The energy to create a virtual particle-antiparticle pair lasts only a short time and does not have to be accounted for in the usual conservation of energy balance.However,if the virtual particles are transformed into real particles,their energy must come from some physical source.In the case of the Hawking process,what is the source of this energy?
