Planck time


Planck time
   a unit of time equal to the time required for a photon moving at the speed of light to travel the distance of one Planck length. This is the shortest time that is meaningful in our understanding of the laws of physics, representing the scale at which time itself may become quantized (discrete) rather than continuous. The Planck time is about 1.351 x 10-43 second.
