Why you can’t fly a plane to space…?

 

Why can’t you fly a plane to space?

Turns out, you couldn’t even make it halfway. Part of the problem is Earth’s gravity. You need to escape it in order to reach space.

This requires a minimum speed of mach 33 (25,000 mph). The current world record for fastest plane is only mach 6.7 (5,140 mph). The other problem is the atmosphere.

As you fly higher, the atmosphere grows thinner. This creates two serious issues:

Issue 1: Fewer air molecules means it’s harder for the plane to stay airborne.

Issue 2: Less oxygen means less combustible fuel to power the engine.

So how high can planes actually fly? Commercial airliners generally don’t surpass 45,000 feet. But some pilots have pushed their planes to extreme limits.

In 1977, Alexandr Fedotov flew to 123,532 feet. This is the highest any ground-launched plane has reached. Yet, Fedotov only made it about 1/3 the way to space.

Another plane, SpaceShipOne reached 367,500 feet in 2004. It had rocket engines and was flown to an initial 43,500 feet before launch.

Looks like its best to leave spaceflight to the real rocket ships.!!!

Message for the Day…”Do not search for the omnipresent God! Close your eyes and contemplate on the form of God that you like the most. God will manifest before you in that very form. Never think that God is present at one particular place or that distant place only! He is omnipresent everywhere, at all times, and permeates every atom of the universe.”

God has no particular form. Brahma, Vishnu, Maheswara are not different from each other. God manifests in the form His devotees contemplate upon. If a woman considers her husband as God, she can realise God in him. God is present in every human being (Daivam manusha rupena). All are embodiments of the Divine. So to answer the question, “Where is God?”, “God is everywhere.” The Soul (Atma) that is present in you in the form of consciousness is present everywhere and in everyone. Hence do not search for the omnipresent God! Close your eyes and contemplate on the form of God that you like the most. God will manifest before you in that very form. Never think that God is present at one particular place or that distant place only! He is omnipresent everywhere, at all times, and permeates every atom of the universe. Make it your objective in this life to experience that Sweet Lord within yourself!

Message for the Day…” How can you achieve peace? Only through Love! Peace is the fruit of the tree of life; without it, the tree is a barren stump with zero value.”

Source: http://media.radiosai.org

People try to obtain peace by accumulating authority and wealth, which gives them power over others and the ability to command conveniences and comforts which will confer peace. But they quickly realise that both these paths are beset with fear, and the peace that one secures is liable to quick and violent extinction. How then can you achieve peace? Only through Love! Peace is the fruit of the tree of life; without it, the tree is a barren stump with zero value. The fruit is encased within a bitter skin, so that the sweet juice may be preserved and guarded; you must remove the skin to taste its sweetness and to strengthen yourself. The thick rind is symbolic of the six evil passions that encase everyone’s loving heart: lust, anger, greed, attachment, pride and hate. Those who succeed in removing the rind and contact the sweetness within through hard and consistent discipline attain the peace that is everlasting and unchanging.

வாரம் ஒரு கவிதை… ” பிஞ்சு மனங்களும் செல்ல மழையும் “

 

பிஞ்சு மனங்களும்  செல்ல மழையும் 
…………………………………………………………………
 
என் பிஞ்சு கைகளை ஆட்டி  கொஞ்சும்
மழலையில் நான் சொல்லிவிடுவேன் என்ன
வேண்டும் எனக்கு என்று !
எந்த மொழி பேசினாலும்  என் மழலை
மொழி புரியனுமே    என் அம்மாவுக்கும்
அப்பாவுக்கும் !
என் மழலை கேட்டு அம்மா  அப்பா கொட்டும்
செல்ல மழையில்  நனையனும் நான் எப்போதும் !
என் மழலை வயதில் உங்க செல்ல மழை
மட்டுமே  வேண்டும் எனக்கு அம்மா …. அது ஒரு
இனிய தூறல் மழை ! பாசத்தின் சாரல் மழை !
இடி  மழை  எனக்கு வேண்டவே வேண்டாமே
இந்த பிஞ்சு வயதில் …தாங்க முடியுமா நான்
ஒரு இடி முழக்கத்தை இந்த வயதில் ?
புரிஞ்சுக்கணும் ஒரு பிஞ்சின் மனதை நீங்க
செல்ல மழை  பெய்ய வேண்டிய நேரத்தில்
தப்பாமல் பெய்ய வேண்டும் செல்ல மழை !
உங்க மனசு நான் புரிஞ்சு நடக்கும் காலம்
மலரும் நேரம்…. சொல்லாமல்
கொள்ளாமல்  ஓய்ந்து விடும் செல்ல மழை !

Message for the day…”Cultivate good and beneficial feelings and desires. Keep away from bad company and bad thoughts. Realise the holy purpose of life through pure thoughts and words, and selfless service to your fellow-beings.”

Source: http://media.radiosai.org

Why must you compete and quarrel with one another? Nothing in this world can last as such for long. Lord Buddha diagnosed this correctly and declared, “All is sorrow, all is transient, all are but temporary phenomenon of ephemeral characteristics.” Why should you be so animated by these finite objects and petty things? Strive to gain the eternal, the infinite, the universal. One day, you have to give up the body that you have so carefully fed and fostered. How long can you keep all that you have earned and possessed with pride? Trivial thoughts and desires award only sorrow; holy thoughts and desires reward you with divine peace. Therefore cultivate good and beneficial feelings and desires. Keep away from bad company and bad thoughts. Realise the holy purpose of life through pure thoughts and words, and selfless service to your fellow-beings.

