An Attempt At Making Sense of "The Idea of Creation".
The
hypothesis outlined below doesn’t claim to be the work of the author. In
confession, I am obliged to note that, the scientific data collated here to
substantiate some of my philosophical ideas is totally out of my league. So a
great gratitude goes to the scientists whose sole purpose in life is the
pursuit of TRUTH and a rational understanding of the universe we call HOME.

The Big
Bang Theory
As
Chris LaRocco and Blair Rothstein put it: “It sure was BIG!!!”
The
Hubble Telescope's deepest view of the universe teaches us about the
beginning. We certainly know that our universe exists, however, this
knowledge alone has not satisfied mankind's quest for further understanding.
Our curiosity has led us to question our place in this universe and
furthermore, the place of the universe itself. Throughout time we have asked
ourselves these questions: How did our universe begin? How old is our
universe? How did matter come to exist? Obviously, these are not simple
questions and throughout our brief history on this planet much time and
effort has been spent looking for some clue. Yet, after all this energy has
been expended, much of what we know is still only speculation.
We
have, however, come a long way from the mystical beginnings of the study of
cosmology and the origins of the universe. Through the understandings of
modern science we have been able to provide firm theories for some of the
answers we once called hypotheses. True to the nature of science, a majority
of these answers have only led to more intriguing and complex questions. It
seems to be inherent in our search for knowledge that questions will always
continue to exist.
Although
in this short chapter it will be impossible to tackle all of the questions
concerning the creation of everything we know as reality, an attempt will be
made to address certain fundamental questions of our being. It will be
important to keep in mind that all of this information is constantly being
questioned and reevaluated in order to understand the universe more clearly.
For our purposes, through an examination of what is known about the Big Bang
itself, the age of the universe, and the synthesis of the first atoms, we
believe that we can begin to answer several of these key questions.
THE BIG
BANG
One of
the most persistently asked questions has been: How was the universe created?
Many once believed that the universe had no beginning or end and was truly
infinite.
Through
the inception of the Big Bang theory, however, no longer could the universe
be considered infinite. The universe was forced to take on the properties of
a finite phenomenon, possessing a history and a beginning.
About
15 billion years ago a tremendous explosion started the expansion of the
universe. This explosion is known as the Big Bang. At the point of this event
all of the matter and energy of space was contained at one point.
What existed
prior to this event is completely unknown and is a matter of pure
speculation.
This occurrence
was not a conventional explosion but rather an event filling all of space
with all of the particles of the embryonic universe rushing away from each
other. The Big Bang actually consisted of an explosion of space within itself
unlike an explosion of a bomb were fragments are thrown outward. The galaxies
were not all clumped together, but rather the Big Bang lay the foundations
for the universe.
The
origin of the Big Bang theory can be credited to Edwin Hubble. Hubble made
the observation that the universe is continuously expanding. He discovered
that a galaxys velocity is proportional to its distance. Galaxies that are
twice as far from us move twice as fast. Another consequence is that the
universe is expanding in every direction. This observation means that it has
taken every galaxy the same amount of time to move from a common starting
position to its current position. Just as the Big Bang provided for the
foundation of the universe, Hubbles observations provided for the foundation
of the Big Bang theory.
Since
the Big Bang, the universe has been continuously expanding and, thus, there
has been more and more distance between clusters of galaxies. This phenomenon
of galaxies moving farther away from each other is known as the red shift. As
light from distant galaxies approach earth there is an increase of space
between earth and the galaxy, which leads to wavelengths being stretched.
In
addition to the understanding of the velocity of galaxies emanating from a
single point, there is further evidence for the Big Bang. In 1964, two
astronomers, Arno Penzias and Robert Wilson, in an attempt to detect
microwaves from outer space, inadvertently discovered a noise of
extraterrestrial origin. The noise did not seem to emanate from one location
but instead, it came from all directions at once. It became obvious that what
they heard was radiation from the farthest reaches of the universe which had
been left over from the Big Bang. This discovery of the radioactive aftermath
of the initial explosion lent much credence to the Big Bang theory.
DEEP
THOUGHTS
It is
extremely difficult to separate this subject of science from daily
existential pondering. Everyone at some point in time has grappled with the
question of why we are here? Some have found refuge in the sheer philosophic
nature of this question while others have taken a more scientific approach.
These particular wanderers have taken the question to a higher level,
concentrating not only on human existence but the existence of everything we
know as real.
