When two identical spiral galaxies with equal and opposite momenta merge, their gravitational pull causes them to collide and eventually merge into one larger galaxy. The resulting galaxy will have a different shape and structure compared to the original galaxies.
The equal and opposite momenta of the two galaxies cancel each other out, resulting in a slower collision and a more gradual merging process. This also helps to prevent any chaotic disruptions to the structure of the galaxies.
Galaxy mergers are a common occurrence in the universe. It is estimated that our own Milky Way galaxy has undergone multiple mergers in its history. These mergers play a crucial role in the evolution of galaxies.
The outcome of a galaxy merger is determined by various factors such as the mass and shape of the merging galaxies, the angle of collision, and the presence of other nearby galaxies that may disrupt the merging process.
Yes, the merging of galaxies can have a significant impact on their surrounding environment. The merging process can trigger the formation of new stars and alter the distribution of gas and dust in the galaxies, which in turn can affect the formation of new planets and other celestial bodies.
