How does hawking radiation work
WebJul 6, 2024 · As the universe expands faster, the event horizon becomes smaller. The smaller a region of space is, the bigger its surface is relative to the space it contains. So the smaller the event horizon gets, the less hawking radiation is emitted, but also the more “dense” the hawking radiation inside the event horizon gets. WebHow does Hawking Radiation REALLY work?

WebHow does Hawking radiation work? There should be an equal probability of matter particle and antimatter particle falling in the black hole, so, technically it shouldn't work. So how does it work? Comments sorted by Best Top New Controversial Q&A Add a Comment . Hawking radiation is theoretical black body radiation that is theorized to be released outside a black hole's event horizon because of relativistic quantum effects. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974. Hawking radiation is a purely kinematic … See more Black holes are astrophysical objects of interest primarily because of their compact size and immense gravitational attraction. They were first predicted by Einstein's 1915 theory of general relativity, before astrophysical … See more When particles escape, the black hole loses a small amount of its energy and therefore some of its mass (mass and energy are related by Einstein's equation E = mc ). Consequently, an evaporating black hole will have a finite lifespan. By dimensional analysis, … See more Astronomical search In June 2008, NASA launched the Fermi space telescope, which is searching for the terminal gamma-ray flashes expected from evaporating See more Hawking's discovery followed a visit to Moscow in 1973, where Soviet scientists Yakov Zel'dovich and Alexei Starobinsky convinced him that rotating black holes ought to create and … See more Hawking radiation is dependent on the Unruh effect and the equivalence principle applied to black-hole horizons. Close to the event horizon of a black hole, a local observer must accelerate to keep from falling in. An accelerating observer sees a thermal bath of … See more Trans-Planckian problem The trans-Planckian problem is the issue that Hawking's original calculation includes quantum particles where the wavelength becomes … See more • Black hole thermodynamics • Black hole starship • Blandford–Znajek process and Penrose process, other extractions of black-hole energy See more
WebThe black hole is nothing but gravity, intense enough to persist itself. The p / anti-p pairs are brought into existence the same way that any extremely intense field can generate particles: when you have plenty of energy, particles can pop out of it. E.g. electromagnetic radiation could do it too. – Florin Andrei. WebApr 11, 2024 · Let’s look at the essential condition for Hawking radiation in these methods. The main point to have Hawking radiation is to have geometric optic approximation or WKB approximation for and Hawking radiation near the Horizon. For Schwartzhild black hole this condition is satisfied near the apparent or event horizon \(R_s=2GM/c^2\).
