Origin of Creation
In the beginning of beginnings,before the orgin of origins,there was no-thing.It was dark,darker than a moonless night,more empty than the desert wastes,quiter than a silent grave.Then this void bought forth a tiny egg of matter and energy.And thus the universe was born .
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
Big bang theory summary
From our current understanding of how the Big Bang might have progressed, taking into account theories about inflation, Grand Unification, etc, we can put together an approximate timeline as follows:
Planck Epoch (or Planck Era), from zero to approximately 10-43 seconds (1 Planck Time).
This is the closest that current physics can get to the absolute beginning of time, and very little can be known about this period. General relativity proposes a gravitational singularity before this time (although even that may break down due to quantum effects), and it is hypothesized that the four fundamental forces (electromagnetism, weak nuclear force, strong nuclear force and gravity) all have the same strength, and are possibly even unified into one fundamental force, held together by a perfect symmetry which some have likened to a sharpened pencil standing on its point (i.e. too symmetrical to last). At this point, the universe spans a region of only 10-35 metres (1 Planck Length), and has a temperature of over 1032°C (the Planck Temperature).
Grand Unification Epoch, from 10–43 seconds to 10–36seconds:
The force of gravity separates from the other fundamental forces (which remain unified), and the earliest elementary particles (and antiparticles) begin to be created.
Inflationary Epoch, from 10–36 seconds to 10–32seconds:
Triggered by the separation of the strong nuclear force, the universe undergoes an extremely rapid exponential expansion, known as cosmic inflation. The linear dimensions of the early universe increases during this period of a tiny fraction of a second by a factor of at least 1026 to around 10 centimetres (about the size of a grapefruit). The elementary particles remaining from the Grand Unification Epoch (a hot, dense quark-gluon plasma, sometimes known as “quark soup”) become distributed very thinly across the universe.
Electroweak Epoch, from 10–36seconds to 10–12 seconds:
As the strong nuclear forceseparates from the other two, particle interactions create large numbers of exotic particles, including W and Z bosons and Higgs bosons (the Higgs field slows particles down and confers mass on them, allowing a universe made entirely out of radiation to support things that have mass).
Quark Epoch, from 10–12 seconds to 10–6 seconds:
Quarks, electrons and neutrinos form in large numbers as the universe cools off to below 10 quadrillion degrees, and the four fundamental forces assume their present forms. Quarks and antiquarks annihilate each other upon contact, but, in a process known as baryogenesis, a surplus of quarks (about one for every billion pairs) survives, which will ultimately combine to form matter.
Hadron Epoch, from 10–6 seconds to 1 second:
The temperature of the universe cools to about a trillion degrees, cool enough to allow quarks to combine to form hadrons (like protons and neutrons). Electrons colliding with protons in the extreme conditions of the Hadron Epoch fuse to form neutronsand give off massless neutrinos, which continue to travel freely through space today, at or near to the speed of light. Some neutrons and neutrinos re-combine into new proton-electron pairs. The only rules governing all this apparently random combining and re-combining are that the overall charge and energy(including mass-energy) be conserved.
Lepton Epoch, from 1 second to 3 minutes:
After the majority (but not all) of hadrons and antihadrons annihilate each other at the end of the Hadron Epoch, leptons (such as electrons) and antileptons (such as positrons) dominate the mass of the universe. As electrons and positrons collide and annihilate each other, energy in the form of photons is freed up, and colliding photons in turn create more electron-positron pairs.
Nucleosynthesis, from 3 minutes to 20 minutes:
The temperature of the universe falls to the point (about a billion degrees) where atomic nuclei can begin to form as protons and neutrons combine through nuclear fusion to form the nuclei of the simple elements of hydrogen, helium and lithium. After about 20 minutes, the temperature and density of the universe has fallen to the point where nuclear fusioncannot continue.
Photon Epoch (or Radiation Domination), from 3 minutes to 240,000 years:
During this long period of gradual cooling, the universe is filled with plasma, a hot, opaque soup of atomic nuclei and electrons. After most of the leptons and antileptons had annihilated each other at the end of the Lepton Epoch, the energy of the universe is dominated by photons, which continue to interact frequently with the charged protons, electrons and nuclei.
Recombination/Decoupling, from 240,000 to 300,000 years:
As the temperature of the universe falls to around 3,000 degrees (about the same heat as the surface of the Sun) and its density also continues to fall, ionized hydrogen and helium atoms capture electrons (known as “recombination”), thus neutralizing their electric charge. With the electrons now bound to atoms, the universe finally becomes transparent to light, making this the earliest epoch observable today. It also releases the photons in the universe which have up till this time been interacting with electrons and protonsin an opaque photon-baryon fluid (known as “decoupling”), and these photons (the same ones we see in today’s cosmic background radiation) can now travel freely. By the end of this period, the universeconsists of a fog of about 75% hydrogen and 25% helium, with just traces of lithium.
Dark Age (or Dark Era), from 300,000 to 150 million years:
The period after the formation of ther first atoms and before the first stars is sometimes referred to as the Dark Age. Although photons exist, the universe at this time is literally dark, with no stars having formed to give off light. With only very diffuse matter remaining, activity in the universe has tailed off dramatically, with very low energy levels and very large time scales. Little of note happens during this period, and the universe is dominated by mysterious “dark matter”.
Reionization, 150 million to 1 billion years:
The first quasars form from gravitational collapse, and the intense radiation they emit reionizes the surrounding universe, the second of two major phase changes of hydrogen gas in the universe (the first being the Recombination period). From this point on, most of the universe goes from being neutral back to being composed of ionized plasma.
