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 Angstroms
An angstrom (Å) is equal to 0.1 nanometers or 10⁻¹⁰ meters, named after Swedish physicist Anders Jonas Ångström. While not an official SI unit, it remains widely used in chemistry, solid-state physics, and crystallography to express atomic distances and wavelengths. A typical atom has a diameter of 1-3 angstroms, and the spacing between atoms in crystals is commonly measured in angstroms. X-ray crystallographers use angstroms to describe molecular structures with atomic precision.
