The fastest thing in the universe is light, and the amount of time it takes a photon (in a vacuum, absent of gravity), to transit a planck is called planck-time.

They have found a number of places, both in the night sky and in the laboratory, where the nature of space and time at the Planck scale would have indirect, but observable effects.