If you
sit and try to imagine the whole of the entire universe it would be
mind-boggling. However, science has now told us that the universe is, in
fact, finite, with a beginning, a middle, and a future.
It is
easy to get caught up in the large scale of the issue in discussing years by
the billions, yet, this time still passes. As we travel through our own lives
here on Earth, we also travel through the life of our universe.

Chaos
Theory
THE
FIRST ATOMS
Now
that an attempt has been made to grapple with the theory of the Big Bang, the
next logical question to ask would be what happened afterward? In the
minuscule fractions of the first second after creation what was once a
complete vacuum began to evolve into what we now know as the universe. In the
very beginning there was nothing except for a plasma soup. What is known of
these brief moments in time, at the start of our study of cosmology, is
largely conjectural. However, science has devised some sketch of what
probably happened, based on what is known about the universe today.
Immediately
after the Big Bang, as one might imagine, the universe was tremendously hot
as a result of particles of both matter and antimatter rushing apart in all
directions. As it began to cool, at around 10^-43 seconds after creation,
there existed an almost equal yet asymmetrical amount of matter and
antimatter. As these two materials are created together, they collide and
destroy one another creating pure energy. Fortunately for us, there was an
asymmetry in favour of matter.
As a
direct result of an excess of about one part per billion, the universe was
able to mature in a way favourable for matter to persist. As the universe
first began to expand, this discrepancy grew larger. The particles which
began to dominate were those of matter. They were created and they decayed
without the accompaniment of an equal creation or decay of an antiparticle. As
the universe expanded further, and thus cooled, common particles began to
form.
These
particles are called baryons and include photons, neutrinos, electrons and
quarks would become the building blocks of matter and life as we know it.
During the baryon genesis period there were no recognizable heavy particles
such as protons or neutrons because of the still intense heat. At this moment,
there was only a quark soup. As the universe began to cool and expand even
more, we begin to understand more clearly what exactly happened.
After
the universe had cooled to about 3000 billion degrees Kelvin, a radical
transition began which has been likened to the phase transition of water
turning to ice.
Composite
particles such as protons and neutrons, called hadrons, became the common
state of matter after this transition. Still, no matter more complex could
form at these temperatures. Although lighter particles, called leptons, also
existed, they were prohibited from reacting with the hadrons to form more
complex states of matter.
These
leptons, which include electrons, neutrinos and photons, would soon be able
to join their hadron kin in a union that would define present-day common
matter.
Big Bang Was
Followed by Chaos, Mathematical Analysis Shows
(Sep.
7, 2010) — Seven years ago Northwestern University physicist Adilson E.
Motter conjectured that the expansion of the universe at the time of the big
bang was highly chaotic. Now he and a colleague have proven it using rigorous
mathematical arguments.
The
study, published by the journal Communications in Mathematical Physics,
reports not only that chaos is absolute but also the mathematical tools that
can be used to detect it. When applied to the most accepted model for the
evolution of the universe, these tools demonstrate that the early universe
was chaotic.
Certain
things are absolute. The speed of light, for example, is the same with respect
to any observer in the empty space. Others are relative. Think of the pitch
of a siren on an ambulance, which goes from high to low as it passes the
observer. A longstanding problem in physics has been to determine whether
chaos -- the phenomenon by which tiny events lead to very large changes in
the time evolution of a system, such as the universe -- is absolute or
relative in systems governed by general relativity, where the time itself is
relative.
A
concrete aspect of this conundrum concerns one's ability to determine
unambiguously whether the universe as a whole has ever behaved chaotically.
If
chaos is relative, as suggested by some previous studies, this question
simply cannot be answered because different observers, moving with respect to
each other, could reach opposite conclusions based on the ticks of their own
clocks.
"A
competing interpretation has been that chaos could be a property of the
observer rather than a property of the system being observed," said
Motter, an author of the paper and an assistant professor of physics and
astronomy at Northwestern's Weinberg College of Arts and Sciences. "Our
study shows that different physical observers will necessarily agree on the
chaotic nature of the system."
The
work has direct implications for cosmology and shows in particular that the
erratic changes between red- and blue-shift directions in the early universe
were in fact chaotic.
Motter
worked with colleague Katrin Gelfert, a mathematician from the Federal
University of Rio de Janeiro, Brazil, and a former visiting faculty member at
Northwestern, who says that the mathematical aspects of the problem are
inspiring and likely to lead to other mathematical developments. An important
open question in cosmology is to explain why distant parts of the visible
universe -- including those that are too distant to have ever interacted with
each other -- are so similar.

