As you look deeper into space, you see the universe as it was when it was much younger than it is now. Light from distant galaxies takes time to reach the Earth, so as you look further into the sky, you’re looking at light that has taken longer to reach us and hence started its journey much earlier. Using this fact, it’s possible to probe how the universe used to be billions of years ago, long before humans even existed.
