Our Universe is expanding. No matter what galaxy you’re in, all the other galaxies are moving away from you. Well, if you’re curious, point your telescope far enough away; you’ll find that everywhere in the universe is moving away from everywhere else. You know the universe is expanding, but do you know the acceleration of its expansion? Watch it explained in the video.
