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 Picometers
A picometer (pm) is one trillionth of a meter (10⁻¹² m), making it 1,000 times larger than a femtometer but still unimaginably small. This unit is crucial in atomic and molecular physics, as it represents the scale of atomic radii and chemical bonds. For example, a hydrogen atom has a radius of about 53 picometers, and the length of a typical chemical bond ranges from 100 to 200 picometers. X-ray wavelengths also fall within this range.
