from THE NEW SPACETIME AND BEYOND H.D.Zeh in The Direction of Time (Springer-Verlag 1992) "...quantum correlations [of Rindler particles] ... emphasiszes the nonlocality of a relativistic Minkowski vacuum... the physical temperature is acceleration/2pi ... the discounted [nonlocal]quantum correlations with the other [far away space-like separated] half-space lead to the pseudo ensemble of states reprsenting a heat bath [i.e., the Hawking radiation and the Unruh temperature of an accelerating non-inertial particle detector are caused by faster than light connections between space-like separated virtual Rindler particles in the vacuum - JS] ..the measurement time dt is at least (accelerationxRindler frequencey)^-1 "in ordewr to mimic the presence of a horizon" p.126 "The important global difference between an accelerated observer in flat spacetime and one who is at rest at some [fixed] distance from the black hole (although both are equivalently non- inertial) is the fact .. that in the first case the total future light cone will asymptotically hit the horizon, while in the second case only a certain part of it will (depending on the distance from the horizon). Similarly, only a smaller part of the second observer's (past) celestial sphere lies in the vicinity of the horizon from which the Hawking radiation originates. This essentially modifies the Sommerfeld condition which determines the 'real' universal quantum state ... and therefore the probabilities of excitation of a counter. Only in the immediate vicinity of the horizon .. can the freely falling observer be equivalent to the inertial observer in flat spacetime, and therefore notice no radiation at all. While the Unruh radiation [detected by accelerating detector in flat spacetime] is isotropic anf T [time reversal] symmetric, the Hawking radiation [from surface of black hole in highly curved spacetime] specifies a direction in space (towards the black hole) as well as in time by its non-vanishing enegy flux." p.126 At the horizon or surface of the black hole the Unruh radiation of the freely falling observer destructively interfers with the Hawking radiation. p.126 "although the concept of the vacuum is observer-dependent, the global quantum state can be considered as 'real' (observer-independent)." According to this criterion of reality space by itself, time by itself, energy by itself, momentum by itself, electric field by itself, magnetic field by itself are not 'real' since they depend upon the observer's motion relative to sources of the fields. What is 'real' is the set of compatible invariants of the group (or semigroup or category-functor beyond group?) of frame transformations. Quantum mechanics includes frames beyond the spacetime metric in the fiber space in which a frame transform is a cahnge in what Bohr called "the total experimental arrangement" - the quantum frame transformations are nonlocal. Pontius Pilate asked "What is truth?" a precognition in mystical Gnosticism of the quantum mechanics "What is real?" - JS. "a real Rindler vacuum could be produced by a uniformly accelerating [non-inertial] mirror.... it would... drag the inertial frames if it were an ideal 'graviton' mirror ... A static [non-inertial] mirror leads to the removal of an infinite number of [vacuum] field modes [harmonic oscillators in field space not physical space-JS]... this correspnds to a (non-additive) infinite mass-renormalization, while the variation of the distance between a pair of mirrors gives rise to the finite Casimir effect...." p126 Zeh says p.127 that the virtual production of mini-black holes [Hawking's 'baby universes'] does not give a diection to time's arrow of our intuitive causality. Sid Coleman of Harvard says it does give present epoch zero cosmological constant - not the case in inflation where anti-gravity cosmological constant inflates the universe allegedly -JS "For the Unruh radiation, the energy required for the excitation of the detector is drawn from the acceeleration mechanism [e.g. Star Ship engines will have to increase their power or ship will slow down -JS] , for the Hawking radiation from the mass of the black hole. Since the presence of the thermal radiation depends upon the inertial state of the observer, the black holes loss of mass must also be observer-dependent [hence not 'real'! - JS] To quote Hawking 91976): 'If spacetime is quantized, one has to abandon the idea of a metric which is independent of the observer ... The reason is that to determine where one is in spacetime one has to 'measure' the metric,.and this act of measurement places one in one of the different branches of the wave function in the Everett-Wheeler [many worlds] interpretation.' The GOD(D) Drive of the most advanced Star Ships uses this psycho-geometric mode of propulsion - requiring an Omega class bionic man at the helm...
