13.2 billion light-years.
since you measure space in light years, not very acurate. Distances in space are as accurate as the tools by which they are measured.
They use scientific notation because of the vast distances in space.
Who performed the longest space journey in the year 2007?
Space key
Russia holds the record for the longest continuous time spent in space by a country. The cosmonaut Valeri Polyakov set the record by spending 437 days aboard the Mir space station in the 1990s.
Gravity is the universal force that is most effective over the longest distances. It acts between all objects with mass and decreases with distance according to the inverse square law, but it has an infinite range.
Distances in space are measured using a variety of methods, such as parallax for nearby stars, radar for planets in our solar system, and redshift for galaxies and other objects in the universe. These measurements help astronomers understand the scale of the universe and the vast distances between objects in space.
We can measure distances in space in light years...1 light year is equal to the distance light travels in 1 year.They are very accurate...............
Shannon Lucid set the U.S. record for longest stay in space in 1996
Distances in space are measured using light years, which represent the distance light travels in one year. This unit is used because space is vast and traditional units like kilometers or miles are too small to accurately measure these distances.

The longest wavelengths on the electromagnetic spectrum are called radio waves. They have the lowest frequencies and carry information through long distances.
