摘要:
相对性原理最初是由伽利略提出的,它指出该原理本身的适用范围是孤立系和惯性参考系。这一原理并不主张任何物理系统总是可以孤立的,实际上,它允许存在与不可孤立的物理系统有关的现象的可能性,例如,由某种不可拖动的以太调节的现象。在Aspect实验之后,基于纠缠系统不是孤立的假设,专门提出了现实主义和局部模型。据推测,允许违反贝尔不等式的相关性是由于系统的各个部分之间的超光速信号的交换,这些信号不会产生因果悖论,因为它们的传播是由不可拖动的以太调节的。在本文中,这种模型与相对论的完美兼容性是大力提倡的。最后提出了一个标准来确定事件之间的因果排序,因为当有超光速信号时,该排序不再与标准同步引起的时间排序相关联。
英文摘要:
The principle of relativity, as originally expressed by Galileo, points out that the area of competence of the principle itself is that of isolated systems as well as inertial reference frames. The principle does not claim that it is always possible to isolate any physical system, indeed it leaves it open to the possibility of the existence of phenomena concerning non isolable physical systems, e.g. phenomena regulated by some non draggable ether. After the Aspect experiment realist and local models have been proposed specifically based on the hypothesis that entangled systems are not isolated. It is hypothesized that the correlations which allow the violation of Bell's inequality are due to exchanges of superluminal signals between the various parts of the system and those signals do not generate causal paradoxes because their propagation is regulated by a non draggable ether. In the present paper the perfect compatibility of such models with the relativity theory is strongly advocated. A criterion is finally proposed to determine the causal ordering between events since, when there are superluminal signals, that ordering can no longer be associated to the time ordering induced by the standard synchronization.
