Who proposed that black holes can evaporate?
Stephen Hawking was the first scientist to suggest that the black holes evaporate. His theory of Black Holes emitting radiation, also termed as Hawking Radiation.Hawking radiation is black body radiation that is predicted to be emitted by black holes, due to quantum effects near the event horizon. It is named after the physicist Stephen Hawking, who provided a theoretical argument for its existence in 1974, and sometimes also after the physicist Jacob Bekenstein who predicted that black holes should have a finite, non-zero temperature and entropy. Hawking's work followed his visit to Moscow in 1973 where Soviet scientists Yakov Zeldovich and Alexei Starobinsky showed him that according to the quantum mechanical uncertainty principle,rotating black holes should create and emit particles. Hawking radiation reduces the mass and the energy of the black hole and is therefore also known as black hole evaporation. Because of this, black holes that lose more mass than they gain through other means are expected to shrink and ultimately vanish. Micro black holes (MBHs) are predicted to be larger net emitters of radiation than larger black holes and should shrink and dissipate faster.In Hawking Radiation, Virtual particle pairs are constantly being created near the horizon of the black hole, as they are everywhere. Normally, they are created as a particle-antiparticle pair and they quickly annihilate each other. But near the horizon of a black hole, it's possible for one to fall in before the annihilation can happen, in which case the other one escapes as Hawking radiation.
How did Stephen Hawking discover that black holes emit heat?
He stated that Black Holes emit heat because they are nothing more than collapsed stars that suck in particles and then they themselves are destroyed. After doing so the object that was sucked into the black hole is sent back into its own universe, instead of being transported to a parallel universe. Since energy is needed for these processes it is necessary for light and Light=Heat. It all has to do with light wavelength and the conversation of matter.
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.
When and where did stephan hawking make his discovery?
Stephen Hawking made significant contributions to theoretical physics and cosmology throughout his career, particularly in the 1970s. One of his most notable discoveries, regarding black hole radiation (now known as Hawking radiation), emerged from his work during the early 1970s while he was at the University of Cambridge. His findings were published in a series of papers starting in 1974, reshaping our understanding of black holes and their properties.
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.

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.
