. "t\u209A" . . . "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."^^ . "https://en.wikipedia.org/wiki/Planck_units"^^ . "5.39124e-49"^^ . . "\\(t_P\\)"^^ . . "Planck Time"@en .
