All you need to know is that Black Holes are made of a Nutella Nougat like substance except a whole lot unhealthier for you. [57] The temperature of this thermal spectrum (Hawking temperature) is proportional to the surface gravity of the black hole, which, for a Schwarzschild black hole, is inversely proportional to the mass. The answer to "what is a black hole made of," is that it is made of nothing but energy. 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 usual standard explanation is that the black hole retains only space-time location, charge, angular momentum and mass. [114] A variation of the Penrose process in the presence of strong magnetic fields, the Blandford–Znajek process is considered a likely mechanism for the enormous luminosity and relativistic jets of quasars and other active galactic nuclei. I haven't the slightest idea what I'm talking about! In quantum mechanics, loss of information corresponds to the violation of a property called unitarity, and it has been argued that loss of unitarity would also imply violation of conservation of energy,[200] though this has also been disputed. [195], One puzzling feature is that the entropy of a black hole scales with its area rather than with its volume, since entropy is normally an extensive quantity that scales linearly with the volume of the system. Micro black holes are thought to be primordial black holes. [115] The location of the ISCO depends on the spin of the black hole, in the case of a Schwarzschild black hole (spin zero) is: and decreases with increasing black hole spin for particles orbiting in the same direction as the spin. It is restricted only by the speed of light. Your opinions are important to us. In the end, your suggestion that matter is not “destroyed” when it enters a black hole but just becomes unobservable to us, is plausible. Astronomy & Space Exploration, and Others: Since the release of the Event Horizon image, Ive been considering the long debated question of what are black holes made of. Lifecycle hooks in extended LWC fail if Base LWC called connectedCallback. This is thought to have been important, especially in the early growth of supermassive black holes, which could have formed from the aggregation of many smaller objects. [186] One possibility for observing gravitational lensing by a black hole would be to observe stars in orbit around the black hole. The dark shadow in the middle results from light paths absorbed by the black hole.

Stars passing too close to a supermassive black hole can be shred into streamers that shine very brightly before being "swallowed. According to quantum field theory in curved spacetime, a single emission of Hawking radiation involves two mutually entangled particles. [36][37][38][39][40], Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius as indicating that this was the boundary of a bubble in which time stopped. By studying the companion star it is often possible to obtain the orbital parameters of the system and to obtain an estimate for the mass of the compact object. This means that the black hole has mass (which we can measure by its gravitational field) and a size (which looks to us as the diameter of its event horizon) but it doesn't possess density in the same way a baseball or a planet does. [43], These results came at the beginning of the golden age of general relativity, which was marked by general relativity and black holes becoming mainstream subjects of research. rest of the universe, and where light cannot escape. [163] Since then, one of the stars—called S2—has completed a full orbit. Tom. However, a minority of relativists continued to contend that black holes were physical objects,[118] and by the end of the 1960s, they had persuaded the majority of researchers in the field that there is no obstacle to the formation of an event horizon. That black hole has a mass equal to six and a half billion Suns but is only 38 billion km (24 billion miles) across. How Big is a Black Hole? This seemingly creates a paradox: a principle called "monogamy of entanglement" requires that, like any quantum system, the outgoing particle cannot be fully entangled with two other systems at the same time; yet here the outgoing particle appears to be entangled both with the infalling particle and, independently, with past Hawking radiation. Arguably, the ringdown is the most direct way of observing a black hole. That the ~skin~ is actually all there is, a holographic N-1 projection of its genesis and its nature. What is the lowest level character that can unfailingly beat the Lost Mine of Phandelver starting encounter? Kevin Croker, a postdoctoral research fellow in the Department of Physics and Astronomy, and Joel Weiner, a faculty member in the Department of Mathematics, have shown that this assumption can fail for the compact objects that remain after the collapse and explosion of very large stars. But there appears to be a lower limit to the mass a star needs to be to produce a black hole. Click here to sign in with These solutions have so-called naked singularities that can be observed from the outside, and hence are deemed unphysical. Stellar-mass or larger black holes receive more mass from the cosmic microwave background than they emit through Hawking radiation and thus will grow instead of shrinking. But from a physical perspective, they must be made of something. [5][6] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. Firstly, the force of gravitation would be so great that light would be unable to escape from it, the rays falling back to the star like a stone to the earth.
