WebTo understand how fast the expansion of space was, there are some units that you should know of. A Planck length is a unit of distance that equals roughly 1.616 times 10^-35 meters. This unit is incredibly small. To scale it, if an atom were the size of the observable universe, a Planck length would be the size of a tree. Next is Planck time.
