Description
While from a classical perspective we think of vacuum as empty space, it is filled by virtual particles from a quantum perspective. In flat spacetimes, these virtual particles arise in pairs, exist for a short amount of time, and then re-annihilate. As a result, no real particles are created.
In this talk, we show that real particles are created in curved spacetimes. This is because gravitational forces suppress the probability for re-annihilation, independent of the presence of event horizons. We investigate this particle production effect for the spacetime of a static, spherically symmetric Schwarzschild black hole and compare its predictions with those from Hawking radiation.
