No, the collision between the Andromeda Galaxy and the Milky Way is not expected to occur within our lifetime. The collision, often referred to as the "Andromeda-Milky Way merger" or "Andromeda-Milky Way collision," is predicted to take place in the distant future, approximately 4 billion years from now.
Both the Andromeda Galaxy and the Milky Way are large spiral galaxies within the Local Group, a collection of galaxies that also includes several smaller galaxies. Currently, Andromeda is located about 2.537 million light-years away from the Milky Way. Over the course of billions of years, the gravitational interactions between these galaxies will cause them to gradually approach each other.
As the galaxies continue to move closer, their mutual gravitational attraction will eventually lead to a collision and subsequent merger. However, the timescale for this event is incredibly long compared to the human lifespan. It is estimated that the actual merger process will take several hundred million years to complete.
While the collision between Andromeda and the Milky Way is a fascinating cosmic event, it is not something we can witness within our lifetime. It serves as a reminder of the vast timescales and dynamic nature of the universe.
