Yes, we can say that gravity plays a crucial role in maintaining the structure of the cosmos and influences its evolution. Here's a more detailed explanation:
1. **Gravity Balance and Maintenance of the Cosmos**:
- Gravity is the fundamental force that governs the motion of celestial objects, such as planets, stars, galaxies, and clusters of galaxies.
- The balance of gravitational forces among these objects maintains the large-scale structure of the universe. For example, the orbit of planets around stars and stars within galaxies are determined by gravitational interactions.
2. **Disturbance and Evolution**:
- The evolution of the cosmos is driven by processes that disturb this gravitational balance. For instance, the formation of stars and galaxies, the merging of galaxies, and the influence of dark matter and dark energy all contribute to changes in the gravitational landscape.
- Events like supernovae, black hole mergers, and galactic collisions can significantly disturb gravitational balance, leading to the formation of new structures and the redistribution of matter and energy.
Overall, while gravity is the primary force maintaining the structure of the cosmos, the various disturbances and interactions within the gravitational field drive its ongoing evolution.
