What is Fathom ?

A Fathom is a unit of length used primarily in nautical and maritime contexts to measure the depth of water. It is defined as 6 feet or 1.8288 meters. The word "fathom" originates from Old English and means "to embrace" or "to encompass," reflecting its use in early navigation and fishing.

In practical terms, a fathom is roughly the span of an outstretched adult's arms from fingertip to fingertip. Sailors and fishermen traditionally used a weighted line marked at intervals of one fathom to measure water depth, ensuring safe passage for ships and navigation in shallow waters.

Today, while other units such as meters or feet are more commonly used for precise measurements, the fathom remains relevant in maritime industries for depth sounding and underwater activities. It's also occasionally used metaphorically to describe understanding or exploring something deeply, harkening back to its historical maritime roots.


What is Light year ?

A Light year is a unit of distance used in astronomy to measure vast distances across the universe. It represents the distance that light travels in one year through the vacuum of space, at a speed of approximately 299,792 kilometers per second (about 186,282 miles per second).

To put it into perspective, one light year is equivalent to about 9.46 trillion kilometers (or about 5.88 trillion miles). This unit is incredibly useful for describing distances between stars, galaxies, and other celestial objects that are beyond our solar system.

In simpler terms, when we say a star is located 10 light years away, it means that the light we see from that star today actually started its journey 10 years ago. Light years help astronomers understand the immense scale of the universe and how long it takes for light, the fastest known thing, to travel across these vast cosmic distances.

Understanding light years is essential for studying the universe's structure, its evolution over time, and our place within it. It allows scientists to explore and interpret the observations made by telescopes and spacecraft as they probe deeper into the mysteries of outer space.
