Fermilab's video: 20 Subatomic Stories: Is the Planck length really the smallest

A reasonable question of physics is if there is a smallest possible size and shortest duration and some scientists have claimed that there is and they are called the Planck length and Planck time. In this episode of Subatomic Stories, Fermilab’s Dr. Don Lincoln explains the truth of the Planck constants. It’s not what you think.
