Time just got much shorter....
Planck time is the smallest meaningful unit of time in physics, representing the time it would take for light to travel one Planck length in a vacuum. It’s named after the physicist Max Planck, who developed the concept as part of a set of natural units in quantum mechanics.
Mathematically, Planck time ( t_P ) is defined as:
t_P = \sqrt{\frac{\hbar G}{c^5}}
where:
• \hbar is the reduced Planck constant,
• G is the gravitational constant, and
• c is the speed of light in a vacuum.
The value of Planck time is approximately 5.39 \times 10^{-44} seconds.
