With regard to the creation of the universe (heavens and the earth) Allah (SWT) says in the Qur'an: 

Your Guardian Lord

Is God, Who created

The heavens and the earth (universe)

In six Days,  ..............

                    Surah, A'RAF, 7:54 or 32: 4

 

Literal translation gives the impression that the universe was created in six Days.  The Arabic word "Yaum" is translated as Day.  Actually a 'day' of the people living on earth is the time interval between each sunrise. During this time the earth makes one complete rotation around its axis, while moving in an orbit around the sun (which is a star).  In this verse Allah (SWT) is referring to the conditions, which existed before the sun or earth, were created.  Hence the 'six days' should not be interpreted in terms of earth days.  For Allah "yaum" is equal to billions of years or as short as one hundredth of a second or one atto-micro second (10-18 X 10-6 = 10-24 second). The relativity of time is mentioned in the Qur'an Hakeem (The Book of Wisdom) in several verses. It is pertinent here to quote Abdullah Yusuf Ali, the most popular translator of the Noble Qur'an in the English language with commentaries.  In note 1031 he says, " The creation in six Days is of course metaphorical.  The " Days of God" refer not so much to time as to the growth in us of a spiritual sense, a sense of sin and a sense of God's Mercy.  In Surah, 22: 47, we are told that a Day in the sight of God is like a thousand years of our reckoning and in Surah, 70: 4; the comparison is with 50,000 years of our (earth) years.  In the history of our material earth, we may reckon six great epochs of evolution." 

     Hence the concept of time is relative.  The meaning of "Yaum" includes day, period of time, interval of time, age, era, epochs of evolution or Time Frame. 

     The following article describes the creation of the universe in six periods of time or "Time Frames".  This description is based on a theory of the early universe, which is popularly known by astronomers as the "standard model."  It is more or less same thing as the "Big Bang" theory except that it contains the detailed recipe for the contents of the universe. 

    At the end of the article a Glossary of technical words is provided so that the readers may refer to it in order to understand the meaning of the word. 

At the beginning, time was zero and space was zero and the temperature was infinite.  Einstein showed through his famous equation (E = mc2) that mass can be converted into energy and energy can be converted into mass.  Heat is energy, and from energy particles of mass could be produced.  Above a threshold temperature of one billion degrees Kelvin (0 Celsius is equal to 2730 Kelvin), the universe would have contained a large number of particles called pi mesons.  Their mass is about one-seventh that of a nucleon (proton or neutron). Nucleon is a particle that exists in the nucleus of an atom. A proton is a positively charged nucleon, whereas a neutron is slightly heavier than the proton but is electrically neutral.  Unlike other particles, pi mesons interact very strongly with each other and with the nucleons.  The interaction of pi mesons with the nucleons or nuclear particles is responsible for the nuclear or attractive force that exists in the nucleus of an atom. 

     The behavior of matter at super-high temperature is very difficult to predict.  Hence the interpretation of the creation of the universe starts about one-hundredth of a second after the beginning (Big Bang) and the temperature was one hundred billion degrees Kelvin (0 Celsius is equal to 2730 Kelvin).

 

FIRST DAY:

 

    At this time the temperature of the universe is one hundred billion degrees Kelvin (1011 K).  It is filled with particles and radiation, which cannot be differentiated.  The particles, which are continually being created out of pure energy, are colliding with each other very rapidly.  Although the universe is expanding rapidly, the universe appears to be in a state of thermal equilibrium.  The contents of the universe are subject to the laws of statistical mechanics.  The temperature is extremely hot (1011   K) and the conserved quantities of particle physics such as charge, lepton number, baryon number-are extremely small or zero.

