What does the statement the further away you look in distance the further back you look in time?

The statement "the further away you look in distance, the further back you look in time" refers to the nature of light travel in the universe. When we observe distant celestial objects, such as stars or galaxies, we are seeing them as they were in the past because light takes time to reach us. For example, if a star is 1,000 light-years away, we see it as it was 1,000 years ago. This concept highlights the vastness of space and the relationship between distance and the perception of time in astronomy.