Sound
creates Light. Atoms constitute into form. From Dark Matter to Anti-matter
through to Matter. Mass over time could also mean the birth of ‘Time’. After
about one to three minutes had passed since the creation of the universe,
protons and neutrons began to react with each other to form deuterium, an
isotope of hydrogen. Deuterium, or heavy hydrogen, soon collected another
neutron to form tritium. Rapidly following this reaction was the addition of
another proton which produced a helium nucleus. Scientists believe that there
was one helium nucleus for every ten protons within the first three minutes
of the universe. After further cooling, these excess protons would be able to
capture an electron to create common hydrogen. Consequently, the universe
today is observed to contain one helium atom for every ten or eleven atoms of
hydrogen.
While
it is true that much of this information is speculative, as the universe ages
we are able to become increasingly confident in our knowledge of its history.
By studying the way in which the universe exists today it is possible to
learn a great deal about its past.

galaxies, then stars, then planets. Spatial distribution of celestial bodies
in a harmony that preludes order.
AN
AGING UNIVERSE
We now
have something of a handle on two of the most important quandaries concerning
the universe; however, one major question remains. If the universe is indeed
finite, how long has it been in existence? Again, science has been able to
expand upon what it knows about the universe today and extrapolate a theory
as to its age. By applying the common physical equation of distance over
velocity equaling time, which again uses Hubbles observations, a fairly
accurate approximation can be made.
The two
primary measurements needed are the distance of a galaxy moving away from us
and that galaxys red shift. An unsuccessful first attempt was made to find
these distances through trigonometry. Scientists were able to calculate the
diameter of the Earths orbit around the sun which was augmented through the calculation
of the Suns motion through our own galaxy.
Unfortunately,
this calculation could not be used alone to determine the enormous distance
between our galaxy and those which would enable us to estimate the age of the
universe because of the significant errors involved.
The
next step was an understanding of the pulsation of stars. It had been
observed that stars of the same luminosity blinked at the same rate, much
like a lighthouse could work where all lighthouses with 150,000 watt light
bulbs would rotate every thirty seconds and those with 250,000 watt light
bulbs would rotate every minute.
With
this knowledge, scientists assumed that stars in our galaxy that blinked at
the same rate as stars in distant galaxies must have the same intensity.
Using trigonometry, they were able to calculate the distance to the star in
our galaxy.
Therefore,
the distance of the distant star could be calculated by studying the
difference in their intensities much like determining the distance of two
cars in the night. Assuming the two cars headights had the same intensity, it
would be possible to infer that the car whose headlights appeared dimmer was
farther away from the observer than the other car whose headlights would seem
brighter. Again, this theory could not be used alone to calculate distance of
the most far-away galaxies. After a certain distance it becomes impossible to
distinguish individual stars from the galaxies in which they exist. Because
of the large red shifts in these galaxies a method had to be devised to find
distance using entire galaxy clusters rather than stars alone.
By
studying the sizes of galaxy cluster that are near to us, scientists can gain
an idea of what the sizes of other clusters might be. Consequently, a
prediction can be made about their distance from the Milky Way much in the
same way the distance of stars was learned. Though a calculation involving
the supposed distance of the far-off cluster and its red shift, a final
estimation can be made as to how long the galaxy has been moving away from
us. In turn, this number can be used inversely to turn back the clock to a
point when the two galaxies were in the same place at the same time, or, the
moment of the Big Bang. The equation generally used to show the age of the
universe is shown here:
(distance
of a particular galaxy) / (that galaxys velocity) = (time)
or
4.6 x
10^26 cm / 1 x 10^9 cm/sec = 4.6 x 10^17 sec
This
equation, equaling 4.6 x 10^17 seconds, comes out to be approximately fifteen
billion years. This calculation is almost exactly the same for every galaxy
that can be studied.
However,
because of the uncertainties of the measurements produced by these equations,
only a rough estimate of the true age of the universe can be fashioned. While
finding the age of the universe is a complicated process, the achievement of
this knowledge represents a critical step in our understanding.

Atmospheric
and environmental changes of formed galaxies, stars and even ‘planets’ occur.
Pre-eminence of hydrogen and other gases essential for ‘Life’. On select
planets around certain stars in certain galaxies.
Stars
Stars
are the most widely recognized astronomical objects, and represent the most
fundamental building blocks of galaxies. The age, distribution, and
composition of the stars in a galaxy trace the history, dynamics, and
evolution of that galaxy.
