In the two widest-ranging exercises on mapping the galaxies
carried out to date, scientists have made findings that offer serious
support for the Big Bang theory. The results of the research were presented
at the winter conference of the American Astronomical Society.
The wide extent of the distribution of galaxies is evaluated by astrophysicists
as one of the most important legacies from the first phases of the universe
to have come down to the present day. It is therefore possible to refer
to the information on the distribution and location of the galaxies as
"a window opening onto the history of the universe."
In their research that lasted several years, two independent teams, composed
of British, Australian and American scientists, produced a three-dimensional
map of some 266,000 galaxies. The scientists compared the data they collected
on the distribution of the galaxies with the data for the Cosmic Background
Radiation emitted everywhere in the universe, and made important discoveries
regarding the origin of galaxies. Researchers analysing the data concluded
that the galaxies formed where matter that formed 350,000 years after
the Big Bang relatively clustered together, and then assumed their shape
under the influence of the force of gravity.
According to the Big Bang theory, everything
began from the explosion of a point of infinite density and zero
volume. As time passed, space expanded and the gaps between heavenly
bodies grew.

The findings in question confirmed the Big Bang theory, which states
that the universe began from the explosion of a single point of zero volume
and infinite density some 14 billion years ago. This theory has constantly
been confirmed by tests consisting of decades of astronomical observations,
and stands unrivalled on the most solid of foundations. The Big Bang is
accepted by the great majority of present-day astrophysicists, and constitutes
scientific verification of the fact that God created the universe from
nothing.
In its ten-year-long research, the Anglo-Australian Observatory in the
Australian state of New South Wales determined the positions in space
of 221,000 galaxies by means of a three-dimensional mapping technique.
The survey, which was performed with a 3.9 metre diameter telescope at
the observation post, was almost ten times larger than any previous such
study. (1) Under the leadership of Dr. Matthew Colless,
director of the observatory, the team of scientists first determined the
position of galaxies relative to one another and the distances between
them. Then they modelled the distribution of the galaxies and studied
the minute variations in that model in great detail. The scientists offered
their research for publication in the journal Monthly Notices of the
Royal Astronomical Society.
In a similar study carried out by the Apache Point Observatory in New
Mexico, USA, the positions of some 46,000 galaxies in another region of
space were similarly mapped and their distribution was investigated. The
study, involving the use of a 2.5 metre diameter Sloan telescope, was
carried out under the leadership of Daniel Eisenstein of the University
of Arizona, and is to be published in the Astrophysical Journal. (2)
The results obtained by the two groups were announced during the winter
meeting of the American Astronomical Society in San Diego, California,
USA on 11 January, 2005.
Data obtained from the COBE satellite in 1992
revealed minute fluctuations in the emission of Cosmic Background
Radiation.

An Important Confirmation
The data obtained as the result of long and careful work confirmed estimates
made decades ago in the field of astronomy regarding the origin of the
galaxies. In the 1960s, theoreticians estimated that galaxies may have
seeded in regions where matter massed in a slightly higher concentration
shortly after the Big Bang. If that estimate is correct, then the seeds
of the galaxies should be capable of being observed in the form of tiny
fluctuations in heat levels in the remains of radiation left over from
the Big Bang and known as Cosmic Background Radiation.
Cosmic Background Radiation is heat radiation that only began being emitted
350,000 years after the Big Bang. This radiation, emitted everywhere in
the universe, represents a snapshot of the 350,000-year-old universe,
and can be observed rather like a fossil in the present day. This radiation,
first discovered in 1965, was recognised as definitive proof of the Big
Bang with various studies and observations, and was investigated in great
detail. Data obtained from the COBE (Cosmic Background Explorer) satellite
in 1992 confirmed the estimates made in the 1960s and revealed that there
were ripples in the Cosmic Background Radiation. (3)
Although at that time a partial link had been determined between these
and the formation of the galaxies, that link could not be definitely shown
until now.
However, that important link was constructed in the latest studies. Colless
and Eisenstein's teams determined a match between the ripples seen in
Cosmic Background Radiation and those in the distances between galaxies.
It was thus established that the galaxies seeded in places where matter
that emerged 350,000 years after the Big Bang concentrated in slightly
higher densities.
At a press conference on the subject, Dr. Eisenstein said that the way
galaxies are scattered across the sky now corresponds to the sound waves
that gave rise to that distribution. Researchers think that gravity affected
the waves and shaped the galaxies. Eisenstein made the following comment:
"We regard this as smoking-gun evidence that gravity has played
the major role in growing from the initial seeds in the microwave background
(left over from the Big Bang) into the galaxies and clusters of galaxies
that we see around us." (4)
In a statement to the AAP news agency, Russell Cannon, from the other
research team, noted that the findings were of the greatest importance,
and summarised the significance of the research in these terms:
"What we've done is show the pattern of the galaxies, the distribution
of the galaxies which we see here and now, is completely consistent
with this other pattern that's seen in remnants of the big bang
"
(5)
Findings were also obtained from the study regarding the levels of matter
and energy that constitute the universe, and the universe's geometrical
form. According to these, the universe consists of 4% normal matter, 25%
dark matter (matter that cannot be observed but that is calculated to
exist), and the rest of dark energy (mysterious energy that leads to the
universe expanding faster than expected). As for the geometrical shape
of the universe - it is flat.
Support for the Big Bang

The findings made in these studies have further strengthened the Big
Bang theory. Dr. Cannon said that the research added serious weight to
the Big Bang theory about the origin of the universe and emphasized that
support in these words:
"We've known for a long time that the best theory for the universe
is the Big Bang -- that it started in some enormous explosion in a tiny
space and it expanded ever since." (6)
In a comment regarding the studies, Sir Martin Rees, the well-known Cambridge
University astronomer, noted that despite using different statistical
techniques and observations, the teams had arrived at the same conclusion,
and that he regarded this as an indication of the results' accuracy. (7)
Physicsweb.org, one of the most important physical sciences portals on
the Internet, commented that the studies "provide further evidence
for the standard big bang plus inflation model of cosmology." (8)
Scientists learned that the universe had a beginning (Big Bang) and was
expanding (Inflation) by reading the radiation and heavenly bodies in
space thanks to the possibilities of modern science. However, these fundamental
data are not at all new to mankind. Mankind has been reading these two
facts, which scientists were only able to read in the depths of space
in the 20th century, in the Qur'an for the last 1,400 years.
Two Basic Pieces of Information about the Standard
Cosmological Model Are Provided in the Qur'an
In the Qur'an, and in the Torah and the Bible that were corrupted after
their revelation, God has revealed that the universe and all matter were
created out of nothing; in the Qur'an, the only text that has not been
corrupted, He reveals one other miraculous secret that the universe is
expanding.
The way the universe came into "being" from "non-being"
is reported thus in the Qur'an:
He is the Originator of the heavens and the earth. (Qur'an,
6:101)
The expansion of the universe, one of the main areas of research of modern
science, is revealed in this verse:
And it is We Who have constructed the heaven with might,
and it is We Who are steadily expanding it. (Qur'an, 51:47)
As we have seen, two elements of the standard cosmological model, the
Big Bang and Inflation, were reported in the Qur'an at a time when the
means of astronomical observation were very limited. This represents clear
proof that the Qur'an was revealed by God. The findings of modern science
are in complete agreement with what is related in the Qur'an, and these
latest studies once again draw attention to that close compatibility.
