comment Is there a “present state” of distant stars if simultaneity is relative?
Let's say there is a clock on the distant star that we can read using a telescope. Then by taking into account the time light was on its way, we set up a clock on Earth and be happy that now have a clock which shows what is shown now on the distant clock. Then some travelling guy in space will just say we are totally wrong, the two clocks do not go synchronized. This is quite counter-intuitive...
