Comets may not have delivered life's building blocks to Earth, new study suggests

نئی تحقیق کے مطابق شاید دمدار ستاروں نے زمین پر زندگی کے بنیادی اجزا نہیں پہنچائے

नए अध्ययन के अनुसार शायद धूमकेतुओं ने पृथ्वी पर जीवन के बुनियादी तत्व नहीं पहुँचाए

Comets may not have delivered life's building blocks to Earth, new study suggests

Key points

اہم نکات

मुख्य बातें

  • A new Cambridge study using 100,000 computer simulations suggests comets probably did not deliver the chemical building blocks of life to early Earth.
  • The fragile molecules they may have carried, including hydrogen cyanide, would mostly have been destroyed by the heat and force of high-speed impacts more than four billion years ago.
  • The authors say a successful delivery would have needed a rare one-in-a-million combination of speed and angle, and asteroids remain a possible alternative source.
  • کیمبرج کی نئی تحقیق، جس میں 100,000 کمپیوٹر سمیولیشنز استعمال کی گئیں، بتاتی ہے کہ شاید دمدار ستاروں نے ابتدائی زمین پر زندگی کے کیمیائی بنیادی اجزا نہیں پہنچائے۔ وہ نازک مالیکیولز جو وہ لے کر آئے ہوں گے، جن میں ہائیڈروجن سائینائیڈ بھی شامل ہے، چار ارب سال سے زیادہ پہلے تیز رفتار ٹکراؤ کی گرمی اور قوت سے زیادہ تر تباہ ہو گئے ہوں گے۔ مصنفین کا کہنا ہے کہ کامیاب ترسیل کے لیے رفتار اور زاویے کا نایاب ایک لاکھ میں ایک امتزاج درکار ہوتا، اور سیارچے اب بھی ایک ممکنہ متبادل ذریعہ ہیں۔
  • कैम्ब्रिज के नए अध्ययन, जिसमें 100,000 कंप्यूटर सिमुलेशन का उपयोग किया गया, से पता चलता है कि शायद धूमकेतुओं ने शुरुआती पृथ्वी पर जीवन के रासायनिक बुनियादी तत्व नहीं पहुँचाए। वे नाज़ुक अणु जो वे लाए होंगे, जिनमें हाइड्रोजन साइनाइड भी शामिल है, चार अरब साल से अधिक पहले तेज़ गति वाले टकराव की गर्मी और बल से ज़्यादातर नष्ट हो गए होंगे। लेखकों का कहना है कि सफल डिलीवरी के लिए गति और कोण का दुर्लभ दस लाख में एक संयोजन चाहिए होता, और क्षुद्रग्रह अब भी एक संभावित वैकल्पिक स्रोत हैं।
