Hawking radiation research. Future space probe approaching a black hole to capture Hawking radiation (blue glow). A black hole is formed when the core of a star collapses under its own weight,increasing the strength of its gravitational field to the point where usually nothing,not even light,can escape. Hawking radiation,however,consists of particle-antiparticle pairs formed from the quantum vacuum,with one particle falling into the black hole and the other escaping by quantum tunnelling. This mechanism allows small black holes to rapidly evaporate | |
