How Small Are You? From Your Bed to the Observable Universe | Fall Asleep To

How small are you compared with the universe? Drift off with a gentle tour of cosmic scale, from your room to the Moon, the Sun, nearby stars, the Milky Way and the observable universe, before returning to the atoms inside you. The observable universe is the region whose light can reach us, not a physical wall or the known boundary of all existence. Sizes and distances are rounded to help you picture the journey.
