Question #03446

Sep 15, 2017

${10}^{-} 43$ seconds

Explanation:

$d = v t$

For $d$, the distance, we use the Planck Length.
For $v$, the velocity, we use the speed of light.
And we can solve for the time, $t$.

The Planck Length is about $1.6 \cdot {10}^{-} 35 m$.
The speed of light is about $2.998 \cdot {10}^{8} \frac{m}{s}$.
Light traveling at $c$, the speed of light, will travel this distance in about ${10}^{-} 43$ seconds. This is also known as the Planck Time.
