If everything has a center, where is the center of the universe?
Think about it—atoms have a center, called the nucleus, where most of their mass is concentrated. Our solar system has a center too, with all the planets orbiting the Sun. Even the Milky Way galaxy has a center, a massive black hole pulling everything around it. So, if atoms, solar systems, and galaxies all have centers, wouldn’t the universe have one too?
But here’s where it gets strange: scientists say the universe doesn’t have a single center. Instead, every point is moving away from every other point as space itself expands. It’s like blowing up a balloon where every dot on the surface gets farther apart, but there’s no single “middle.”
But what if we’ve got it all wrong? What if our galaxy—and maybe all galaxies—are actually rotating around something so massive and strange that we can’t even detect it yet? Could it be that we feel like the universe is expanding because of this cosmic motion?
So, does that mean the universe is infinite, or is there something we’re missing? What if there is a hidden center we haven’t discovered yet?
What do you think—does the universe have a center, or is it truly centerless? Let me know in the comments!
