Step-by-step explanation:
GALAXIES IN CONSTANT MOTION
According to the Big Bang Theory, galaxies are in constant motion and are moving away from each other.
This movement is referred to as the expansion of the universe.
Galaxies are not only moving away from each other, but they are also moving at different speeds in different directions.
However, it is important to note that this motion is not due to galaxies being propelled by a force but rather the result of the overall expansion of space.
