Turn slowly around in a circle, say in ten seconds.
The Andromeda Galaxy is about 2 to 3 million light
years away. In a coordinate frame that rotated with
you, the galaxy and all the light in it moved about
15 million light years in ten seconds.
You can get a similar result using linear acceleration
but the rotating frame is an extreme and obvious
example.
