It's the fastest speed anyone can prove exists. Any speeds in excess of light speed are still just theory. Some scientists believe it is the fastest speed that will ever be achievable.( a cosmic speed limit.)
First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known. The observable Universe has a radius of about 46 billion light-years. Convert that to kilometers or miles if you like. One light-year is about 10 million million kilometers. But the entire Universe is probably much, much bigger.First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known.

The distance of one light year, in light years, is exactly 1.
4085 is a pure number. A light year is a measure of distance whose numeric value depends on the units used. There is, therefore, no sensible answer to the question.
Mathematicians do!
The distance from the Earth to Saturn varies - depending on whether both planets are on the same or opposite sides of the sun. At their nearest the distance is approx 0.000127 light years.
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
universe's equator distance is about 150,000,000,000 light years.
light-years, parsecs, and megaparsecs
it is either light years or kilometers
No, 'years' is a measure of time and 'light years' is a measure of distance.
light years
Zero. Light years are a measure of distance, not time.
Light-year is a physical measurement related to Universe Issues, and it comprises huge distances across the Universe. People's years is a measurement related to the lifespan, not only for humans but also for all living creatures. The difference is that People years is a measure only related to life, while light-years is not. The point is that a light year is a measure of distance NOT time. It does get people confused sometimes. It's how far light goes in a year.
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.
Light years is a measure for distance, the distance light travels in one year. For the light to travel 587 light years, it takes 587 years.
A light year is a measure of distance, not time. It is the distance light travels in a year.
None. A light year is a measure of distance, not of time.
