The shortest unit of distance used in science is a Planck length, equivalent to 1.6x10^(-35)m.
If we enlarge the Planck Length to 1m, the diameter of an Electron particle will be 11 times larger than the diameter of the Milky Way🌌.
The largest unit of distance measurement is a parsec, equivalent to 3.26 light years.
