Milky Way galaxy might not collide with Andromeda after all

The Milky Way's fate has been predicted for centuries as doomed to collide with Andromeda in about 5 billion years, merging into a larger galaxy. However, new research using 100,000 simulations suggests this outcome is far from certain—a 50% chance of collision within the next 10 billion years. The study highlights that our understanding of galaxy interactions remains incomplete due to factors like dynamical friction and dark matter influences in the Local Group. This revelation underscores the complexity of cosmic evolution and the need for continued research into these mysterious forces.
