You were fast with the stopwatch indeed!

The fact that it's possible to pick up something that "dropped" on the floor before it gets dirty is very mind-opening. : )

Planck length is actually not the smallest but the smallest meaningful length, the distance below which the very notions of space and length cease to exist. Any attempt to investigate the possible existence of shorter distances would result in black hole production.

Thanks for sharing so many interesting facts! ^^
