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.)

What is the size in square miles of the Universe?
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.

How many kilometers the distance of star in one light year in light years?
The distance of one light year, in light years, is exactly 1.
What is 4085 trillion divided by light years?
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.
How can you measure billions of light years?
Mathematicians do!
How many light years to the Saturn?
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.
How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
what is the distance of equator of our universe?
universe's equator distance is about 150,000,000,000 light years.
The universe is so large that astronomers measure distance between stars instead of kilometers?
light-years, parsecs, and megaparsecs
How long is twenty eight light years?
Twenty eight light years is a unit of distance used to measure vast distances in space. It is equal to the distance that light travels in 28 years, which is approximately 168 trillion miles or 270 trillion kilometers. This distance is used to measure the scale of our universe.
If you are four years away from a place would you be 4 light years away?
No, 'years' is a measure of time and 'light years' is a measure of distance.
What unit of measure is used to measure the distance to the stars?
light years
How many years are in twenty light years?
Zero. Light years are a measure of distance, not time.
What scale is used to measure the universe?
it is either light years or kilometers
What is the relation between light years and people years?
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.
How many years is 587 light years?
587 light years is a unit of distance, not time. It represents the distance that light travels in 587 years.
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.
How many light years are equal to 4.5 billion years?
A light year is a measure of distance, not time. It is the distance light travels in a year.
