Jack McDevitt: The Engines of God series. Starts with Engines of God:
From Wikipedia:
With The Engines of God (1994), McDevitt introduced the idea of a universe that was once teeming with intelligent life, but contains only their abandoned artifacts by the time humans arrive on the scene. Although it was initially written as a standalone novel,[citation needed] the main character of The Engines of God, pilot Priscilla Hutchins, has since appeared in five more books, Deepsix (2001), Chindi (2002), Omega (2003), Odyssey (2006), and Cauldron (2007). The mystery surrounding the destructive "Omega Clouds" (which are introduced in The Engines of God) is left unexplored until Omega.[1]
I am looking for the title of a book. It is set in the future with the pending destruction of all technology advanced civilizations. There are different story threads where each learns of the pending destruction. The one that was different was a model city left on a planet as a warning.
