During Creation week, on Day 4, God began to fill the world he had formed on Days 1 to 3. The first act of filling was to provide government of the time and seasons. Leaders and political powers are represented throughout the Bible in the same way. They are ruling lights that oversee the lives of men. The fall of a political power is often described in apocalyptic imagery that mentions stars falling from heaven, sun darkening etc (Gen 37:9-11, Isa 13:9-13, Matt 24:29).
When this type of language and imagery is used in the New Testament there is no reason to expect a different intent. Unfortunately that hasn’t stopped a few ‘Chicken Little’s’ from getting all excited making sci-fi type doomsday predictions. What makes for entertaining escapism at the movies or bedtime stories doesn’t create good theology :(
