Meanings
-
A natural unit of time, equivalent to the time it takes light to traverse one Planck length; it is the duration of time at which quantum gravity effects are expected to become significant.
As Dr. Feynman noted, there are still shorter scales of time and distance to go before we reach the ultimate limits imposed by quantum physics: the Planck length, 10^-33 of a centimeter, and the Planck time, 10^-43 of a second. Both are named for the German physicist Max Planck, who made the breakthrough that led to quantum mechanics.
