Opposite Arrows of Time Can Reconcile Relativity and Nonlocality
We present a quantum model for the motion of N point particles, implying nonlocal (i.e., superluminal) influences of external fields on the trajectories, that is nonetheless fully relativistic. In contrast to other models that have been proposed, this one involves no additional space-time structure as would be provided by a (possibly dynamical) foliation of space-time. This is achieved through ...
متن کاملOpposite Thermodynamic Arrows of Time
The possibility of simultaneous opposite running thermodynamic arrows of time has been raised on several occasions, for didactic purposes [1], for general interest [2], and to confound by “obvious” counterexample [2]. A difficulty in these considerations is the absence of a welldefined framework. For example, one might argue against opposing arrows as follows. Let the systems be A and B. An obs...
متن کاملRelativity and Nonlocality
The general theory of relativity is in good agreement with experimental data available at present; however, a microphysical understanding of gravity is still missing. There are many different attempts to reconcile general relativity with the quantum theory. The approach adopted here seeks to examine the physical foundations of general relativity in the light of the principles of quantum physics...
متن کاملRemarks on the Compatibility of Opposite Arrows of Time II
In a series of papers [1, 2, 3], Lawrence Schulman presented examples which demonstrate the compatibility of opposite arrows of time in various situations. In a previous letter to this journal [4] I questioned some of them for not being realistic in spite of being logically correct. Schulman replied [5] to these objections in a letter directly succeeding my one. I am here trying to clarify some...
متن کاملRemarks on the Compatibility of Opposite Arrows of Time
I argue that opposite arrows of time, while being logically possible, cannot realistically be assumed to exist during one and the same epoch of this universe.
