黑洞热力学第一定律是什么？
What is the first law of black hole thermodynamics?
黑洞热力学第一定律将质量变化、角动量、电荷与视界面积（熵）和表面引力（温度）联系起来，形式类似普通热力学第一定律。它表明增加黑洞质量或角动量会相应改变其视界面积和表面引力。这一对应揭示了引力量与热力学量之间的深刻关系。
The first law of black hole thermodynamics relates changes in mass, angular momentum, and charge to the horizon area (entropy) and surface gravity (temperature), mirroring the ordinary first law of thermodynamics. It shows that adding mass or spin changes the horizon area and surface gravity accordingly. This correspondence reveals a deep link between gravitational and thermodynamic quantities.

黑洞的熵与贝肯斯坦上限是什么？
What are black hole entropy and the Bekenstein bound?
贝肯斯坦证明黑洞的熵正比于其事件视界面积而非体积，即面积定律，这暗示引力系统的信息容量由边界面积决定。贝肯斯坦上限则给出一个有限区域中可容纳的最大信息量。这些结果深刻影响了全息原理的提出。
Bekenstein showed that a black hole's entropy is proportional to the area of its event horizon rather than its volume, the area law, implying that a gravitational system's information capacity is set by its boundary area. The Bekenstein bound gives the maximum information that can fit in a finite region. These ideas strongly influenced the holographic principle.

黑洞的无毛定理说的是什么，为什么它很重要？
What does the no-hair theorem for black holes state, and why is it important?
无毛定理表明，广义相对论中的稳态黑洞完全由三个可观测量——质量、电荷和角动量——描述，所有其他形成细节（毛发）都会随引力辐射消失。这让黑洞成为可精确建模的简洁物理系统，但也引出了信息悖论等深层难题。
The no-hair theorem states that a stationary black hole in general relativity is completely described by just three observable quantities — mass, charge and angular momentum — with all other formation details (the hair) radiated away. This makes black holes tractable, precisely modeled physical systems, yet it also raises deep puzzles such as the black-hole information paradox.

双黑洞并合如何产生引力波？
How does a binary black hole merger produce gravitational waves?
相互绕转的双黑洞系统不断损失轨道能量，并以引力波形式辐射出去，导致轨道收缩并加快。当二者最终并合时，会释放出极强的引力波脉冲，并在毫秒间转变为单一的克尔黑洞。这一过程已被LIGO于2015年首次直接探测到（GW150914）。
A binary black hole system loses orbital energy by radiating it as gravitational waves, causing the orbit to shrink and speed up. At final merger it releases an intense burst of waves and settles within milliseconds into a single Kerr black hole. This process was first directly detected by LIGO in 2015 as GW150914.

How do Kerr black holes differ from Schwarzschild black holes?
史瓦西黑洞是不旋转、不带电的理想化静态黑洞，只由质量决定。克尔黑洞则描述旋转且不带电的黑洞，由质量和角动量两个参数刻画，并拥有内外两重视界以及一个能层。旋转使克尔黑洞中心的奇点不再是点，而是形成一个环（奇点环）。
A Schwarzschild black hole is an idealized non-rotating, uncharged static black hole determined only by its mass. A Kerr black hole describes a rotating, uncharged hole, characterized by mass and angular momentum, with inner and outer horizons plus an ergosphere. Rotation turns the central singularity from a point into a ring, the ring singularity.

The EHT linked eight radio telescopes around the globe with very-long-baseline interferometry into a virtual telescope the size of Earth, observing at a wavelength of 1.3 mm. By recording and combining the radio waves from the ring of accreting material, it produced the first image of the shadow of M87* in 2019 and of Sagittarius A* in 2022.

黑洞会“蒸发”吗？
Can black holes “evaporate”?
根据霍金在1974年的推导，黑洞视界附近量子效应会令其缓慢辐射粒子，称为霍金辐射。这个过程使黑洞质量逐渐减小，理论上最终会完全蒸发。不过对于恒星级黑洞，蒸发所需时间远超当前宇宙年龄，因此现实中几乎不可观测。
Following Hawking's 1974 derivation, quantum effects near the horizon cause a black hole to emit particles, known as Hawking radiation. This gradually reduces its mass and, in principle, can evaporate it completely. For stellar-mass holes, however, evaporation would take far longer than the present age of the universe, so it is effectively unobservable today.

