In physics, the Planck time (tP) 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.
I know. I wasn't saying you did lol. When I saw it I was like man this guy really knows his physics. I wanted to know more so I Googled it and then everything I thought I knew about everything was a lie.
I am also one of those people that are fascinated by this sort of thing.