 

     The particles that are present abundantly are the electron (the negatively charged particle that flows through wires in electric currents and makes up the outer parts of all atoms and molecules in the present universe) and positron (antiparticle of electron which is a positively charged particle with precisely the same mass as electron).  In the present universe positrons are found only in high-energy laboratories, in some kinds of radioactivity, and in violent astronomical phenomena like cosmic rays and supernovas, but in the early universe the number of positrons was almost exactly equal to the number of electrons, the massless particles- the photons, neutrinos and antineutrinos (antiparticle of neutrino).  Neutrinos are ghostly particles with no mass or electric charge.  At this time the universe is extremely dense and even the neutrinos, which can travel through the earth or through lead bricks without being scattered, are in a state of thermal equilibrium with electrons, positrons, and photons by colliding with them rapidly and with each other.  They are behaving just like so many different kinds of radiation.  The energy density is calculated to be 21 X 1044 electron Volts per liter.  This is equivalent to a mass density of 3.8 billion kilogram per liter or to express in simple term's equivalent to 3.8 billion times the density of water under normal earth conditions.  Nobody has any concept of what this huge density means.  Suppose Mount Everest was made of matter this dense, its gravitational attraction would destroy the earth.  At this time the universe is filled with light.

 

     The universe on the 'first day' is rapidly expanding and cooling.  There are a small number of nuclear particles (nucleons) at this time.   About one nucleon (proton or neutron) for every one billion (109) photons or electrons or neutrinos.  The neutron is slightly heavier than the proton.  The few neutrons or protons are colliding with the abundant electrons, positrons, and so on. As a result of these collisions a proton is converted into a neutron and vice versa.  The reaction can be written as:

Proton + antineutrino = neutron  + positron (vice versa) 

Neutron + neutrino = proton + electron (vice versa) 

 There are almost exactly the same number of neutrinos and antineutrinos, the same number of electrons and positrons, so that the transition from neutron to proton is as fast as the transition from proton to neutron.  Because of equilibrium the number of neutrons is equal to the number of protons on the 'first day.'  These nucleons are not yet bound into nuclei and any complex nuclei formed are destroyed as soon as they are formed. 

    One is tempted to ask the question how large was the universe on the 'first day.'   Unfortunately no one has the answer and this question has no meaning.  If one shows that the universe is infinite now, then one can argue that the universe was Infinite then (at the time of 'first day), and will always be Infinite.  On the other hand it is possible that the universe now has a finite circumference, which is estimated to be about 125 billion light years.  This estimate is based on the present value of the Hubble Constant.  By taking the ratios of the temperature then (1011 K) to the present temperature (3 K), the circumference of the universe on the 'first day' is calculated to be about four light years (A light-year is the distance traveled by light in one year at the rate of 300 million kilometers per second).  The details of the story of cosmic evolution (birth and formation of the universe) in the beginning do not depend on whether the circumference of the universe was infinite or had only a few light years.

 

SECOND DAY 

Since the 'first day' only eleven hundredths of a second (0.11 sec.) have elapsed.  The temperature of the universe has come down (cooled) to 30 billion degrees Kelvin (3X1010 K).  Qualitatively nothing has changed- the contents of the universe are the same such as protons, neutrons, electrons, positrons, neutrinos, antineutrinos and photons, -all in thermal equilibrium. The energy density has dropped to about 30 million times the energy density contained in the rest mass of water.  The expansion time of the universe has now lengthened to about two-tenths of a second (0.2 second).  The few nucleons (neutrons or protons) are not bound into nuclei, but with the cooling of temperature it is now significantly easier for the heavier neutrons to transform into lighter protons than vice versa.  The ratio of neutrons to protons or nuclear particle balance has shifted to one-third neutrons and two-thirds protons.

 

THRID DAY 

     Since the 'first day' a little over one-second (1.09 seconds) have elapsed. The temperature of the universe is now ten billion degrees Kelvin (1010  K). The decreasing density and temperature have caused the neutrinos and antineutrinos to behave like free particles and they are no longer in thermal equilibrium with the electrons, positrons or photons.  This is called the "decoupling" of the neutrinos and they expand freely.  They do not play any active role in the formation of the universe, except that their energy will continue to provide part of the source of the gravitational field of the universe. 

