The **gravitational constant**, or **G**, is the universal constant of gravity, first discovered on Earth by the Human scientist Sir Isaac Newton. It played a large role in his theory of universal gravitation, in the following formula:

where F_{g} is the gravitational force between two bodies, m_{1} is the mass of one body, m_{2} the mass of the other body and r the distance between the centers of the two bodies.

In 2366, when Q temporarily became Human and hoped to join the crew of the USS *Enterprise*-D, Geordi La Forge and Data asked him to assist in preventing the moon of Bre'el IV from crashing into the planet. Q suggested changing the gravitational constant of the universe. Although this was beyond the capabilities of the *Enterprise* crew, it did lead to one possible solution: extending the ship's warp field around the moon, thus reducing the *moon's* gravitational constant.
