WebbThe sudden transformation of the plasma into atoms shortly after the creation caused the electromagnetic radiation ("light) of the primeval fireball to "separate" from the previously Dark universe and shine freely throughout space; this separation is called decoupling in scientific terminology. Webb在物理宇宙学中,大爆炸核合成(缩写为BBN,也称为原始核合成) [1]是除氢的最轻同位素(氢- 1、1 H,具有单个质子作为核)以外的核的产生在宇宙的早期阶段。 大多数宇宙学家认为,原始核合成发生在大爆炸后大约 10 秒到 20 分钟的时间间隔内, [2]据计算,宇宙中大部分氦的同位素 氦 - 4 ( 4 He) 以及少量氢同位素氘 ( 2 H 或 D)、氦同位素氦 - 3 ( 3 …
