Why Does Space Feel So Big?

Space is like a giant playground where the swings are miles away and you have to wait forever for the ball to come back. When you look at the stars, you are actually looking into the past because their light takes a long time to travel here. Even our nearest star neighbor, the Sun, takes eight minutes to warm your face. Imagine throwing a ball to the moon; it would take about three days just to get there! The universe is so big that if Earth were a tiny speck of dust, the Milky Way galaxy would be as large as a whole city. We use units like light years to measure these huge gaps because counting miles gets too confusing with all those zeros. This vastness makes every trip between stars feel like an epic adventure.
