What is a Exameters (Em)
Definition: An exameter (Em) is a unit of length equal to 10^18 meters. It is used primarily in theoretical physics and astronomy for describing vast cosmic distances.
History: As the metric system expanded, large-scale units like the exameter were introduced to accommodate astronomical and scientific measurements requiring extremely large distances.
Current Use: Exameters are rarely used in everyday applications but appear in astrophysics when discussing interstellar distances, black hole measurements, and the size of cosmic structures.
What is a Light Years (ly)
Definition: A light-year (ly) is the distance light travels in one Julian year (365.25 days), approximately 9.461 trillion kilometers or 5.878 trillion miles. It is used for measuring astronomical distances.
History: The term 'light-year' was first introduced in the 19th century to help astronomers express cosmic distances. It replaced astronomical units that were cumbersome for measuring vast space distances.
Current Use: Light-years are used in astronomy to describe distances between stars, galaxies, and other celestial objects. It is crucial for understanding the scale of the universe and cosmic events.