Moreover,
stars are responsible for the manufacture and distribution of heavy elements
such as carbon, nitrogen, and oxygen, and their characteristics are
intimately tied to the characteristics of the planetary systems that may
coalesce about them. Consequently, the study of the birth, life, and death of
stars is central to the field of astronomy.
Stars
are born within the clouds of dust and scattered throughout most galaxies. A
familiar example of such as a dust cloud is the Orion Nebula, revealed in
vivid detail in the adjacent image, which combines images at visible and
infrared wavelengths measured by NASA's Hubble Space Telescope and Spitzer
Space Telescope. Turbulence deep within these clouds gives rise to knots with
sufficient mass that the gas and dust can begin to collapse under its own
gravitational attraction.
As the
cloud collapses, the material at the center begins to heat up.
Known
as a protostar, it is this hot core at the heart of the collapsing cloud that
will one day become a star. Three-dimensional computer models of star
formation predict that the spinning clouds of collapsing gas and dust may
break up into two or three blobs; this would explain why the majority the
stars in the Milky Way are paired or in groups of multiple stars.
As the
cloud collapses, a dense, hot core forms and begins gathering dust and gas.
Not all of this material ends up as part of a star — the remaining dust can
become planets, asteroids, or comets or may remain as dust.
In some
cases, the cloud may not collapse at a steady pace. In January 2004, an
amateur astronomer, James McNeil, discovered a small nebula that appeared
unexpectedly near the nebula Messier 78, in the constellation of Orion.
When
observers around the world pointed their instruments at McNeil's Nebula, they
found something interesting — its brightness appears to vary. Observations
with NASA's Chandra X-ray Observatory provided a likely explanation: the
interaction between the young star's magnetic field and the surrounding gas
causes episodic increases in brightness.
A star
the size of our Sun requires about 50 million years to mature from the
beginning of the collapse to adulthood. Our Sun will stay in this mature
phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for
approximately 10 billion years. Stars are fueled by the nuclear fusion of
hydrogen to form helium deep in their interiors.
The
outflow of energy from the central regions of the star provides the pressure
necessary to keep the star from collapsing under its own weight, and the
energy by which it shines.
As
shown in the Hertzsprung-Russell Diagram, Main Sequence stars span a wide
range of luminosities and colors, and can be classified according to those
characteristics. The smallest stars, known as red dwarfs, may contain as
little as 10% the mass of the Sun and emit only 0.01% as much energy, glowing
feebly at temperatures between 3000-4000K.
Despite
their diminutive nature, red dwarfs are by far the most numerous stars in the
Universe and have lifespans of tens of billions of years.
On the
other hand, the most massive stars, known as hypergiants, may be 100 or more
times more massive than the Sun, and have surface temperatures of more than
30,000 K.
Hypergiants
emit hundreds of thousands of times more energy than the Sun, but have
lifetimes of only a few million years. Although extreme stars such as these
are believed to have been common in the early Universe, today they are
extremely rare - the entire Milky Way galaxy contains only a handful of
hypergiants.
Stars
and Their Fates
In
general, the larger a star, the shorter its life, although all but the most
massive stars live for billions of years. When a star has fused all the
hydrogen in its core, nuclear reactions cease. Deprived of the energy
production needed to support it, the core begins to collapse into itself and
becomes much hotter. Hydrogen is still available outside the core, so
hydrogen fusion continues in a shell surrounding the core. The increasingly
hot core also pushes the outer layers of the star outward, causing them to
expand and cool, transforming the star into a red giant.
If the
star is sufficiently massive, the collapsing core may become hot enough to
support more exotic nuclear reactions that consume helium and produce a
variety of heavier elements up to iron. However, such reactions offer only a
temporary reprieve. Gradually, the star's internal nuclear fires become
increasingly unstable - sometimes burning furiously, other times dying down.
These variations cause the star to pulsate and throw off its outer layers,
enshrouding itself in a cocoon of gas and dust. What happens next depends on
the size of the core.
Universe
Stars Helix Nebula
Average Stars Become White Dwarfs For average stars like the Sun, the process of ejecting its outer layers continues until the stellar core is exposed. This dead, but still ferociously hot stellar cinder is called a a White Dwarf. White dwarfs, which are roughly the size of our Earth despite containing the mass of a star, once puzzled astronomers - why didn't they collapse further? What force supported the mass of the core? Quantum mechanics provided the explanation. Pressure from fast moving electrons keeps these stars from collapsing. The more massive the core, the denser the white dwarf that is formed. Thus, the smaller a white dwarf is in diameter, the larger it is in mass!
