Hawking radiation from a black hole?

Click For Summary
SUMMARY

Stephen Hawking's theory posits that black holes emit thermal radiation, known as Hawking radiation, due to the intense gravitational field surrounding the event horizon. This radiation does not originate from within the black hole itself but rather from the quantum effects occurring just outside the event horizon. The discussion clarifies that light cannot escape a black hole, as it cannot exceed the speed of light, and emphasizes the role of gravitational forces in this phenomenon.

PREREQUISITES
  • Understanding of black hole physics

In his theory, Stephen Hawking suggests that a black hole will give off thermal radiation. Radiation is light, so how can light escape the gravity of a black hole, especially originating from one? The only way I could see this was that if radiation were traveling beyond the speed of light, but that's not possible, right?

welcome to pf!

hi mAMBOkING! welcome to pf! :wink:

it doesn't come from the black hole …

it comes from the intense gravitational field just outside the event horizon :smile:

Yess is possible by the centrepetal forces imself d'ont you think ? no
