静态观测者对哈勃定律和宇宙学红移的物理解释

A physical interpretation of Hubble's law and the cosmological redshift from the perspective of a static observer

Simen Braeck, Oystein Elgaroy

摘要:

我们推导出明确的和精确的表达式的物理速度的自由粒子与哈勃流测量的静态观察者,和由一个comoving源发出的光的频移和接收,再次由静态观察者。这些表达式清楚地表明,将红移解释为一种多普勒效应,只有在观测者和光源之间的距离完全消失时才有意义。

英文摘要:

We derive explicit and exact expressions for the physical velocity of a free particle comoving with the Hubble flow as measured by a static observer, and for the frequency shift of light emitted by a comoving source and received, again, by a static observer. The expressions make it clear that an interpretation of the redshift as a kind of Doppler effect only makes sense when the distance between the observer and the source vanishes exactly.
