Under the influence of gravity, over time the dense central part of a galaxy will contract.
To understand this, we need to consider the nature of gravity. Gravity is a fundamental force of attraction that exists between all objects with mass or energy. In the case of a galaxy, its enormous mass creates a gravitational pull inward, causing matter to be drawn toward its center.
As matter within a galaxy is pulled toward the central region, it progressively accumulates and becomes denser. This density increases the gravitational force within the central part of the galaxy, further enhancing the gravitational contraction. As a result, over time, the dense central part of a galaxy will contract, with more and more matter converging toward its center.
It's important to note that the contraction of the dense central part of a galaxy refers to the overall structure and distribution of matter, rather than the individual objects within it. Galaxies are dynamic systems with various components, including stars, gas, dust, and dark matter, all moving under the influence of gravity. However, on a larger scale, the dense central region of the galaxy contracts due to the cumulative effect of gravitational forces.
