About Attometers
An attometer (am) is one quintillionth of a meter (10⁻¹⁸ m), smaller than atomic nuclei but larger than the realm of pure theory. This scale represents the size of individual quarks within protons and neutrons, though quarks are considered point particles with no measurable size. Attometers are used in high-energy physics experiments that probe the internal structure of protons through deep inelastic scattering, revealing the distribution of quarks and gluons within.
About Femtometers
A femtometer (fm) is an incredibly tiny unit equal to one quadrillionth of a meter (10⁻¹⁵ m). To put this in perspective, if an atom were the size of a football field, a femtometer would be the size of a marble. This unit is primarily used in nuclear physics to measure the size of atomic nuclei, protons, and neutrons. The proton, for example, has a diameter of about 1.7 femtometers.