几乎每一个大型星系的中心都潜伏着一颗超大质量黑洞，其质量可达数百万到数十亿个太阳。例如银河系中心的人马座A*约为四百三十万太阳质量。这些黑洞通过吸积周围物质并与宿主星系共同演化。
Nearly every large galaxy hosts a supermassive black hole at its center, with masses from millions to billions of suns. Sagittarius A*, at the heart of the Milky Way, is about 4.3 million solar masses. These holes grow by accreting surrounding material and co-evolve with their host galaxies.

中子星与黑洞的质量边界在哪里？
Where is the mass boundary between neutron stars and black holes?
由中子简并压支撑的中子星存在最大质量，约在太阳质量的2.2至2.3倍（托尔曼-奥本海默-沃尔科夫极限）。超过这一极限，简并压无法抵抗引力，天体便会坍缩成黑洞。因此致密天体在约2.5至5太阳质量区间形成了一个观测上稀少的“质量鸿沟”。
Neutron stars, supported by neutron degeneracy pressure, have a maximum mass near 2.2 to 2.3 solar masses, the Tolman-Oppenheimer-Volkoff limit. Beyond it, degeneracy pressure fails and the object collapses into a black hole. This leaves an observed paucity of compact objects in the roughly 2.5 to 5 solar-mass gap.

事件视界是什么？
What is the event horizon?
事件视界是黑洞周围的一条假想球面，也是逃逸速度恰好等于光速的边界。任何越过事件视界的物质或信息都无法再传回外界，因此视界之内对我们而言不可直接观测。视界的半径（史瓦西半径）与黑洞质量成正比。
The event horizon is the imaginary spherical surface around a black hole where the escape velocity equals the speed of light. Anything that crosses it can never return information to the outside, so the interior is unobservable from beyond. Its radius, the Schwarzschild radius, is proportional to the black hole's mass.

According to general relativity, the matter at a black hole's center is compressed to a point of zero volume and infinite density, called the singularity. There the spacetime quantities diverge and known physical laws break down. A theory of quantum gravity may be needed to describe what truly happens inside.

吸积盘为什么会发光？
Why does an accretion disk shine?
当气体螺旋落入黑洞时，在吸积盘内因摩擦和引力压缩被剧烈加热到数百万度，从而发出X射线等高能辐射。越靠近黑洞，物质运动越快、温度越高，亮度也越集中。这正是活动星系核和X射线双星明亮的原因。
As gas spirals into a black hole, friction and gravitational compression heat the accretion disk to millions of degrees, emitting high-energy radiation such as X-rays. The closer to the hole, the faster the material moves and the hotter and brighter it becomes. This is why active nuclei and X-ray binaries shine so brightly.

这是一个常见误解。黑洞的引力遵循和普通天体一样的规律，只有在非常靠近视界时引力才极端。如果太阳突然变成同质量黑洞，地球轨道并不会改变，只是失去阳光。只有足够靠近，物质才会被拉入黑洞。
This is a common misconception. A black hole's gravity follows the same rules as any other body, becoming extreme only very close to the horizon. If the Sun suddenly became a same-mass black hole, Earth's orbit would not change, we would just lose sunlight. Matter is pulled in only when it gets close enough.

霍金辐射是斯蒂芬·霍金提出的理论：由于量子涨落，黑洞视界附近会不断产生粒子对，其中一个落入黑洞、另一个逃逸，使黑洞缓慢损失能量。黑洞因此并非完全黑，而是会极其缓慢地蒸发。质量越小的黑洞蒸发越快。
Hawking radiation, proposed by Stephen Hawking, arises from quantum fluctuations near the horizon that continually produce particle pairs, one of which falls in and the other escapes, causing the black hole to slowly lose energy. Thus a black hole is not perfectly black but evaporates extremely slowly. Smaller black holes evaporate faster.

No. A black hole's gravity behaves like that of any normal object at a distance, showing extreme effects only very close in.

How do black holes form?
当一颗质量约为太阳二十倍以上的恒星耗尽核燃料时，核心会在自身引力下急剧坍缩，形成恒星级黑洞。在星系中心，气体和恒星的长期吸积还能造就质量达数百万至数十亿太阳质量的超大质量黑洞。此外，极小质量的原初黑洞也可能诞生于宇宙极早期的密度涨落。
When a star roughly twenty times the Sun's mass exhausts its nuclear fuel, its core collapses catastrophically under its own gravity to form a stellar-mass black hole. At galactic centers, long-term accretion of gas and stars builds supermassive black holes of millions to billions of solar masses. Tiny primordial black holes may also have formed from density fluctuations in the very early universe.
