The deepest X-ray image of the sky shows that black holes are aggressively growing by 800 million years after the Big Bang.
钱德拉深空X线图像显示，在宇宙大爆炸后仅仅8亿年，黑洞就开始饕餮暴长。
The new results show there were at least 30 million black holes before the Universe was a billion years old.
新研究显示，在宇宙仅仅10亿岁时，就存在至少3000万个黑洞
The stronger signal in high-energy X-rays implies that the black holes are nearly all enshrouded in thick clouds of gas and dust.
高能X线的强信号意味着这些黑洞几乎都被浓密的气体尘埃包裹着（那时的宇宙其实几乎没尘埃，这些写文章的人习惯了——G版注）

X射线波长很短是不能穿透大气的。但他携带的信息量很大。波长越短信息量越大。
