宇宙轮或时间之箭：引力的经典与量子观点
Cosmological wheel or the arrow of time: A classical versus quantum perspective of gravity
摘要：
它表明，宇宙中的结构可以解释为显示一个封闭的时间轮，而不是一个直箭头。对$f(R)$引力模型的分析表明，由于局域观测，在任何给定时空点上的一个小弧总是表示一个从过去到未来的时间箭头，尽管在量子尺度上它不是线性流而是一个闭环，这一事实可以通过未来的观测来检验。
英文摘要：
It is shown that the structures in the universe can be interpreted to show a closed wheel of time, rather than a straight arrow. An analysis in $f(R)$ gravity model has been carried out to show that due to local observations a small arc at any given spacetime point would invariably indicate an arrow of time from past to future, though on a quantum scale it is not a linear flow but a closed loop, a fact that can be examined through future observations.
