Stephen Hawking Formula For Black Hole

What are black holes. A short animated explanation of black holes from the world s most famous physicist and radio 4 s reith lecturer professor stephen hawking. But at the time of hawking s birth in 1942 black holes were little more than a mathematical quirk a prediction of albert einstein s 1916 theory of general relativity.

Hawking radiation is black body radiation that is predicted to be released by black holes due to quantum effects near the black hole event horizon it is named after the theoretical physicist stephen hawking who provided a theoretical argument for its existence in 1974.

Stephen hawking formula for black hole. Starting from theorems proved by stephen hawking jacob bekenstein conjectured that the black hole entropy was proportional to the area of its event horizon divided by the planck area. The term black hole. Black hole created in a lab confirms the late physicist s predictions on radiation scientists say.

In 1973 bekenstein suggested π ln 2 8 0 2722 displaystyle pi ln 2 8 approx 0 2722 as the constant of proportionality asserting that if. Researchers say they have confirmed the existence of hawking radiation. The formula is the centerpiece of our understanding of black holes and a crowning achievement for hawking who worked on it with his colleague jacob bekenstein.

Hawking radiation reduces the mass and rotational energy of black holes and is therefore also known as black hole evaporation. The larger the black hole the less accurately the position of a particle in it is defined so the more precisely the speed is defined and the less chance there is that it will be more than the speed of light. A black hole of the mass of the sun would leak particles at such a slow rate it would be impossible to detect.

Stephen hawking presented his theory on august 25 2015 at the hawking radiation conference which was co hosted by the theoretical physics institute nordita and the university of north. 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 would be changed. Created by aardman studios.

Stephen hawking was right. Hawking lucasian professor of mathematics at cambridge university achieved international fame with the 1975 theory that pioneered black hole science and was later popularized in his book a brief.
