Bardeen and Brandon Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics. The shape of the event horizon of a black hole is always approximately spherical. On the other hand, indestructible observers falling into a black hole do not notice any of these effects as they cross the event horizon.

It's possible that a President Kerry could reward his firefighter backers by pouring endless federal dollars down a black hole. Because a black hole has only a few internal parameters, most of the information about the matter that went into forming the black hole is lost. This behavior is so puzzling that it has been called the black hole information loss paradox. Therefore, Bekenstein proposed that a black hole should have an entropy, and that it should be proportional to its horizon area. For example, a charged black hole repels other like charges just like any other charged object. However, such alternatives are typically not stable enough to explain the supermassive black hole candidates. For example, a supermassive black hole could be modelled by a large cluster of very dark objects.

Finkelstein's solution extended the Schwarzschild solution for the future of observers falling into a black hole. If such a system emits signals that can be directly traced back to the compact object, it cannot be a black hole. If there are other stars orbiting a black hole, their orbits can be used to determine the black hole's mass and location. In November 2011 the first direct observation of a quasar accretion disk around a supermassive black hole was reported. The Hawking radiation for an astrophysical black hole is predicted to be very weak and would thus be exceedingly difficult to detect from Earth. Even a black hole that is heavy compared to a human would evaporate in an instant. If a black hole is very small, the radiation effects are expected to become very strong. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. In many ways a black hole acts like an ideal black body, as it reflects no light. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. Another possibility for black hole growth, is for a black hole to merge with other objects such as stars or even other black holes. Thus, it produced not a black hole event horizon, but its opposite, called a white hole. Any black hole will continually absorb gas and interstellar dust from its surroundings and omnipresent cosmic background radiation. In February 2016, the Advanced LIGO team announced that they had detected gravitational waves from a black hole collision. Primordial black holes could thus account for the creation of any type of black hole. This energy is taken from the rotational energy of the black hole causing the latter to slow.

In 1963, Roy Kerr found the exact solution for a rotating black hole. In this period more general black hole solutions were found. This means that there is no observable difference between the gravitational field of such a black hole and that of any other spherical object of the same mass. Most of this gravitational radiation is emitted in one direction, pushing the merged black hole system in the opposite direction, like the kickback from a shotgun. Regardless of the type of matter which goes into a black hole, it appears that only information concerning the total mass, charge, and angular momentum are conserved. This object is an active giant radio galaxy with a super-massive black hole, known as Fornax A, which has been feeding on a remnant it cannibalised. The presence of an ordinary star in such a system provides a unique opportunity for studying the central object and to determine if it might be a black hole. Matter that falls onto a black hole can form an external accretion disk heated by friction, forming some of the brightest objects in the universe. Recently reported distances range from 4 to 29 megaparsecs, but using this new method the researchers calculated the distance of 19 megaparsecs to the supermassive black hole. When the accreting object is a neutron star or a black hole, the gas in the inner accretion disc orbits at very high speeds because of its proximity to the compact object. The proper motions of stars near the center of our own Milky Way provide strong observational evidence that these stars are orbiting a supermassive black hole. Arguably, the ringdown is the most direct way of observing a black hole. At the center of a black hole, as described by general relativity, lies a gravitational singularity, a region where the spacetime curvature becomes infinite. Show More Sentences This seemingly causes a violation of the second law of black hole mechanics, since the radiation will carry away energy from the black hole causing it to shrink. The finding shows that whatever is driving blazar jets operates right near the central black hole, which can weigh in at millions or billions of times the mass of the sun. The size of a black hole, as determined by the radius of the event horizon, or Schwarzschild radius, is roughly proportional to the mass M through. In 1970, Hawking postulated what became known as the second law of black hole dynamics, that the event horizon of a black hole can never get smaller. Another way that the black hole nature of an object may be tested in the future is through observation of effects caused by a strong gravitational field in their vicinity. By applying quantum field theory to a static black hole background, he determined that a black hole should emit particles that display a perfect black body spectrum. Gas tightly bound to an ejected black hole would stay with the hole and rotate rapidly, producing a broad emission line showing up as a fat rather than narrow peak.

Similarly, the total mass inside a sphere containing a black hole can be found by using the gravitational analog of Gauss's law, the ADM mass, far away from the black hole. This radiation does not appear to carry any additional information about the matter that formed the black hole, meaning that this information appears to be gone forever. While light can still escape from the photon sphere, any light that crosses the photon sphere on an inbound trajectory will be captured by the black hole.
