dcterms:description

In physics, the Planck time, denoted by \(t_P\), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it. \( \\ t_P \equiv \sqrt{\frac{\hbar G}{c^5}} \approx 5.39106(32) \times 10^{-44} s\) where, \(c\) is the speed of light in a vacuum, \(\hbar\) is the reduced Planck's constant (defined as \(\hbar = \frac{h}{2 \pi}\) and \(G\) is the gravitational constant. The two digits between parentheses denote the standard error of the estimated value.
