How long does light take to travel between the Andromeda Galaxy and the Milky Way?
Answer
2.5 million years
Light travels at a constant speed of approximately 300,000 kilometers per second. Even at this extreme velocity, the sheer vastness of space between the Andromeda Galaxy and the Milky Way results in a transit time of roughly 2.5 million years for light to travel from one to the other, illustrating the immense scale of the Local Group.
