Exploring the mysteries of the cosmos has always fascinated human minds. Among the various means to achieve it, observing distant galaxies is one of the most intriguing methods. But, how does looking at distant galaxies allow us to look back in time? The answer lies in the massive distances that light travels from faraway galaxies to reach us. Since light has a finite speed, it takes time to travel from one point to another. As a result, the light that we observe from these galaxies is actually old light that was emitted hundreds or thousands of years ago. Therefore, when we gaze at a distant galaxy, we are essentially seeing its past.
