Planck समय
Planck time (tP) is the natural समय की मात्रक in the Planck system of units, लगभग के बराबर 5.391 × 10⁻⁴⁴ seconds. It को परिभाषित किया गया है the time required for light to travel one Planck length in a vacuum and represents the scale at which quantum gravitational effects are believed to become significant. Below this timescale, current physical theories are not expected to remain valid without a theory of quantum gravity.
