Watch the real scale comparison as objects grow from just 1 femtometer all the way to approximately 93 billion light-years across. This 3D animated comparison includes some of the largest and smallest things in the known universe, including planets, giant stars, supermassive black holes, the Milky Way, Andromeda, enormous cosmic structures, and the observable universe. How small are we compared to the universe? How big are the largest stars and black holes? And what does the scale of the universe actually look like?