    The energy density is now reduced to a mass density of 380,000 times that of ordinary water.  The temperature of the universe is twice the threshold temperature of electrons and positrons.  The electrons and positrons interact with each other to annihilate more rapidly than they can be created out of radiation (energy).  The temperature of the universe is still too hot for neutrons and protons to be bound into atomic nuclei for any appreciable length of time.  The cooling temperature has now allowed the neutron-proton balance to shift to one-quarter neutrons and three-quarter protons.

 

FOURTH DAY 

Since the 'first day' about 14 seconds have elapsed.  The temperature of the universe is now 3 billion (3 X 109 K) degrees Kelvin.  The electrons and positrons are beginning rapidly to disappear as major components of the universe.  The neutrinos are about 8 percent cooler than the electrons, positrons, and photons.  Here afterwards the temperature of the universe means the temperature of the photons. 

The temperature is cool enough for the formation of stable nuclei such as helium (4He), however this does not occur immediately.  Now, ordinary helium (He4) is a tightly bound nucleus.  On the other hand the isotope (an atom having the same number of protons but different number of neutrons) of hydrogen, tritium (3H), and an Isotope of Helium- helium-3 (3He) are much less tightly 2 bound, and heavy hydrogen or deuterium (2H) is especially loosely bound. (It requires about one-tenth as much energy to pull a deuterium nucleus (which contains one proton and one neutron) apart as to pull a single nucleon out of helium nucleus containing two protons and two neutrons).  On the 'fourth day' with a temperature of three billion degrees Kelvin, nuclei of deuterium (heavy hydrogen) are blasted apart as soon as they form and there is no chance for the formation of heavier nuclei.  Neutrons continue to be transformed into protons, but at a much slower rate than before.  The neutron-proton balance is about one-fifth neutrons to four-fifth protons.

 

FIFTH DAY 

Since the 'first day' three minutes and two seconds have elapsed.  The temperature of the universe is now one billion degrees Kelvin (10K), just about 70 times hotter than the temperature at the center of the sun.  The main components of the universe are now photons, neutrinos, and antineutrinos as the electrons and positrons have mostly disappeared.  When electron-positron pair annihilate energy is released which increases the temperature of the photons by 35 percent more than that of the neutrinos. 

     The temperature of the universe is cool enough so that the nuclei of normal helium (Helium-4), helium-3, and tritium hold together.  One should remember that when a neutron is free (not bound in the nucleus) it decays after 920 seconds or about 15 minutes and becomes a proton.  The collision between neutrons and protons with electrons, neutrinos, and their antiparticles have now come to a stop, but the decay of the free neutron is beginning to be important. The neutron-proton balance is now one-seventh neutrons and six-sevenths protons.  This period is called  "era of nucleosynthesis", as neutrons are rapidly assembled into helium nuclei, and the neutron-proton ratio is frozen at the value it has at that time.

 

SIXTH DAY 

Since the 'first day' more than half-an-hour or 34 minutes and 40 seconds have elapsed.  The temperature of the universe is now 300 million degrees Kelvin or 21 times hotter than the temperature at the center of the sun.  Except for the small excess of electrons required to balance the charge of the protons, the electrons and positrons are now completely annihilated.  The energy density of the universe is now equivalent to a mass density one-tenth that of ordinary water; of this one-third is in the form of neutrinos and antineutrinos and two-third is in the form of photons. Nuclear processes have ceased, so that the nucleons are mostly either bound into helium nuclei or are free protons (nuclei of hydrogen atoms).  There is one electron for each free or bound proton.  Since the universe is too hot, stable atoms cannot hold together. 

     For about one million years, the universe goes on expanding and cooling without anything happening.  At that time the temperature would have cooled to the point where electrons and nuclei can form stable atoms.  Due to lack of free electrons in the contents of the universe, the universe becomes transparent to radiation.  This era is known as the "Decoupling Era" - decoupling of matter and radiation.  The electron and-protons combine to form hydrogen and helium gases.  The resulting gas would begin under the influence of gravitation to form clumps, which would ultimately condense to form galaxies and stars of the present universe.  After another 10 billion years later intelligent beings will emerge to postulate the story of the origin of the universe.
