Where does a black hole lead to12/12/2022 Whatever is inside the event horizon is sealed off forever from the space-time of outside observers. The spherical surface defined by this radius is termed the event horizon of the black hole because events inside the event horizon can have no effect on events outside it. Essentially, there are no straight lines connecting any point that is within a certain radius of a black hole (which, in theory, means there is no dimension) to any point that is farther away. Within a certain radius of a black hole, all geodesics are so warped that a photon of light cannot escape to another part of the universe. Furthermore, gravity warps space, bending geodesics the stronger a gravitational field is in a certain region, the more bent the geodesics are in that region. The event horizonĪccording to general relativity, the path taken by a beam of light is the shortest distance between two points such a path is called a geodesic. In recent decades, much observational evidence has been gathered to support the existence of black holes there is no debate among astronomers today about whether black holes exist, only regarding their precise properties. The theory of general relativity, put forward by German physicist Albert Einstein (1679 –1959) in 1915 and today basic to physicists ’ understanding of the universe, also predicts the existence of black holes, though on from rather different reasoning. French mathematician Pierre Simon Laplace (1749 –1847) reasoned in 1795 that if the corpuscular theory of light proposed by English physicist Isaac Newton (1642 –1727) were correct, there could exist massive objects from which light could not escape. Black holes can (and some do) contain very large amounts of matter -millions or billions of times the mass of the sun -but may be formed by even a small amount of matter sufficiently compressed. If the Earth were compacted so that it had the same mass, but half its present radius, the force of gravity at its surface would be four times as great as it is now if it were compacted further, a density would eventually be reached at which its constituent subatomic particles would be unable to support their own weight and would collapse to a state of (theoretically) infinite density, producing a black hole. The more matter is contained in an object and the smaller its volume -in other words, the higher its density -the more intense the gravitational field at its surface will be. The maximum intensity of a spherical object ’s gravitational field is a function both of the amount of matter it contains and of its volume. Scientists think that such a black hole may help to support the theory that a black hole exists in the center of the Milky Way galaxy. In 2005, a black hole was discovered to be traveling at twice the escape velocity of the galaxy as it exited the Milky Way. Scientists believe that its discovery helps to confirm that gigantic black holes were created early in the formation of the universe. A black hole was discovered in June of 2004. In 2004, astronomers, while searching quasars, found over 30 possible black holes. Bodies known as black holes produce such gravitational fields. A sufficiently intense gravitational field can prevent the escape not only of matter, but even of light.
