About Gigaparsecs
A gigaparsec (Gpc) is one billion parsecs or 3.26 billion light years, used for measuring the largest structures in the cosmos. The observable universe has a radius of about 14.3 gigaparsecs (46 billion light years when accounting for expansion). Superclusters and cosmic filaments, the largest known structures, span hundreds of megaparsecs to gigaparsecs. The cosmic microwave background radiation originates from a distance of about 14 gigaparsecs. This unit helps cosmologists map the large-scale structure of the universe and understand its evolution since the Big Bang.
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.
