Recently, physicists trying to meld gravity and quantum theory, and so explain the nature of space and time, have begun to revisit this old question.
最近，物理学家试图把引力和量子理论融为一体，由此来解释空间和时间的性质，已经开始重新研究这个老问题。
In quantum theory, it's even less well defined: time doesn't even figure as something that gets measured.
而在量子理论中，时间更加无法定义：时间甚至不具有可以测量得到的特质。
According to quantum theory, the shortest moment of time that can exist is known as Planck time, or 0.0000000000000000000000000000000000000000001 second.
根据量子理论，能够存在的最小时间单位叫做普朗克时间，长度为0.0000000000000000000000000000000000000000001秒（一千亿亿亿亿亿分之一秒）。
Ultimately, we may have our first indication of how space-time emerges out of quantum theory.
最终，我们将第一次从量子理论中揭开时空的庐山真面目。
Quantum-gravity theory indicates that the fabric of space-time has an "atomic" geometry that is woven with one-dimensional quantum threads.
量子引力理论指出时空结构具有一个由一维量子线编织成的“原子”几何图。
They have to stitch quantum theory - our description of how very small things behave - together with relativity - the theory behind the way space, time and matter interact.
他们需要将量子力学和相对论这两大物理学理论统一起来——前者是人类对微观粒子运行的描述，而后者则适用于解释宏观的空间、时间和物质相互作用的机制。
At the same time, for intuitional analysis, we introduce semiclassical theory and Bohmian theory, they all provide intuitive explanations to the quantum interference process.
同时为了分析问题的需要，我们介绍了半经典理论和玻姆理论，他们都能为揭示量子相干过程提供直观的物理解释。
