هل ولدت الثقوب السوداء قبل النجوم؟ نقطة حمراء تعيد فتح اللغز

ما يعرفه ريفو عن الخبر

رصد تلسكوب جيمس ويب جسما أحمر قد يحتوي على ثقب أسود بدائي نشأ قبل ولادة النجوم الأولى.
يُعتقد أن الجسم كيو إس أو1 يفتقر للعناصر الثقيلة مما يعزز فرضية نشوئه من تقلبات الكثافة في الكون المبكر.
أظهرت النماذج أن السيناريو الأكثر ترجيحا هو نمو الثقب الأسود عبر ابتلاع الغاز حتى أصبح قادرا على إنتاج الضوء.
لا يعد هذا الاكتشاف تأكيدا نهائيا بل اختبارا لفرضية وجود ثقوب سوداء بدائية قبل ظهور الضوء النجمي.

نقطة حمراء صغيرة في صور جيمس ويب تعيد العلماء إلى اللحظات الأولى للكون، حيث ربما نشأت أجسام غامضة قبل ظهور النجوم. فهل تحمل هذه النقطة الدليل الذي طال انتظاره؟
