论文摘要
我们描述了一种对一类暗能流体的同质和各向同性宇宙学的一般相对论的不确定性案例。宇宙学通过状态变量方程进行了参数化，其中一个实例提供了与诺顿的机械圆顶相同的解决方案。我们的示例超出了以前研究的案例，因为不确定性在于时空本身的进化：大爆炸的发作是不确定的。我们进一步表明，如果将动态视为相关性，就可以解决不确定性。
We describe a case of indeterminacy in general relativity for homogeneous and isotropic cosmologies for a class of dark energy fluids. The cosmologies are parametrized by an equation of state variable, with one instance giving the same solution as Norton's mechanical dome. Our example goes beyond previously studied cases in that indeterminacy lies in the evolution of spacetime itself: the onset of the Big Bang is indeterminate. We show further that the indeterminacy is resolved if the dynamics is viewed relationally.
