Cosmic Inflation
Science says Big Bang created the energy of Universe, which was followed by 'Inflation/Expansion' of spacetime, in which spacetime expanded hugely. This is called 'Cosmic Inflation'.Think of a balloon that expands when air is pushed inside. Whatever exists on the surface of balloon uniformly expands along with surface of the balloon. So if energy/matter that was constrained and then expanded, then matter should be seen uniformly spread across the spacetime.
But what we see in Universe today is different. There is a huge AkAsa, empty space of vacuum, everywhere. Then there are clusters of galaxies and matter sprinkled non-uniformly or non-homogenously in this AkAsa.
Baryonic Acounstic Oscillations - praNAva - OmkAra
Science says the current structure of Universe is explained by Baryonic Acoustic oscillations(1) or Cosmic sound. Vedas and Upanishads say it is caused by OmkAra or praNava.The early Universe, was an Universe of hot, dense, plasma of dark matter, baryons, electrons and photons.
This hot, dense plasma with dark matter bends the spacetime it occupies and produces gravitational warping that compresses matter. But the baryons and electrons are charged and the electromagnetic forces repel. Hence they push back the matter.
This is like pebble dropping in a pond. An oscillating wave of photons pushes the baryonic matter to the edges.
Actually it is like multiple pebbles dropping in a pond. Multiple oscillations carried by photons push the matter differently in different directions.
These oscillations are mechanical, acoustic waves or sound waves. These sound waves of photons travelling in multiple directions (as in multiple pebbles being dropped in a pond) aggregate matter differently and create 'anisotropies'. Basically they have aggregate differently in different directions.
These oscillations are called the Baryon acoustic oscillations. They are the praNava. pra means first. Na is 'sound'. PraNava is the first sound produced in the Universe. It is the baryonic acoustic oscillation.
When Universe's spacetime expands due to dark energy, these anisotropies also get inflated along with it. The spaces between the aggregated matter which were smaller in the early Universe, became huge when spacetime expanded hugely. Universe spacetime gets filled with aggregated matter with huge AkAsa or empty space between them.
Again think of a ballon which originally had some ice-cream drops aggregated on it. When this balloon expands, the drops become much far apart.
But the initial anisotropy was created by praNava, the baryonic acoustic oscillations.
PraNava - The basis of matter and beings
The Baryonic Acoustic oscillations or praNAva, creates the accumulated matter, thereby creating the 'gravitational seeds' of galaxies and stars. The molecular clouds that were aggregated became galaxies, spawning several stars. These stars, by different types of stellar nucleo-synthesis created different types of elements and compounds. These also created the planetary systems.Those compounds with carbon then became of basis of long chain molecules, organic seeds of life and living beings.
Thus the praNava, the cosmic sound at the origin is the one responsible for the evolution of matter forms and life. This means no new elements, compounds and life could have formed without this pranAva or OmkAra.
Thus praNava is the beginning of everything in this Universe
pra means first. Na is 'sound'. PraNava is the first sound produced in the Universe. It is the baryonic acoustic oscillation.
PraNava - The OmkAra- The cosmic sound
The Cosmic sound or baryon acoustic oscillations are produced by photons travelling in different directions and aggregating the baryons and electrons, creating anisotropies.When pebbles drop in a pond, it produces 'harmonic' waves. Harmonic waves are waves with a frequency and its positive integer multiples. In this case, matter is pushed towards the edges at a specific rate or the multiple of it.
A simple harmonic wave, to the human ear appears as 'rigkhA' which means motion of a pendulum (which indeed is close to simple harmonic motion). It produces a 'mmmmm..' sound.
The early Universe situation was that photons were pushing the dense baryonic matter in all directions, creating these harmonic motions. At the same time gravitational force (spacetime warping) also acts on the matter and tries to pull them inside. This would have lead to occasional flare-up of matter being pushed back and forth. This is more than harmonics. This is the sound of 'Om' where occasional flare-up sounds are followed by harmonics.
Om-kAra means that which is created by Om. The Universe is indeed Om-kAra, created by OM, or baryonic acoustic oscillations or praNava, the first sound.
Mandukya Upanishad
First verse
Om is the cosmic sound produced by baryonic acoustic oscillations. It is the first acoustic expression or sound and hence called praNava. Since Om is the first acoustic expression produced in the Universe as baryonic acoustic oscillatitons, all our expressions start with Om.
More important, this Om is what created the gravitational seed of galaxies, from which grew the stars, planet and us biological beings. Hence this Om, the first cosmic sound, the pra-Nava, the baryonic acoustic oscillation is the cause of all matter and beings of Universe.
Mandukya Upanishad - Second Verse
Meaning
All of these (Universe) are brahman (evolution). This Atma is brahman/evolution. This evolving/brahman Atma is of four parts.
Third Verse of Mandukya Upanishad
Meaning
Being awake (jAgaritasthAna) the external consciousness (bAhis prajnA) has seven parts (sapta anga), nineteen faces (ekonavinzati mukhah), enjoyed in sthula form (sthUla bhuk) is the vaisvarnarah, which is the foremost/outermost quarter (prathama pAdah).
What is vaisvanara..?
Vaisva-nara means the Universal matter. Nara is the mortal matter. Visva is universe. Vaisva-Nara are those Universal mortal matter forms. These classical matter forms are the 'bAhis prajna'. This is the classical universe that is outside our consciousness. Hence it is bAhis-prajna. Thermodynamics rules this classical Universe.
These matter forms are what we observe. They are the 'sthula' or 'gross' matter form. What we see outside in gross form of matter has seven parts and has 19 faces.
What could be these seven parts and nineteen faces of classical matter forms..?
Fourth verse of Mandukya Upanishad
Fifth verse of Mandukya Upanishad
In Universe's terms it is the state no excitations (kAma) exist. If we go below the quantum nature of particles, there is this state of vacuum energy or state of just a bundle of energy. This was the state of Universe during Cosmic Inflation epoch.
Ananda is not just bliss or happiness. Brhadharanyaka Upanishad says what is Ananda. It is the ability/potential to reproduce. When Universe is in the state of ekibhuta, where only vacuum energy only exist, it has the maximum ability/potential to produce. That is Ananda.
Sixth verse of Mandukya Upanishad
Summary of Mandukya Upanishad
Om is the cosmic sound produced by baryonic acoustic oscillations. It is the first acoustic expression or sound and hence called praNava. Since Om is the first acoustic expression produced in the Universe as baryonic acoustic oscillatitons, all our expressions start with Om.
More important, this Om is what created the gravitational seed of galaxies, from which grew the stars, planet and us biological beings. Hence this Om, the first cosmic sound, the pra-Nava, the baryonic acoustic oscillation is the cause of all matter and beings of Universe.
All of these (Universe) are brahman (evolution). This Atma is brahman/evolution. This evolving/brahman, expression of Atma is of four parts.
The first part is Vaisva-nara. It means the Universal matter. Nara is the mortal matter. Visva is universe. Vaisva-Nara are those Universal mortal matter forms. It is like 'waking up' state of consciousness. Hence it is called 'bAhis prajna'.
