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 Zeptometers
A zeptometer (zm) is one sextillionth of a meter (10⁻²¹ m), 1,000 times larger than a yoctometer but still far beyond measurable scales. This unit exists in the realm of theoretical particle physics and quantum mechanics. While no physical structures exist at this scale, zeptometers are occasionally referenced in discussions about quantum fluctuations and high-energy particle interactions at colliders like the Large Hadron Collider, where particles are probed at incredibly small distances.
