Planck time
noun1
Natural sciences, Physical sciences, Physics 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.2023 October 9, Dennis Overbye, “The Science Nobel Winners Were Short and Fast”, in The New York Times, archived from the original on 12 Oct 2023:
