Planck Time
Planck time, abbreviated as \(t_p\), is a fundamental unit in the system of Planck units. It is based on the speed of light, the energies needed to smash particles in the universe at a time equal to the Planck length and universal gravitational constant divided by the speed of light. It is a useful unit in theoretical physics.
