Examples

  • We certainly do not have observations; the Planck length, expected as their size, is just too tiny.

  • So the answer to what is half of Planck time is There isn't.

  • The Planck length, the Planck mass, the Planck length.

  • And it's also a Planck length square.

  • Those are the things we used when we looked at the Planck units, like the Planck length.

  • Planck length versus Planck time?

  • The Planck length and the Planck mass define the Planck density.

  • And here's this Planck length squared again.

  • In this way, the value of Planck's constant is essential to the global, physical character of the universe.

  • The associated time scale which characterizes change at this length is 10^-43 seconds, the Planck time.

Etymology

Planck in terms like 'Planck length' comes from Max Planck. He found an important number in physics, so scientists use his name for the basic units that describe the very smallest parts of nature.
