[10] Hawking radiation depletes a black hole's mass. Radiation Exposure Calculator: Simulates exposing a simulated human to a radiation dosage of your choice. By Ian Mallett. Hawking radiation is black body radiation that is predicted to be released by black holes, due to quantum effects near the event horizon. A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how this radiation …

The original idea belongs to Jim Wisniewski, whose page from 2006 ( link ) appears to be no longer available available again, but since it is not archived by the Wayback Machine , I think my functional clone is still useful. Hawking radiation implies that is truly the physical temperature of a black hole, not merely a quantity playing a role mathematically analogous to temperature in the laws of black mechanics. The "temperature" of a black hole is the temperature that a blackbody emitter emitting the same radiation would be. Sufficiently hot holes would also emit heavier particles.

It is named after the physicist Stephen Hawking , who provided a theoretical argument for its existence in 1974, [1] and sometimes also after Jacob Bekenstein , who predicted that black holes should have a finite, non-zero temperature and entropy . By Ian Mallett. So as the black hole evaporates, it loses mass, gets smaller, gets hotter, spits out more power and, in the last second, goes out with a bang. This calculator will calculate the properties of a black hole described by given parameters (mass, charge, angular momentum), or the mass of a black hole possessing given properties; update one of the values below, and the others will recalculate. Hawking radiation is the thermal radiation anticipated to be precipitously emitted by black holes. Hawking Radiation Seminar Talk Julius Eckhard, Max Lautsch June 19, 2015 In this talk on Hawking Radiation we will first motivate why we have to introduce the counterintuitive concept of a black hole temperature leading to radiation. HAWKING RADIATION AND BLACK HOLE THERMODYNAMICS ... (2004 September 3; additional section added 2004 December 31 ‡) Abstract An inexhaustive review of Hawking radiation and black hole thermody-namics is given, focusing especially upon some of the historical aspects as seen from the biased viewpoint of a minor player in the field on and off for the past thirty years.

A black hole is a region of spacetime from which nothing escapes. Black Hole Parameters: Calculate the properties of a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It emerges from the steady conversion of quantum vacuum fluctuations into pairs of particles, one of which escaping at infinity while the other is trapped inside the black hole horizon. black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. Hawking Radiation Calculator Easy to use; enter a value for any quantity, the other values are automatically generated. The equations are not really applicable to black holes that radiate away within years.
