How fixed is all this? It would be nice if we could scroll through time.



Pretty much everything beyond our solar system is essentially fixed on a human timescale. Over 2000 years, a typical star will move about half a degree. That's the width of the moon in the sky. There are of course notable exceptions like Barnard's Star, whose movement is pretty obvious on photographs taken over several decades.

If you want to explore how space changes over time, I recommend you look into something like Celestia[0]. It allows you to simulate star movement over thousands of years, and show you how the night sky looked to the Ancient Egyptians.
