Gravity

We are all familiar with gravity, and it has a constant effect on our lives.  Interestingly, no one knows why gravity works, only how to describe and predict how it affects objects.  How do two sets of molecules exert a force on each other, thousands of miles apart, with nothing actually connecting them?  At its core, gravity is a force that attracts all objects in the universe together.  Each pulling at each other in an infinite web of interactions, all drawing each other closer, even as the universe expands, due to the stronger force of inertia.  The closer two objects get, the stronger the force they exert on each other.

Gravity is powerful enough to hold the largest object firmly on the ground, and to sling objects far into space, if harnessed correctly.  All objects in the universe are constantly in motion, but if any object somehow managed to truly stop, gravity would do two things.  It would force the object into motion again immediately, and cause it to begin to be absorbed by the nearest larger object.

This is similar to how God designed people to interact with one another.  There is some force that ties all people together, even if some times it is too weak to feel or measure.  There are certain patterns in how we affect each other, which can be predicted, even if we don't truly know how they work.  The closer two people are, the stronger the influence they exert on each other.  The connections we have with others can be very powerful.  And if at any point we were to ever totally stop moving or growing, it is the people around us who would get us going again.

God has a tendency to apply good ideas in multiple unrelated ways.  In the same way that solar systems and atoms have the same design to their structure, gravity and relationships have much in common in how they define the effect that we have on others around us, in both the physical and interpersonal realms.
