The age of the universe is 13.7 gyrs. The distance to the CMB is 13.7 giga parsecs, maybe I don't understand what a parsec is. Can someone explain?

A parsec is a unit of measurement used in astronomy to describe distances on a galactic scale. It stands for "parallax of one arcsecond" and is approximately 3.26 light years.
A parsec is not directly related to the age of the universe. However, it is often used in astronomical calculations to measure the distance of objects in the universe, which can help determine the age of the universe.
A parsec is significant because it allows us to measure the vast distances of objects in the universe. This is crucial in understanding the size, structure, and age of the universe.
No, a parsec is not used to directly measure the age of the universe. However, it is an important unit of measurement in the calculations and observations that contribute to our understanding of the age of the universe.
A parsec is calculated using trigonometric parallax, which measures the change in an object's apparent position as the Earth orbits the Sun. This measurement, along with other astronomical observations, is used to calculate the distance of an object in parsecs.
