# How can the antiparticle of Hawking radiation fall into the black hole? [duplicate]

According to the theory, when quantum fluctuations occur near the event horizon, one is absorbed and the other is emitted as hawking radiation But in order to conserve the energy the fallen particle must've been of negative mass We know that negative mass particles move in the opposite direction of the acceleration applied to it, so how can that negative mass particle fall into the black hole in the first place?