Star and Galaxy Formation, 300 - 500 million years onwards:
Gravity amplifies slight irregularities in the density of the primordial gas and pockets of gas become more and more dense, even as the universecontinues to expand rapidly. These small, dense clouds of cosmic gas start to collapse under their own gravity, becoming hot enough to trigger nuclear fusion reactions between hydrogen atoms, creating the very first stars.
The first stars are short-lived supermassive stars, a hundred or so times the mass of our Sun, known as Population III (or “metal-free”) stars. Eventually Population II and then Population I stars also begin to form from the material from previous rounds of star-making. Larger stars burn out quickly and explode in massive supernova events, their ashes going to form subsequent generations of stars. Large volumes of matter collapse to form galaxies and gravitational attraction pulls galaxies towards each other to form groups, clusters and superclusters.
Solar System Formation, 8.5 - 9 billion years:
Our Sun is a late-generation star, incorporating the debris from many generations of earlier stars, and it and the Solar System around it form roughly 4.5 to 5 billion years ago (8.5 to 9 billion years after the Big Bang).
Today, 13.7 billion years:
The expansion of the universe and recycling of starmaterials into new stars continues.
Brahman and Creation According to Vedanta
In the beginning there was nothing.
This was Pursha
Then came Prakrithi (Nature)
She bought Pursha to life.
Together they danced the cosmic dance and the entire universe came into being.
Pure consciousness through its Sankalpa [wish] or will-power projects this creation. Like the spider projects the web and later swallows the web inside. Upanishads mention about this Sankalpa of Brahman - "Akoham Vahusyam - I am one, I will become many".
This Brahman has an inherent wonderful power called Maya-Shakti. This makes him omnipotent. Through this Maya Shakti it projects cosmos. People also call this Maya Shakti as cosmic-mind. So this universe is the Isvara's dream creation - known as Vyavaharika Satya. Each individual also projects its dream world while sleeping - known as Prativashika Satya. And Brahman is known as Paramarthika Satya.So all these in living beings and Universe are in God's dream.
Jiva consists of 24 principle centred around 'I-EGO' or Ahamkara. These 24 principles are Pancha Bhuta, Pancha Tanmatra, Pancha Karmendriya, Pancha Jnanendriya, Manas, Buddhi, Chitta, Ahamkara.Jiva is deluded due to Avidya or ignorance of its true nature Brahman. Each soul is potentially divine. However Jiva forgot it - thinking himself as body-mind complex. This ignorance causes suffering.
Brahman is Satya-Sankalpa. So whatever He imagines manifests into reality or materializes immediately. Brahman is the best artist with excellent imagining capacity or potential. The same does not happen to Jiva due to its limitation. Whatever Jiva thinks it does not materialize into reality.
This creation is Isvara's divine Leela. It is created for divine fun or play. However creation is temporary. It manifests and unmanifests periodically. Brahman is eternal and it sustains creation. It is known as Sat-Chit-Ananda - Existence-Knowledge-Bliss.
Upanishads say - Raso-vai-Sah - He is like nectar. He is the source happiness or bliss.
From one perspective it appears as Nirguna and from another perspective it appears as Saguna for seekers. So the same entity is both Nirguna and Saguna at the same time. Like with full-stomach in waking state, we can feel hungry while dreaming. So both full-stomach and hungry are true at the same time. Nirguna means niskriya [inactive], all attributes appear unmanifested, but it is not powerless. Brahman appears to be devoid of all attributes. Saguna means sakriya [active] with all manifested triguna - Sattva, Rajo, Tamo Guna. Brahman is always associated with its inherent illusion power. We don't consider illusion power or Maya Shakti as separate because it does not have separate existence. Maya is associated with Brahman like a shadow with body.
Yogic Creation Myth :-
Shi-va is the latent unmanifest dimension of reality, generates an energy called Sakthi-an energy that is a consequence not of particles but emptiness, an energy without substance.This energy ignites the void into a dynamic state of creation,maintenance and destruction.Thus emerges the entire realm of time,space,name and form,birth and death.The whole of existence is an eternal and on-going dance between Shiva and Sakthi.
You can think of it like this
Imagine an infinite impenetrable darkness (shiva),to thin infinitesimally, allow that darkness to be a being for the purpose of our story, a gigantic shadow of primal being, containing all cosmic space within him, lost in an unimaginably profound slumber.Out of his navel emerges a flame of energy,fiery orange somewhat feminine in nature.This twisty, serpentine shiver of energy (Sakthi) shoots up high into the void
and since the only way it can function is to become one with him again, it bounces back,deep into his heart. This moment of union with far-reaching consequences.For there arises from the depths of supine being,a ROAR (the primordial vibration,the OM) And our of his mouth erupts a fiery ellipsoidal form that stretches into infinity. This great blast of furious intensity-this primordial roar of creation (OM)-resounds into the farthest reaches of the cosmos. This becomes the first form of Shi-va.This is Rudra (the one who roars).This first form (singular and undifferentiated)-begins to reverberate, there is a spellbinding explosion of sound and light. Galaxies and planets,stars and moons,celestial realms and nether worlds,dimensions of past future, realms both sublte and gross, spew out of the mouth of Rudra,galvanized into life.This is the birth of plurality.Breathtaking plurality. Now begins the vibrancy and dynamism of physical creation.
This,in essence, is the yogic creation story.
