About Fathoms
A fathom (ftm) is equal to 6 feet or 1.8288 meters, traditionally based on the span of a man's outstretched arms. This unit has been used for centuries in maritime navigation to measure water depth and rope or cable lengths. While largely replaced by meters in modern nautical charts, fathoms remain in use by sailors and in naval traditions. The Mariana Trench, Earth's deepest point, reaches about 6,000 fathoms. The term 'to fathom' meaning 'to understand' derives from this nautical unit.
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.
