If galaxies are constantly merging and transforming, what does this imply about the nature of 'stability' or 'permanence' in the universe?

The dynamic nature of galaxies challenges any notion of cosmic stasis. What appears stable on human timescales is, on cosmic scales, in constant flux. Stars are born and die, galaxies collide and merge, black holes grow and exert influence. This insight can encourage a more dynamic worldview, recognizing change as a fundamental and creative force, not just an end. It suggests that even the most massive structures are transient, participating in an ongoing cosmic dance.
