Calculating Hawking radiation at the event horizon of a black hole

WebApr 16, 2024 · Hawking radiation is actually the result of how gravity affects space-time, as described by General Relativity. The quantum fields in empty space obey Heisenberg’s uncertainty principle, which means there is a limit to the certainty with which we can know their energy, or the time at which a specific energy can be assigned to them. WebThe Hawking Radiation shows that the laws of black hole thermodynamics have a complete physical meaning. Emission process. A black hole emits thermal radiation at a … 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 effect that is generic to Lorentzian geometries containing event horizons or local apparent horizons. the scottish terrier society
