The rough English translation of the above Meetei mythological tale of immemorial time goes like this “Once upon a time, the sky was extremely low in such a way that even our hands can touch it! Because of the very low height of the sky, the pestle which was used by our grandparents in pounding the paddy was also touching the sky and had a lot of inconvenience while pounding! Thus, their pestle pushed the sky up suddenly so as to avoid their troubles in pounding the paddy. Then, the sky went up far and high since then……!”
Is it a mere tale! Or is science also encrypted along with the tale! If so, then what is that science! Yes, an insurmountable science on cosmology is being encrypted and is being narrated as tale over ages and over time memorial! Decoding the hidden science is topic of today and dear learned readers please have a look as follows:
What science says on Cosmological models on the origin and fate of the Universe?
Evolution of cosmological models: Cosmology is the study of the universe. It deals with the origin, evolution and fate of the universe. Over centuries, some of the brilliant minds of Philosophers and scientists have tried to develop an understanding of just what the universe is and where it came from, suggesting in the process a bewildering variety of theories and ideas, through various models. However, the most popular and accepted model of the universe, since 1687 to early 20th century, was “the Static Universe” as proposed by Sir Issac Newton in his book “Principia”. The Static Universe is a cosmological model in which the universe is both spatially infinite and temporally infinite, and universe is static, neither expanding nor contracting. Such a universe does not have spatial curvature; that is to say that it is ‘flat’ or Euclidean.
Surprisingly, in 1917 Albert Einstein while solving the equations of his revolutionary General Theory of Relativity (GTR) found that universe is expanding which is contrary to the most popular Static Model at that time! Thus, Einstein had a doubt on his results and did not believe results of his own equations because of the fear of the then scientific community who all were in favour of static universe model. Thus, he introduced a fudge factor called Cosmological Constant to counteract the expansion and concluded that Universe is Static and declared that his theory is in consistent with the Static Universe model.
There comes Olber’s paradox which states that if the universe is eternal and infinite and if it has infinite number of stars, then the night should be bright. But, the night sky is always dark till today. Olber’s paradox literally proved static model of the universe incorrect and paved path for dynamic universe. In early 20th century AD, three profound theories on the origin of the universe were proposed by different scientists i.e. (i) Steady state theory, (ii) Big Bang theory, (iii) Oscillating (pulsating) universe theory.
Steady state theory (flat model) was jointly proposed by Herman Bondi, Fred Hoyle and Thomas Gold, in 1928 and it states that the Universe is the same everywhere and for all time, both in the past and in the future, there is neither beginning nor end to the universe, and it has a constant mean density. Density of galaxies remains more or less constant as it expands (spaces filled in new galaxies).
Big Bang theory (open model) was proposed in 1926 by Georges Lemaitre and coined by George Gamow. Big bang theory says that the universe began about 14 billion years ago from a huge explosion of YLEM and that gigantic explosion is termed as big bang and that moment gave birth to time, space, energy and matter in all directions. About 14 billion years ago, the entire universe was less than an atom, confined to a singularity point which was infinitesimally small, but infinitely hot and dense. In an instant, the universe expanded very quickly in all directions, and then it settled down to a slower rate of expansion, cooling all the time. After a few minutes it had cooled enough for protons to form. It took another 3, 80,000 years to cool enough for hydrogen and helium atoms to form. This allowed light to shine through about 380,000 years after the Big Bang. This early light-sometimes called the “afterglow” of the Big Bang-is more properly known as the cosmic microwave background radiation (CMBR). And subsequently, after 13.8 billion years after Big Bang moment, present universe consisting of large number of galaxies was formed. Density of galaxies falls as universe expands according to big bang model.
The oscillating universe theory (closed model), proposed by Fred Hoyle, believes that the universe began in a giant explosion and is expanding. It states that the universe will continue to expand until the maximum and will then collapse on itself until it comes together in a big “crunch”. In the oscillating universe theory, this cycle would continue indefinitely.
The steady state theory depicts a flat universe as fate of the universe, whereas Big bang theory and Oscillating universe predict Open Universe and Close universe as the fate of the universe.
