时间总是随着重力的增加而变慢吗?
Does time always slow down as gravity increases?
摘要:
我们考虑静止的观察者之间的引力时间膨胀和目前的例子,这与“随着引力的增加,时间变慢”的说法相矛盾。我们进一步表明,这种说法不可能是真的,在一般情况下,如果引力的强度被定义在一个观察者独立的方式。我们还提供了一个教学介绍引力时间膨胀,并讨论这一现象的方面,这往往是在广义相对论的教科书省略。
英文摘要:
We consider gravitational time dilation between stationary observers and present examples, which contradict the statement that "time slows down as gravity increases". We show furthermore that this statement cannot be true in general, if strength of gravity is defined in an observer independent manner. We provide also a pedagogical introduction to gravitational time dilation, and discuss aspects of this phenomenon, which are often omitted in textbooks on general relativity.
