论文摘要
关于物理学中不确定性的讨论集中在开放未来的可能性上,即有潜在的未来事件的可能性,其中一种事件的实现并未由当前的状况确定。但是,不确定性也会影响过去,也可以使它开放吗?我们表明,通过维护信息有限的原则,人们可能需要这种可能性。我们提供了一个玩具模型,该模型显示了过去如何从根本上不确定,同时还解释了过去的直观(和观察到的)不对称性 - 至少可以部分地记住,这是无法完全预测的。
Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs. Yet, can indeterminism affect also the past, making it open as well? We show that by upholding principles of finiteness of information one can entail such a possibility. We provide a toy model that shows how the past could be fundamentally indeterminate, while also explaining the intuitive (and observed) asymmetry between the past -- which can be remembered, at least partially -- and the future -- which is impossible to fully predict.
