Isaac Newton, a seventeenth into eighteenth century English scientist and mathematician (among other things), was the first person to propose a mathematical model to describe the gravitational attraction between objects. In spite of the mystery behind the mechanisms of gravity, physicists have been able to describe the behavior of objects under the influence of gravity quite thoroughly. At this point in time, the gravitational force is the troublesome one, the force that resists unification. Physicists today strive toward a "Grand Unified Theory," wherein all four of these forces are united into one physical model that describes the behavior of everything in the universe. Of the four fundamental forces identified by physicists – strong nuclear, electroweak, electrostatic, and gravitational – the gravitational force is the least understood. For all of its influence on our daily lives, for all of its control over the cosmos, and for all of our ability to describe and model its effects, we do not understand the actual mechanisms of gravitational force. What causes objects to fall toward Earth? Why do the planets orbit the sun? What holds galaxies together? If you traveled to another planet, why would your weight change?Īll of these questions relate to one aspect of physics: gravity.
