1e-43 s

To help compare different orders of magnitudes this page lists times between 10^-43 s and 10^-42 s.

• 10^-43 s -- [Planck time]?, the time it would take a photon travelling at the speed of light to across a distance equal to the [Planck length]?. No smaller division of time has any meaning.

• [Longer times]?
