哥德尔宇宙中的最佳时间旅行

Optimal time travel in the Godel universe

Jose Natario

摘要:

利用最近在arXiv:1105.5235中发展的广义相对论中的最优火箭轨道理论,我们提出了Godel宇宙中最小总积分加速度封闭类时曲线的一个候选,并给出了它的极小性的证据.这条曲线的总积分加速度低于Malament的假设值(Malament,1984),这在Manchak的工作中已经隐含了(Manchak,2011);然而,Malament的猜想似乎确实适用于周期性封闭的类时曲线。

英文摘要:

Using the theory of optimal rocket trajectories in general relativity, recently developed in arXiv:1105.5235, we present a candidate for the minimum total integrated acceleration closed timelike curve in the Godel universe, and give evidence for its minimality. The total integrated acceleration of this curve is lower than Malament's conjectured value (Malament, 1984), as was already implicit in the work of Manchak (Manchak, 2011); however, Malament's conjecture does seem to hold for periodic closed timelike curves.
