One of the fun things to do with astronomy (and science in general) is to imagine what it would be like if things were different. For example, right now the Moon orbits the Earth at an average distance of about 384,000 kilometers (238,000 miles). Even though that makes it the nearest astronomical object in the Universe, that’s still pretty far — a four-day ride in a space capsule, for example.
But what if it were closer? “Smart is the new sexy” wants to know the consequences, and what about you? If you do, make yourself comfortable and watch. You will be amazed. Let’s go.
