Because if you measured it in miles, it would add possibly beond the trillions! (whoa!)

Why is light years used as a unit of the universe?
Because the universe is so large, they need something like light to at least reach large amounts of distance.
How does these two quantities determine the speed of light?
The distance in meters covered by light in one second is considered to determine the speed of light. Speed of light is 3*108m/s. The unit of speed of light is meters per second.
How does light determine the age of object in the universe?
Look up at the sky, and its second star to the right strait on till morning!
What is the meaning of 15 Light Years?
The distance light will travel in 15 years. Or about 1.42 x 1014 kilometers.
How do distances between planets solar systems galaxies and the universe compare?
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
what is the distance of equator of our universe?
universe's equator distance is about 150,000,000,000 light years.
What is the Meaning of baby name jagdeep?
light of the universe
In astronomy and distances of the universe how much is a ly?
A light year is the distance that light can travel in a year.
Why is light years used as a unit of the universe?
Because the universe is so large, they need something like light to at least reach large amounts of distance.
Where in the Universe would you find light year?
A light year is not a physical object; rather, it is the distance light travels in a year.
What is the longest known distance in light years?
That would be the distance from one edge of the Known Universe to the other. As the Known Universe is believed to be approximately 15 billion years old, that would be 30 billion light years in diameter.
Is 13.7 billion light-years the radius of the visible universe in light travel distance?
Yes. It is 13.7 billion light-years in radius in light travel distance according to Ned Wright's Cosmology calculator.
Does man know the extent of universe?
the limits of universe are still not defined. until now whatever we know about the limits of universe is because of the light we see. if we keep on receive light from farther distance than that means universe's limits are even beyond. but if we don't receive light from farther distances than that means universe has limits. THIS IS NOT A PROFESSIONAL ANSWER.
What are facts about lightyears?
A light year is a measurement of distance, not of time. It is the distance light travels in one year. Light is used to measure distance since it is the fastest thing in the Universe. A light-year equals about 9.46053 x 1012 km (or 5.878 x 1012 miles).
Why was it necessary to definite new unit to measure distance in universe?
Because of the unwieldy large numbers that would otherwise be required.A Parsec is the distance from the Sun to Earth, and a light year is the distance that light would travel in a year.
How does these two quantities determine the speed of light?
The distance in meters covered by light in one second is considered to determine the speed of light. Speed of light is 3*108m/s. The unit of speed of light is meters per second.
How much big is the universe?
It is not currently known how big the Universe is. The observable Universe has a radius of about 47 billion light-years; that is, the most distant objects that can be observed in theory are at that distance. The actual Universe is probably quite a bit bigger.