Birth of Expanding Universe: 12 years later after 1917 when Einstein managed to cheat his equations, in 1929, the American astronomer Edwin Hubble stunned the scientific community by announcing a dramatic discovery that Universe is expanding, but not static. Hubble found that the light coming from the galaxies was shifted towards the red end of the spectrum due to the Doppler effect (known as “redshift”), which indicated that the galaxies were moving away from us. Hubble showed that, in our expanding universe, every galaxy is receding away from us with a speed (V) which is in direct proportion to its distance (D), known as Hubble’s Law (V=HD), where H is Hubble’s constant, inverse of which gives the age of the universe (~13.8 billion years).
Thus, Hubble’s discovery led to abandon the Static Universe model, gave birth of Expanding Universe Model in 1929, and Einstein was also forced to remove his cosmological constant and to announce that introduction of Cosmological Constant as his “Biggest Blunder” he had ever made in his life. Thus, Einstein missed his second Nobel Prize in General Theory of Relativity (GTR) in his life otherwise he could have predicted expanding universe 12 years before Hubble and grabbed Nobel Prize. He landed up his Nobel Prize in Photoelectric Effect in 1921.
Confirmation of Big Bang Theory:
Soon after the confirmation of expanding universe by Gravitational Redshift and Hubble’s findings (equations), scientist started working on the origin and fate of the universe. Now, the next immediate question is – how did universe begin?
If the Universe is expanding, that suggests it used to be smaller and more compact. And if you go back far enough, then there was a moment in the past when all the matter in the Universe was packed into a point and exploded outwards. That moment was the Big Bang. If Big bang really happened, we would be really able to see the remnants of the afterglow of the big bang (CMBR) which was predicted by Ralph Alpher and other scientists in 1948. After the Big Bang, the whole Universe was flooded with incredibly bright light. As the Universe has expanded, that light has been stretched so that it is now microwaves. A microwave telescope can see this ancient light from the very beginning of the Universe. In fact, a view through a microwave telescope shows the whole sky filled with a glow, day and night. Unlike light coming from a star, it is the same wherever you look, and wherever you are. This glow is called the Cosmic Microwave Background radiation (CMBR). CMBR was found only by accident almost 20 years later its prediction, by Arno Penzias and Robert Wilson, both of Bell Telephone Laboratories in Murray Hill, New Jersey, were building a radio receiver in 1965 and begged 1978 physics Nobel Prize for their discovery. The Nobel Prize in Physics 2006 was awarded jointly to John C. Mather and George F. Smoot “for their discovery of the blackbody form and anisotropy of the cosmic microwave background radiation (CMBR).” The cosmic microwave background has been observed on many missions. One of the most famous space-faring missions was NASA’s Cosmic Background Explorer (COBE) satellite, which mapped the sky in the 1990s.
Thus, expanding universe model is experimentally confirmed and Big Bang theory is also confirmed by experimental findings on the remnant signatures of big bang event. Today, expanding universe and big bang is the most accepted and undisputed theory of the universe.
Deciphering the age-old mythological tale!
In the tale-“thaina soraren atiyasi yamna nemlammee – Once upon a time, the sky was extremely low…” means “once upon a time, radius of the universe was very small, universe was very tiny, it depicts about the early or near to big bang event…”. “… fou subada sukna thenglammee – the pestle was also touching the sky…” symbolizes about the “infinitesimally small universe or big bang singularity…(Big Bang Model)”. “…atiyasi sukna khangsu sugatkhi – the pestle pushed the sky up suddenly…” means “…sudden explosion (big bang moment – khangsu sugatpa) has happened and the radius of the universe rapidly increases which also means that the universe got expanded suddenly due a mysterious type internal force (push)… (Expanding Universe Model)” “….adudagi adum atiyasi sum sum wangkhatkhi – then, the sky went up far and high since then……” means “…the universe is expanding since then (big bang event) and is continuing its expansion…(depiction of Open Universe model as fate of the universe)”.
Thus, the paradigm discoveries of Expanding Universe, concept of Big Bang, and Open Universe model as fate of the universe in cosmology were subtly encrypted and narrated in these centuries old Meetei mythogolical tale, which modern science came to know only in 1929 and after…….and this is the beauty of mythological tale…
