Neil deGrasse Tyson: 我认为时间测量不仅需要运动，还需要重复的事件。如果没有重复的运动，就无法连贯地测量时间。在我的参考系中，如果没有任何东西重复，时间就无法被有意义地测量。空间可以独立于时间而存在，空间并不需要时间。 Chuck Nice: 我赞同尼尔的观点，测量时间需要重复的运动。我们都处于彼此的视界范围内。

Deep Dive

Chapters
Neil deGrasse Tyson and Chuck Nice discuss whether the measurement of time necessitates motion, particularly repetitive motion. They explore the concept of sequencing events without a repeatable unit of measurement and conclude that while space can exist without time, the measurement of time requires motion.
  • Measurement of time requires repetitive motion.
  • Sequencing events is possible without a repeatable unit of measurement.
  • Space can exist without time.
