Answer:

The universe is expanding.

Explanation:

Following the theory that the universe was originated from a single heavily compressed and super hot point, and quickly expanded itself to what we see today, we can assume that the universe is still expanding.

According to the big bang theory, the remnants of that explosion still cause the planets and elements in the universe to move farther from one another, allowing the universe to continue its expansion. This expansion has become slower and slower over billion of years, and the scientific community doesn't know for sure if the expansion will go on forever, or if it will have an end.

The mountains are a natural barrier for lot of human activities, and one of those is the formation of settlements, big countries, or empires. The creation of large empires on a mountainous terrain is extremely hard and unpractical, and there's very few cases in the human history that that has been performed well. The reasons for that is that in the mountainous regions it is hard to create a network of roads, build large settlements, and also there's lack of natural resources and food, so the people had the tendency to create small settlements, or city-states in this kind of circumstances.
