Unreferenced date August 2011 In computer networkingnetworking , black holes refer to places in the network where incoming internet traffic traffic is silently discarded or dropped , without informing the source that the data did not reach its intended recipient. When examining the network topology topology of the network , the black holes themselves are invisible, and can only be detected by monitoring the lost traffic hence the name. Dead addresses The most common form of blackhole is simply an IP address that specifies a host machine that is not running or an address to which no host has been assigned. Even though Internet protocol suite TCP IP provides means of communicating the delivery failure back to the sender via Internet Control Message Protocol ICMP , traffic destined for such addresses is often just dropped. Note that a dead address will be undetectable only to protocols that are both connectionless and unreliable e.g., UDP .

Refimprove date March 2009 An optical blackhole is a phenomenon in which slow light is passed through a Bose Einstein condensate that is itself spinning faster than the local speed of light within to create a vortex capable of trapping the light behind an event horizon just as a gravitational blackhole would. Unlike other blackhole analogs such as a sonic blackhole in a Bose Einstein condensate, a slow light blackhole analog is not expected to mimic the quantum mechanics quantum effects of a blackhole, and thus not emit Hawking radiation. It does, however, mimic the classical mechanics classical properties of a gravitational blackhole, making it potentially useful in studying other properties of black holes. ref W.G. Unruh and R.

A charged blackhole is a blackhole that possesses electric charge . Since the electromagnetic repulsion in compressing an electrically charged mass is dramatically greater than the gravitational attraction by about 40 orders of magnitude , it is not expected that black holes with a significant electric charge will be formed in nature. A charged blackhole is one of three possible types of black holes that could exist in the theory of gravitation called general relativity . Black holes can be characterized by three no hair theorem and only three quantities, its mass M called a Schwarzschild blackhole if it has no angular momentum and no electric charge , angular momentum J called a Kerr blackhole if it has no charge , and electric charge Q charged blackhole or Reissner Nordstr m blackhole if the angular momentum is zero or a Kerr Newman blackhole if it has both angular momentum and electric charge . A special, mathematically oriented article describes the Reissner Nordstr m metric for a charged, non rotating blackhole. The solutions of Einstein s field equation for the gravitational field of an electrically charged point mass with zero angular momentum in empty space was obtained in 1918 by Hans Reissner and Gunnar Nordstr m , not long after Karl Schwarzschild found the Schwarzschild metric as a solution for a point mass without electric charge and angular momentum.

A blackhole bomb is the name given to a physical effect utilizing how a bosonic field impinging on a rotating blackhole can be amplified through superradiant scattering . An additional condition which must be met is that the field must have a rest mass different than zero. The scattered wave will then be reflected back and forth between the mass term and the blackhole becoming amplified on each reflection. The growth of the field is asserted to be exponential and unstable. The mechanism by which the blackhole bomb functions is called superradiant instability .
