Pulsars could help trace how black holes grew in the early universe

پلسارز ابتدائی کائنات میں بلیک ہولز کی نشوونما کا سراغ لگانے میں مدد کر سکتے ہیں

पल्सर शुरुआती ब्रह्मांड में ब्लैक होल के बढ़ने का पता लगाने में मदद कर सकते हैं

Pulsars could help trace how black holes grew in the early universe

Key points

اہم نکات

मुख्य बातें

  • Physicists are looking to pulsars, rapidly spinning neutron stars that send out extremely regular radio pulses, as precise cosmic clocks to study the early growth of black holes.
  • Because their pulses arrive with such steady timing, even tiny shifts can reveal gravitational waves passing through space, including waves left by merging black holes.
  • Separating those signals could help scientists work out how the universe's biggest black holes formed and grew so early, and what else shaped the cosmos in its first moments.
  • طبیعیات دان پلسارز کی طرف دیکھ رہے ہیں، جو تیزی سے گھومنے والے نیوٹران ستارے ہیں اور انتہائی باقاعدہ ریڈیو سگنل بھیجتے ہیں، تاکہ انہیں درست کائناتی گھڑیوں کے طور پر استعمال کر کے بلیک ہولز کی ابتدائی نشوونما کا مطالعہ کیا جا سکے۔ چونکہ ان کے سگنل اتنے باقاعدہ وقت پر آتے ہیں، اس لیے معمولی سی تبدیلی بھی خلا سے گزرنے والی کشش ثقل کی لہروں کو ظاہر کر سکتی ہے، جن میں ضم ہونے والے بلیک ہولز کی لہریں بھی شامل ہیں۔ ان سگنلوں کو الگ کرنے سے سائنسدانوں کو یہ سمجھنے میں مدد مل سکتی ہے کہ کائنات کے سب سے بڑے بلیک ہولز اتنی جلدی کیسے بنے اور بڑھے، اور ابتدائی لمحوں میں کائنات کو اور کیا چیزوں نے شکل دی۔
  • भौतिक विज्ञानी पल्सर की ओर देख रहे हैं, जो तेजी से घूमने वाले न्यूट्रॉन तारे हैं और अत्यंत नियमित रेडियो स्पंदन भेजते हैं, ताकि उन्हें सटीक ब्रह्मांडीय घड़ियों के रूप में इस्तेमाल करके ब्लैक होल के शुरुआती विकास का अध्ययन किया जा सके। चूंकि उनके स्पंदन इतने नियमित समय पर आते हैं, इसलिए मामूली बदलाव भी अंतरिक्ष से गुजरने वाली गुरुत्वाकर्षण तरंगों को उजागर कर सकता है, जिनमें विलय हो रहे ब्लैक होल की तरंगें भी शामिल हैं। इन संकेतों को अलग करने से वैज्ञानिकों को यह समझने में मदद मिल सकती है कि ब्रह्मांड के सबसे बड़े ब्लैक होल इतनी जल्दी कैसे बने और बढ़े, और शुरुआती क्षणों में ब्रह्मांड को और किन चीजों ने आकार दिया।
