Just how big is the universe?

This big. And that's just the VISIBLE universe. These maps only show the distances to galaxies, clusters, nebulas and the sort that are relatively close to the Earth. Most galaxies are so far away that their distances cannot be accurately calculated and aren't included. Use the zoom-in buttons to see how the Solar System compares to the immense vastness of the universe. Just consider the Earth's place in all of this: a infinitesimal speck amonst a plethora of other infinitesimal specks. The sun is one star in an estimated 30 billion trillion (3x10²², or 30000000000000000000000). I challenge you to find a thought more humbling than that.