These
paradoxical stars are very common - our own Sun will be a white dwarf
billions of years from now. White dwarfs are intrinsically very faint because
they are so small and, lacking a source of energy production, they fade into
oblivion as they gradually cool down.
This
fate awaits only those stars with a mass up to about 1.4 times the mass of
our Sun. Above that mass, electron pressure cannot support the core against
further collapse.
If a
white dwarf forms in a binary or multiple star system, it may experience a more
eventful demise as a nova. Nova is Latin for "new" - novae were
once thought to be new stars.
Today,
we understand that they are in fact, very old stars - white dwarfs. If a
white dwarf is close enough to a companion star, its gravity may drag matter -
mostly hydrogen - from the outer layers of that star onto itself, building up
its surface layer. When enough hydrogen has accumulated on the surface, a
burst of nuclear fusion occurs, causing the white dwarf to brighten
substantially and expel the remaining material.
Within
a few days, the glow subsides and the cycle starts again. Sometimes,
particularly massive white dwarfs (those near the 1.4 solar mass limit
mentioned above) may accrete so much mass in the manner that they collapse
and explode completely, becoming what is known as a supernova.
Main
sequence stars over eight solar masses are destined to die in a titanic
explosion called a supernova. A supernova is not merely a bigger nova. In a
nova, only the star's surface explodes.
In a
supernova, the star's core collapses and then explodes. In massive stars, a
complex series of nuclear reactions leads to the production of iron in the
core. Having achieved iron, the star has wrung all the energy it can out of
nuclear fusion - fusion reactions that form elements heavier than iron
actually consume energy rather than produce it. The star no longer has any
way to support its own mass, and the iron core collapses. In just a matter of
seconds the core shrinks from roughly 5000 miles across to just a dozen, and
the temperature spikes 100 billion degrees or more.
The
outer layers of the star initially begin to collapse along with the core, but
rebound with the enormous release of energy and are thrown violently outward.
Supernovae release an almost unimaginable amount of energy. For a period of
days to weeks, a supernova may outshine an entire galaxy. Likewise, all the
naturally occurring elements and a rich array of subatomic particles are
produced in these explosions. On average, a supernova explosion occurs about
once every hundred years in the typical galaxy. About 25 to 50 supernovae are
discovered each year in other galaxies, but most are too far away to be seen
without a telescope.
If the
collapsing stellar core at the center of a supernova contains between about
1.4 and 3 solar masses, the collapse continues until electrons and protons
combine to form neutrons, producing a neutron star. Neutron stars are
incredibly dense - similar to the density of an atomic nucleus.
Because
it contains so much mass packed into such a small volume, the gravitation at
the surface of a neutron star is immense. Like the White Dwarf stars above,
if a neutron star forms in a multiple star system it can accrete gas by
stripping it off any nearby companions.
The
Rossi X-Ray Timing Explorer has captured telltale X-Ray emissions of gas
swirling just a few miles from the surface of a neutron star.
Neutron
stars also have powerful magnetic fields which can accelerate atomic
particles around its magnetic poles producing powerful beams of radiation.
Those beams sweep around like massive searchlight beams as the star rotates.
If such
a beam is oriented so that it periodically points toward the Earth, we
observe it as regular pulses of radiation that occur whenever the magnetic
pole sweeps past the line of sight. In this case, the neutron star is known
as a pulsar.
If the
collapsed stellar core is larger than three solar masses, it collapses
completely to form a black hole: an infinitely dense object whose gravity is
so strong that nothing can escape its immediate proximity, not even light.
Since photons are what our instruments are designed to see, black holes can
only be detected indirectly.
Indirect
observations are possible because the gravitational field of a black hole is
so powerful that any nearby material - often the outer layers of a companion
star - is caught up and dragged in. As matter spirals into a black hole, it
forms a disk that is heated to enormous temperatures, emitting copious
quantities of X-rays and Gamma-rays that indicate the presence of the
underlying hidden companion.
The
dust and debris left behind by novae and supernovae eventually blend with the
surrounding interstellar gas and dust, enriching it with the heavy elements
and chemical compounds produced during stellar death. Eventually, those
materials are recycled, providing the building blocks for a new generation of
stars and accompanying planetary systems.
