You occupy a very special place in the universe. Or, perhaps more accurately, a very special size.
Things in this universe can be mind-bogglingly large, like galactic clusters, or unimaginably small, like quarks. You — all of us — inhabit a peculiar place in this grand scale of sizes: smack-dab in the middle. The fundamental unit of life, the living cell, sits at the geometric mean between the biggest things in the universe and the teensiest.
From this privileged position in the middle, how well do you know all things great and small?
This quiz will test your knowledge, and the answers will show you where you sit on our new Quantum to Cosmos interactive scale of the universe.
