A theologian once proposed an interesting analogy
to explain how vast was the unobservable universe. He said; Let us imagine
that every star (planets included) of our universe was like a tiny grain
of sand that you find on the beach. If you were to collect all the stars
that your naked eye could see on a clear night, they would probably fill
your grandmother's thimble. If you were to collect all the stars that your
country's biggest electronic telescope could observe, they would probably
fill an industrial wheel barrow. If you were to collect all the stars of
the unobservable universe that your space scientists could theoretically
count on their computers, they would probably fill-up a railway freight
train. A train so long that if it was to pass a point of observation, at
the speed of one car a second, it would take three years to pass. The last
comparison may not be perfect but it is indisputable since the universe
has not yet stopped expanding.
Nearly, two and half millenniums
after God asked prophet Abraham to look at the heavens and count the stars,
He revealed to prophet Muhammad that He was the One that has been spreading
these stars. Just as the people around Abraham could not understand what
was that futuristic Divine Message, the people around Muhammad could not
fully understood as we do today, what God really meant when he revealed
the following verse:
And the
Heaven - with our hands have we built it up, and given it its expanse;
Translation by Reverend J. M. Rodwell
And heaven - We
built it with might, and We extend it wide.
Translation by Arthur J. Arberry
With the power
and skill did We construct the Firmament: for it is We Who create the vastness
of Space,
Translation by Abdulla Yusuf Ali
Transliteration:
wa- as- samaa' banaynaa -haa bi-
aydi(n) wa- 'in(na)
-naa la- mosicon
(Qur'an 51: 47)
Comment:
The
word "firmament" does not refer to the so called "Theory of Firmament".
It is a noun. According to the Webster's Dictionary it means; the whole
vault of the sky with its myriad stars etc.
The word "expanse" used by the translator J. M. Rodwell comes from the
Latin word, "expansum" and it means; "to spread out".
No doubt
our universe is expanding but that expansion is not eternal as once thought.
The scientists of our era are now telling us that after reaching its peak
of the expansion, this Universe will slowly retreat and contract. Surprisingly,
the Qur'an tells us that this universe has been pulsating (expanding and
contracting). He is the one who has determined the periods of pulsation.