Message for the Day…”Lord is everywhere – above, around, below and beside you. For recognising Him, you require not a yantra (machine) but a mantra (mystical potent formula). Dhyana (meditation) is tuning to the exact location of the station, love is the tuning fork. Tune in, realise the Divine and enjoy the bliss He confers!”

Source:http://media.radiosai.org

The Nature around us and with us is the vesture of God, presenting ample evidences of His beauty, goodness, wisdom and power, wherever we look. But the art of recognising Him is strange to us and so we deny Him and live in darkness. We have all around us in the atmosphere the music emanating from various broadcasting stations, but they do not assail your ear at any time. You are not aware of any station. But if you have a receiver, and if you tune it to the correct wavelength, you can hear the broadcast from any particular station; if you fail to tune it correctly, you will get only nuisance instead of news! Similarly the Lord is everywhere – above, around, below and beside you. For recognising Him, you require not a yantra (machine) but a mantra (mystical potent formula). Dhyana (meditation) is tuning to the exact location of the station, love is the tuning fork. Tune in, realise the Divine and enjoy the bliss He confers! 

..Message for the day…”The sky, the stars that twinkle, the Sun and the Moon which illumine the world! Can any ordinary person create these?…”

Source: http://media.radiosai.org

Consider this loudspeaker which has the power to broadcast sound. Someone must have produced it, isn’t it? Who could have created it? Someone with the knowledge and skill to produce such a device. They may not be visible to you, but they exist, perhaps in Germany or Switzerland or Japan. Similarly for everything you enjoy in daily life, be it the television or the watch or any other gadget, there is a creator. But we are also seeing objects which are beyond human capacity. The sky, the stars that twinkle, the Sun and the Moon which illumine the world! Can any ordinary person create these? The supreme power which has the capacity to create such marvellous things has been described by the Vedas as Aprameya, which means, One who is beyond all proofs and all limitations. God cannot be described in words. Your primary objective must be to seek to understand this Infinite Power.

வாரம் ஒரு கவிதை…” சேர்த்து வைத்த கனவு “

 

சேர்த்து வைத்த கனவு…
———————–
காணலாம் கனவு …நீ ..தம்பி.! சேர்த்து வைக்க மட்டும் அல்ல
உன் கனவு ! கனவு நனவாக நீ கட்ட வேண்டும் ஒரு
படிக்கட்டு ..திட்டமிட்டு நீ தாண்டவேண்டும் படிகள் அத்தனையும் !
பெரிதாக யோசி என்று சும்மாவா சொன்னார்கள் நம்
ஆன்றோர்  சான்றோர் ! வானமே உனக்கு எல்லை !
விண்ணில் வெற்றிக்கொடி நாட்ட வேண்டிய  நீ
இந்த மண்ணில் ஒரு வட்டத்தில் மட்டும் சுழல வேண்டுமா ?
தன் கூடுதான் தன் உலகம் என்று ஒரு பறவை நினைத்தால்
இந்த மண்ணிலிருந்து விண்ணில்  அது பறப்பது எப்படி ?
சிறகடித்து பறக்கும் அந்த பறவையைப் பார்த்து நீ
கற்றுக்கொள்  தம்பி..இந்த மண்ணில் மட்டும் அல்ல
விண்ணிலும் வெற்றிக் கொடி நாட்டப் பிறந்தவன் நீ என்று !
உன் கனவு எல்லாம் நனவாக வேண்டுமே அல்லாமல்
சேர்த்து வைத்து மறக்க அல்ல  உன் கனவு !  பார்த்து
நடக்க வேண்டும் தம்பி நீ ! கடக்க வேண்டும் தடைக்
கற்களையும் உன் வெற்றிப் படிகளாக்கி !
வானமே உனக்கு எல்லை …இல்லை உனக்கு
எதுவும் தொல்லை என்று நடுவில் !

Message for the Day…”When action (Karma) is done as dedication and Upasana (worship) is done as essential for very life, the fog of intelligence melts and disappears revealing the truth. Karma, when engaged in as dedicated to God, loses its evil effects for the doer leaving the consequence to God!”

Source:http://media.radiosai.org/

Intelligence is a double-edged sword. It can cut chains and liberate you; it can cause fatal wounds and kill. Hence the great Gayatri Mantra prays to God to preside over the intelligence and render it beneficial to individuals and society. The education of the emotions and the control of passions are both part of Yoga, the spiritual discipline that purifies the intelligence. To penetrate the thick fog that ignorance spreads over Reality, intelligence must be built on the basis of virtues. When action (Karma) is done as dedication and Upasana(worship) is done as essential for very life, the fog of intelligence melts and disappears revealing the truth. Karma, when engaged in as dedicated to God, loses its evil effects for the doer leaving the consequence to God! Moreover, as every act is considered as an act of worship, it is done to the best of one’s ability transmuting mundane Karma into worship.
