SUMMARY
The discussion centers on the concept of torque in relation to a galaxy's spin, emphasizing that torque is linked to the transfer of angular momentum over time. It highlights that gravitational waves can influence the paths of distant objects and that galaxies can exert torque on one another, particularly during collisions. An example provided is a star escaping the Milky Way due to its close encounter with a black hole, illustrating the effects of galactic torque. It is concluded that a galaxy itself does not possess torque independently; rather, interactions between galaxies and their components generate torque through dynamic interactions.
