A:
- The gravitational pull of a black hole is so strong that even light cannot escape. But in the quantum mechanical model, a black hole emits radiations known as Hawking radiation.
- This happens because of pair production near the event horizon in which one particle is absorbed while the other escapes with some energy from the black hole.
- The lifetime or the time taken for a black hole to completely evaporate is given by,
Here M is the mass of the black hole and α is a constant with a value of 3.96 × 1015 kg3∙s-1.
