நான் யார் தெரியுமா ! - பல மனிதர்கள், அகங்காரத்துடனும் ஆணவத்துடனும் ஆத்திரம் கொப்பளிக்க கேட்கும் கேள்வி !?
என் கண்மணி, உன் காதலி, இள மாங்கனி,
உன்னை பார்த்ததும் சிரிக்கின்றதேன்
என சிவகுமாரும் சுமித்ராவும் சிகப்பு வண்ண பல்லவன் பஸ்ஸில் டூயட் பாட, 'தேனாம்பேட்டை சூப்பர் மார்க்கெட் இறங்கு' என கண்டக்டர் குரல் கூட ஒலிக்க - இளையராஜா இசையில் ஒலித்த பாடல் இடம் பெற்ற படம் 'சிட்டுக்குருவி". நாம் அன்றாடம் காணும் இந்த பறவை - சிட்டு குருவி - சிட்டுக்குருவி ஒரு சிறிய பறவை !
சிறியது - நாம் காணும் உயிரினங்களில், நம்மை விட மிக சிறிய உடற்கூறு படைத்தது இந்த பறவை. ஒவ்வொரு மனிதனும் அன்றாட வாழ்க்கையில் உண்டு உறங்கும் போது தன்னைப் பற்றிய நினைவு இருப்பதில்லை, ஆழ்ந்த உறக்கத்தில் மறந்தும் விழித்த பின் "நான்" "எனது" உணர்வு உதிக்கிறது. உறங்கும் போது "நான்" என்கிற உணர்வு எங்கே போகிறது. ஆனால் தான் பிறர் முன்னிலையில் பெரியவர் என்று காட்டிக்கொள்ள கேட்கும் கேள்வி, வெளிப்படும் மனோநிலை தான் - "நான் யார்" ?
Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
In ‘Crazy thieves in Palavakkam’ drama – a middle class family (in 1970s) would build a small house in the outskirts of Chennai in an area called Palavakkam (now a richman’s place) - they would be gleeful when they see another house in distance and more so, when an odd man walks on the street ! ~ who lives next door ? 0r whether there is life nearby has always a great curiosity of mankind !!
So is there life nearby ! – in the nearest gruha (not as nearby home but nearby galaxy !) .. .. a Galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. Galaxies range in size from dwarfs with just a few hundred million (108) stars to giants with one hundred trillion stars, each orbiting its galaxy's center of mass.
Man is a tiny tot in earth .. to understand how big is Universe, we need to understand its size. The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. Initially, it was estimated that there may be 2 trillion galaxies in the observable universe. That number was reduced in 2021 to only several hundred billion based on data from New Horizons
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).
Currently, the area of Chennai is 1,189 sq km, India covers an area of 32,87,263 sq. km, extending from the snow-covered Himalayan heights to the tropical rain forests of the south. Earth's widest point is the equator, which runs across the planet's center at zero degrees latitude. According to NASA, Earth's radius at the equator is 3,963 miles (6,378 kilometers), while the radius at the poles is 3,950 miles (6,356 km). The surface area of Earth is about 197 million square miles (510 million square kilometers). Earth is the fifth-largest planet in the solar system, behind Jupiter, Saturn, Uranus and Neptune. With a diameter of 86,881 miles (139,822 km), Jupiter — the largest planet in the solar system — is 11 times wider than Earth.
Our earth is a tiny tot in the Universe, part of a galaxy. For starters, the Milky Way is really, really big! Not only does it measure some 100,000–120,000 light-years in diameter and about 1,000 light-years thick, but up to 400 billion stars are located within it !!! our galaxy is only a middle-weight when compared to other galaxies in the local Universe. Andromeda, the closest major galaxy to our own, is about twice as large as our own. It measures 220,000 light years in diameter, and has an estimated 400-800 billion stars within it.
Well somewhere I lost track of comparison – and yet we call others tinytots!! - some stray thoughts from Aasami Sirippu Sinthanaiyaan on a rainy Sunday !
