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 Parsecs
A parsec (pc) is approximately 3.26 light years or 30.86 trillion kilometers, defined as the distance at which one astronomical unit subtends an angle of one arcsecond. Despite being less familiar than light years, parsecs are preferred by professional astronomers because they relate directly to stellar parallax measurements - the apparent shift in a star's position as Earth orbits the Sun. Most nearby stars are within a few dozen parsecs, our galaxy is about 30,000 parsecs across, and distant galaxies are measured in millions of parsecs (megaparsecs).
