At the same time the gamma ray bursts are ejected the collapsing star explodes or goes supernova to the extreme.

Black holes are created when a massive star collapses after running out of fuel and falling inward on its center.

当一颗巨大的恒星燃料耗尽，中心向内塌陷时，就会产生黑洞。

We just say that in textbooks because we don't know what happens when a star collapses into a tiny dot.

我们只是在教科书中这么说，因为我们不知道当一颗恒星坍缩成一个小点时会发生什么。

But when fusion stops, all of a sudden that equilibrium is broken and the star collapses, just like the can.

但当聚变停止时，平衡突然被打破，恒星就会像易拉罐一样坍塌。

A black hole is formed when the core of a star collapses and the star explodes.

当恒星的核心坍缩并且恒星爆炸时，就会形成黑洞。

A supernova occurs when a massive star collapses releasing radio waves, X-rays, cosmic rays and gamma rays into space.

当一颗大质量恒星坍塌向太空释放无线电波、X 射线、宇宙射线和伽马射线时，就会发生超新星爆发。

But when it runs out of fuel, gravity wins and the star collapses, and then explodes with the brightness of a billion suns.

但当它燃料耗尽时，引力占了上风，恒星开始坍缩，接着会发生一场大爆炸，其亮度超过数十亿个太阳。

He says scientists thought that star collapses could not create stellar black holes much bigger than 70 times the mass of our sun.

他说，科学家们认为，恒星坍缩不可能产生比太阳质量大70倍的恒星级黑洞。

They're produced when a star collapses in on itself, creating a point in space where gravity is so strong, even light can't escape from it.

它们是在恒星坍缩的时候产生的坍缩使空间形成一个引力，非常强烈的点以至于光都无法逃脱。

There are " small" ones called stellar black holes. These black holes are formed when a star collapses. They are about the size of a small city.

较" 小" 的黑洞被称为恒星黑洞。这类黑洞是恒星解体时形成的，体积约等于一个小型城市。

It occurred to him that if a star collapsed to the sort of densities found in the core of atoms, the result would be an unimaginably compacted core.

他突然想到，要是恒星坍缩到原子的核心那种密度，便会变成一个极其坚实的核。

When the core of a VERY massive star collapses, forming a black hole, the material just outside the core falls down, forming an incredibly hot swirling maelstrom called an accretion disk.

当一个非常大的恒星的核心坍塌，形成黑洞时，核心外的物质会下降，形成一个非常热的漩涡，称为吸积盘。

When smaller stars collapse into neutron stars though, the newly formed neutron core has a temperature approaching 100 billion degrees which is 6666 times the temperature found inside the sun's core.

不过，当较小的恒星坍缩成中子星时，新形成的中子星核的温度接近 1000 亿度，是太阳核心内温度的 6666 倍。

It occurred to him that if a star collapsed, the atoms that formed its core would be crushed together and their electrons forced into the nucleus to form neutrons.

他突然想到， 如果一颗恒星坍塌，构成其核心的原子将被压碎在一起， 它们的电子被迫进入原子核形成中子。

Well, it might form like a star, collapsing from a gas cloud just like the Sun did 4.6 billion years ago, but instead of turning on and becoming a star, it would simply sit there, cooling.

它可能像一颗恒星一样，从气体云中坍缩，就像46亿年前的太阳一样，但是它并没有变成一颗恒星，它只是待在那里，冷却。
