The Milky Way galaxy is not contracting; rather, it is gravitationally stable and continues to evolve through processes such as star formation and mergers with smaller galaxies. While the galaxy's outer regions may experience some changes in motion and structure, the overall dynamics are governed by gravitational forces that maintain its shape. Additionally, the Milky Way is on a collision course with the Andromeda galaxy, which will lead to a merger in about 4.5 billion years, further altering its structure rather than causing contraction.
