An introduction to black holes information and the string theory

... in the classical theory, there are no limits on how much infor- mation can be sent in an arbitrarily small time with arbitrarily small en- ergy. However in quantum mechanics, to send a single ... can be an ambiguity. The real proton propagating through space-time is not the simple struc- tureless bare proton. The interactions cause it to make virtual transitions from the bare proton...
