霍金辐射是什么,它意味着黑洞会消失吗?

What is Hawking radiation, and does it mean black holes can vanish?

霍金辐射是黑洞因量子效应而缓慢向外辐射粒子的过程:在视界附近,真空涨落产生的粒子对中,一个落入黑洞、另一个逃逸,表现为黑洞在“蒸发”。质量越小的黑洞温度越高、蒸发越快,但恒星级黑洞的蒸发极其缓慢。
Hawking radiation is a slow quantum process by which a black hole emits particles: near the horizon, vacuum fluctuations produce particle pairs, one falls in and the other escapes, making the hole appear to “evaporate.” Smaller black holes are hotter and evaporate faster, but stellar-mass holes do so exceedingly slowly.

什么是引力波,黑洞合并如何产生它?

What are gravitational waves, and how do black hole mergers make them?

引力波是时空曲率的涟漪,由大质量天体加速运动产生。2015年LIGO首次直接探测到两个黑洞合并产生的引力波,证实了爱因斯坦的预言,并开启了引力波天文学。
Gravitational waves are ripples in the curvature of spacetime made by violently accelerating masses. In 2015 LIGO directly detected waves from two merging black holes, confirming Einstein's prediction and opening gravitational-wave astronomy.

什么是吸积盘,为什么黑洞周围的物质会发光?

What is an accretion disk, and why does matter around a black hole glow?

当物质落向黑洞时,在视界外形成高速旋转的吸积盘。剧烈的摩擦和引力势能释放把物质加热到数百万度,发出强烈的X射线等高能辐射,使黑洞变得「可见」。
As matter falls toward a black hole, it forms a fast-spinning accretion disk outside the horizon. Friction and released gravitational energy heat it to millions of degrees, emitting intense X-rays and other high-energy radiation that make the black hole "visible."

如何确认银河系中心存在黑洞?

How was the black hole at the Milky Way's center confirmed?

天文学家长期追踪银心附近恒星的轨道,发现它们绕一个约400万倍太阳质量、体积极小的不可见天体运行。这项成果获得2020年诺贝尔物理学奖,该天体即人马座A*。
Astronomers tracked stars near the galactic center for years and found them orbiting an invisible object of about 4 million solar masses in a tiny volume. The work won the 2020 Nobel Prize in Physics; the object is Sagittarius A*.

什么是事件视界和史瓦西半径?

What are the event horizon and the Schwarzschild radius?

事件视界是黑洞的边界,越过它任何物质和信息都无法返回。史瓦西半径是与黑洞质量对应的视界大小,例如太阳若塌缩成黑洞,其视界半径仅约3公里。
The event horizon is the boundary of a black hole; crossing it, nothing can return. The Schwarzschild radius is the horizon's size for a given mass, about 3 kilometers for a black hole with the Sun's mass.

LIGO 在2015年的首次引力波探测发现了什么?

What did LIGO's first gravitational-wave detection in 2015 find?

LIGO 于2015年9月首次直接探测到引力波(事件 GW150914),信号来自约13亿光年外两个约30倍太阳质量的黑洞并合。这一发现证实了爱因斯坦的预言,并开启了“引力波天文学”这一全新观测窗口。
In September 2015 LIGO made the first direct detection of gravitational waves (event GW150914), from the merger of two ~30-solar-mass black holes about 1.3 billion light-years away. It confirmed Einstein's prediction and opened the new window of gravitational-wave astronomy.

黑洞有哪几种主要类型?

What are the main types of black holes?

黑洞按质量主要分为恒星级黑洞(数倍至数十倍太阳质量)、超大质量黑洞(百万至数十亿倍太阳质量,位于星系中心)和中等质量黑洞。原初黑洞目前仍是假说。
By mass, black holes are mainly stellar-mass (a few to tens of solar masses), supermassive (millions to billions of solar masses, found in galactic centers), and intermediate-mass. Primordial black holes remain hypothetical.

人类拍到的第一张黑洞照片是哪一个黑洞?

Which black hole was in the first image ever taken of one?

2019年事件视界望远镜(EHT)公布了室女座M87星系中心超大质量黑洞的首张直接图像。2022年又发布了银河系中心人马座A*的图像。
In 2019 the Event Horizon Telescope released the first direct image of the supermassive black hole at the center of the galaxy M87 in Virgo. In 2022 it also imaged Sagittarius A* at our own galactic center.

史瓦西半径与黑洞的“事件视界”有何关系?

How is the Schwarzschild radius related to a black hole's event horizon?

史瓦西半径由公式 Rs = 2GM/c² 给出,是质量 M 的黑洞的临界半径:若把该质量压缩到这一尺度内,连光也无法逃逸。对于不旋转的黑洞,这个边界就是事件视界,由史瓦西在1916年求得。
The Schwarzschild radius, Rs = 2GM/c², is the critical radius for a mass M: compress that mass inside it and not even light can escape. For a non-rotating black hole this boundary is the event horizon, derived by Schwarzschild in 1916.

恒星级黑洞与超大质量黑洞在质量上有多大差距?

How do stellar-mass and supermassive black holes differ in mass?

恒星级黑洞由大质量恒星坍缩形成,质量通常约3到几十个太阳质量;超大质量黑洞位于星系中心,质量达数百万至数十亿太阳质量。两者之间的“中等质量黑洞”较为罕见,其形成途径仍是活跃的研究方向。
Stellar-mass black holes form from collapsing massive stars and weigh roughly 3 to a few tens of solar masses, while supermassive black holes sit at galaxy centers with millions to billions of solar masses. Intermediate-mass black holes in between are rare, and how they form is an active research area.

事件视界望远镜在2019年取得了什么突破?

What breakthrough did the Event Horizon Telescope achieve in 2019?

事件视界望远镜(EHT)通过联合全球多台射电望远镜进行甚长基线干涉,首次直接拍摄到星系 M87 中心超大质量黑洞的“阴影”与周围发光环的图像。这是人类首次“看见”黑洞视界附近的景象,验证了广义相对论在极端引力下的预言。
The Event Horizon Telescope combined radio dishes worldwide via very-long-baseline interferometry to directly image, for the first time, the shadow and glowing ring around the supermassive black hole in galaxy M87. It was the first time humanity “saw” the region near a black hole's horizon, testing general relativity in extreme gravity.
