This concept can best be explained through the "balloon analogy": imagine you are a random spot on a spotted balloon, when someone inflates the balloon you'll see the spots moving away from you, so it would seem you are at the center of the expansion, furthermore the further away the spots are the faster they move away from you, this is also true for the universe: the more distant a galaxy is, the faster it moves away from us. | This concept can best be explained through the "balloon analogy": imagine you are a random spot on a spotted balloon, when someone inflates the balloon you'll see the spots moving away from you, so it would seem you are at the center of the expansion, furthermore the further away the spots are the faster they move away from you, this is also true for the universe: the more distant a galaxy is, the faster it moves away from us. |
