light year [ly]

Definition

A light year is the distance that light travels in one year in a vacuum. It is approximately equal to 9.461 trillion kilometers or 5.878 trillion miles.

History/Origin

The concept of the light year was first proposed by the Danish astronomer, Ole Rømer in the 17th century. Rømer used observations of the eclipses of the moons of Jupiter to estimate the speed of light and used this to calculate the distance between the Earth and Jupiter. It was not until the 19th century that the term "light year" came into use.

Current Use

The light year is primarily used to measure distances within the universe, particularly in astronomy and astrophysics. It is used to describe the distances between stars, galaxies, and other celestial objects. It is also used to measure the size of the observable universe, which is estimated to be approximately 93 billion light years in diameter.

meter [m]

Definition:

The meter (m) is the fundamental unit of length in the International System of Units (SI).

History/Origin:

The meter was originally defined as one ten-millionth of the distance between the North Pole and the Equator along the meridian passing through Paris.

Current use:

The meter is widely used in science, engineering, and everyday life to express distances, dimensions, and sizes of physical objects.
