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.)
The largest measurement of distance in the universe is the light-year, which is the distance light travels in one year, approximately 5.88 trillion miles (9.46 trillion kilometers). For even larger scales, astronomers use parsecs, where one parsec equals about 3.26 light-years. In cosmology, the observable universe is estimated to be about 93 billion light-years in diameter, representing the largest conceivable distance in terms of our current understanding 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.

The distance of one light year, in light years, is exactly 1.
Well, isn't that a fascinating question! Imagine 28 lightyears as a journey through the vastness of space, where light travels for 28 years to reach its destination. It's like a beautiful painting unfolding in the cosmos, showing us just how immense and wondrous our universe truly is.
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.
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
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.
Light years measure distance in astronomy. It is the distance that light travels in one year, which is about 9.46 trillion kilometers.
No, 'years' is a measure of time and 'light years' is a measure of distance.
Zero. Light years are a measure of distance, not time.
light years
it is either light years or kilometers
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.
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.
