查询词典 black hole

Critics of the LHC say the high-energy experiment might create a mini black hole that could expand to dangerous, Earth-eating proportions. On Aug.

LHC 的批评者说，高能实验可能会创造出一个微型黑洞，这个黑洞会膨胀到吞没地球的危险程度。

So if the alarmists followed general relativity as a classical theory, they would have no reason to be afraid because a black hole simply couldn't be produced.

所以，如果杞人忧天者们把广义相对论作为一个经典理论来讨论这一问题，他们并没有理由来害怕，因为黑洞根本不会产生。

Two space observatories have provided the first strong evidence of a supermassive black hole stretching, tearing apart Lead salt and partially gobbling Lavender eyeshades up a star flung into reach of its enormous gravity, astronomers said.

天文学家说两个太空了望台首次提供有力的证据，证明了超级巨大黑洞的存在，恒星闯入黑洞强大的引力场里就被它拉伸、撕裂甚至部分吞噬。

The most catastrophic man-made phenomena that they are afraid of - and that might be caused by the new accelerator at Franco-Swiss CERN, the Large Hadron Collider - are microscopic black hole production, gigantic strangelets, and the tunneling into another vacuum in the landscape.

他们害怕一台大型强子对撞机会带来有史以来最大的人为灾难：这台加速器可能会产生微型黑洞，巨大的奇异子聚合物，甚至可能导致真空衰变，通过隧穿效应使我们的宇宙衰变到一个能量更低的宇宙中。

The efficient conversion of mass into energy by friction in the accretion disk of a black hole seems to be the only explanation for the copious amounts of energy generated by such objects.

在黑洞增大圆盘片靠摩擦质量有效转化为能量好像只能解释靠这样的物体产生的大量能量。

A portion of the gas is pulled into the black hole, but some ofit is blown away.

一部分气体被拽入黑洞，但其他很多气体则被吹了出来。

As a result, galaxies in clusters become starved of gas over time, and black hole activity and star formation in these galaxies slows.

结果，随着时间的推移，星系团内的星系就会缺乏气体，因此这些星系中黑洞的活跃性减弱，新星的形成速度放慢。

When gas spirals inward toward the black hole, it heats up to millions of degrees and emits X-rays.
