In Relation to us, galaxies are doing what?: Galaxies, in relation to our own, are moving away from us. This movement is not random; rather, it is part of a larger pattern called the expansion of the universe. This expansion is not like a balloon expanding into empty space; instead, it is the very fabric of space itself expanding.
As galaxies move away from us, they also move away from each other. The farther away a galaxy is, the faster it appears to be moving away. This observation led to the development of the idea of the expanding universe and the Big Bang theory, which suggests that the universe began as a single point and has been expanding ever since.
The expansion of the universe also has implications for the future. Based on current observations, galaxies will continue to move away from each other, eventually to the point where other galaxies will be so far away that they will no longer be visible from our own Milky Way galaxy.
In summary, galaxies are not just static objects in the sky; they are dynamic entities that are constantly moving away from each other as part of the overall expansion of the universe.
