Who proposed that black holes can evaporate?
Stephen Hawking proposed the theory that black holes can evaporate through a process now known as Hawking radiation. This phenomenon suggests that black holes can emit radiation and gradually lose mass over time until they eventually disappear.
How did Stephen Hawking discover that black holes emit heat?
Stephen Hawking proposed in 1974 that black holes emit radiation, now known as Hawking radiation, due to quantum effects near the event horizon. This radiation causes black holes to lose mass and energy over time. His theory combined quantum mechanics and general relativity to explain the behavior of black holes.
How long did it take Stephen hawking to find out about black holes?
Stephen Hawking began studying black holes while writing his doctoral thesis in the early 1960s. It wasn't until 1974 that he made groundbreaking contributions to the field with his discovery of Hawking radiation, which revolutionized our understanding of black holes.
How do scientists know something about black holes?
As you might imagine, it's very difficult to observe black holes. For a very long time, we weren't even sure we _could_. As it happens, there are a few aspects of black holes that make it possible to detect their presence, but their nature prevents us from directly observing what occurs inside the singularity. Since we can't observe them, the main way scientists understand black holes is through mathematics. Karl Schwartzchild first predicted them as one solution to the Einstein field equations at the heart of Einstein's General Theory of Relativity, back in 1915. Later scientists found additional solutions that also pointed toward the existence of black holes, and helped refine our prediction of the behavior of space-time near them. Quantum field theory has been used, as well. One of the best known cases is Dr. Stephen Hawking's prediction, in 1974, that black holes should act like a black body, radiating energy in an amount inversely proportional to the surface gravity of the black hole. The amount of 'Hawking radiation' produced by a mass the size of a star ends up being very small. A black hole with the mass of our sun would emit only 9 × 10−29 watts.

Black As He's Painted was created in 1974.

What is the purpose of the Hawking radiation calculator and how can it be used to study black hole evaporation?
The purpose of the Hawking radiation calculator is to estimate the rate at which black holes emit radiation, known as Hawking radiation. This calculator can be used to study the process of black hole evaporation by providing insights into how black holes lose mass and energy over time through the emission of radiation. Scientists can use the calculator to analyze the effects of various factors, such as the mass and size of the black hole, on the evaporation process.

Do black holes emit radiation, and if so, what are the implications of this phenomenon on our understanding of the universe?
Yes, black holes emit radiation, known as Hawking radiation. This phenomenon suggests that black holes can slowly lose mass and eventually evaporate. This challenges previous ideas about black holes being completely "black" and has implications for our understanding of the nature of space, time, and the universe as a whole.
