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.
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.
